Wild camping at the Fil de Cassons

Flims bans camping on the whole commune, and the people voted for it

Start with the norm that actually reaches this crest, because it is not the one in the request. The Gastwirtschaftsgesetz der Gemeinde Flims, in the version the commune publishes today under "Stand 2000", devotes one short article to camping. Art. 17, headed "Camping", is two sentences long, and here it is in full: "Das Campieren ausserhalb von bewilligten Campingplätzen ist verboten. Über Ausnahmen kann der Gemeinderat befinden." Camping outside authorised campsites is prohibited. The communal council may decide on exceptions.²

Nothing in that article is limited to the village, the lakes or the valley floor. It is a commune-wide rule, and the commune says so itself in its own FAQ: "Ausser auf dem dafür vorgesehenen Campingplatz in Flims Waldhaus ist das Campieren auf dem ganzen Gemeindegebiet verboten." Except on the campsite provided for it in Flims Waldhaus, camping is prohibited on the entire communal territory. The same page adds a detail that is worth knowing before you argue with anyone about it: "Der Flimser Souverän hat diesem Verbot anlässlich einer Urnenabstimmung mit grossem Mehr zugestimmt." The Flims electorate approved this ban in a ballot, by a large majority.⁴

The canton confirms that a commune may do this. Graubünden's Amt für Raumentwicklung sets out the frame in its guidance note "Camping und Raumplanung": "«Wildes Zelten»: Darunter versteht man einen kurzzeitigen Aufenthalt im freien Gelände ... Die Gemeinde ist befugt, dies zu verbieten oder mit einer entsprechenden Bewilligung zu erlauben." Wild tenting means a short stay in open terrain, and the commune is entitled to prohibit it or to allow it with a corresponding permit. That is the cantonal mirror of Flims art. 17: a ban in the first sentence, a permit route in the second.⁶

The fine is communal, and it is worth stating precisely rather than dramatically. Art. 18 of the Flims act sends offences onward: violations "werden im Rahmen des kant. Gastwirtschaftsgesetzes vom Gemeinderat geahndet". The cantonal act is the Gastwirtschaftsgesetz für den Kanton Graubünden, BR 945.100, adopted by popular vote on 7 June 1998, and its art. 11b para. 1 reads: "Übertretungen der Vorschriften der kantonalen oder kommunalen Gastwirtschaftsgesetzgebung werden von der Gemeinde mit Busse bis 10 000 Franken geahndet, soweit nicht Strafbestimmungen des Bundesrechts Anwendung finden." Up to ten thousand francs, imposed by the commune.³

Read that as what it is: a ceiling for a whole category of offences under hospitality law, most of which concern licensed businesses, and it is deliberately high at the top end because art. 11b para. 2 lifts the cap entirely where there is profit-seeking. It is not a fixed-penalty ticket, and there is no tariff line anywhere that puts a number on one quiet night on a ridge. What it does tell you is which authority acts: the commune, not the canton and not the federal government. And it is emphatically not the CHF 150 that hikers know from federal game reserves. That tariff lives only inside a Jagdbanngebiet, and the nearest one, Graue Hörner, starts 6.3 km from this crest.¹

The one exception in the destination, and the two words that carry it

Here is the sentence that makes this article "it depends" instead of "no". Flims Laax, the destination organisation for Flims, Laax and Falera, publishes its position on wild camping on its own camping page, and it singles out one commune out of three: "In der Destination Flims Laax ist das Wildcampen verboten. Lediglich auf dem Gemeindegebiet Flims darfst du im Rahmen einer Mehrtages-Hochtour biwakieren. Strikte Sperrzonen sind dabei Naturschutzgebiete, Naturpärke, Jagdbanngebiete, Wildruhezonen sowie Auen- und Moorlandschaften." Wild camping is prohibited in the destination. Only on the communal territory of Flims may you bivouac within a multi-day high tour. Strictly closed zones are nature reserves, nature parks, federal game reserves, wildlife rest zones and floodplain or moor landscapes.⁵

Look at the verbs, because they are doing the work. The banned activity is "Wildcampen". The permitted activity is "biwakieren", to bivouac, and it is permitted only "im Rahmen einer Mehrtages-Hochtour". Art. 17 of the communal act bans "Campieren". A Swiss camping ban that is written against camping does not automatically swallow a single night in a bivvy bag on a high ridge, and here the commune's own destination draws that line explicitly rather than leaving it to be argued. That is unusually clear for a Graubünden commune, and it is why this spot has an answer at all.

Now the honest part, and it is the reason this is not graded "legal". That sentence is published by the destination organisation, not printed in the statute. The statute's own hook for it is the second sentence of art. 17, "Über Ausnahmen kann der Gemeinderat befinden", which reserves exceptions to the communal council and makes them a matter of discretion rather than of right. So the sensible way to read the destination's wording is as the commune's published practice: reliable enough to plan around, not a licence you can wave. If your trip does not plainly answer to "Mehrtages-Hochtour", the clean move is to ask the council, and the address is at the end of this article.²⁵

And note what the same sentence closes. The list of strict no-go areas names Wildruhezonen, wildlife rest zones, with no season attached to it. That is the hinge of the whole question, and it is where the request's instinct turns out to be right after all.

And there is a second page you have to read next to the first one. The same destination runs a page for the Flimserstein and Cassons itself, and on it the tone changes. It asks visitors to leash the dog during the dotterel protection period from 18 August to 10 September, and then: "Verzichte zudem auf Drohnen sowie auf das Campieren und Biwakieren." Refrain from drones and from camping and bivouacking. Note that this names both verbs, where the camping page permitted one of them.¹⁰

Read the two registers carefully, because the page itself separates them. For the winter zone it writes "rechtsverbindlich" and "Zutrittsverbot", legally binding and a no-entry rule. For summer camping it writes "verzichte", please refrain. So this is a request, not a prohibition, and it does not change what the law says. It does change what a decent visitor does. The dotterel is a Red List species that crosses thousands of kilometres and rests on exactly these bare ridges to rebuild reserves, and the crest of the Fil de Cassons is the ground it rests on. If you go, go outside 18 August to 10 September, and if you want the certainty, take the Gemeinderat route in the last section instead.¹⁰

Crap da Flem closes in winter, and still decides your pitch in summer

The crest pin is inside a wildlife rest zone. Federal geodata queried at LV95 2'739'323 / 1'193'628, WGS84 46.87917 / 9.26652, terrain height 2'651.9 m, returns exactly one protected-area hit: Wildruhezone Crap da Flem, no. 275.0. Its record is unusually informative, so here are the fields that matter. Protection status: "rechtsverbindlich", legally binding, not merely recommended. Legal basis: "Gemeindebeschluss", a communal decision. Year of decision: 2025. Provision code R20, described as "Zutrittsverbot (zu Fuss und Wintersportarten)", a no-entry rule for travel on foot and for winter sports. And the protection period, the field that changes everything here: "20.12. - 30.04."⁷

That distinction matters, because "recommended" and "binding" are not the same thing in this dataset and people routinely read one as the other. This one is binding. It is also, for eight months of the year, simply not running. From 1 May to 19 December the zone's own entry rule does not apply, and walking the crest in August breaks nothing.

So why does the zone still decide where you sleep? Because the exception you need is not the zone's rule, it is the destination's bivouac tolerance, and that tolerance excludes wildlife rest zones flatly, with no dates attached. Inside the zone you therefore fall back on art. 17 with no exception to stand on, in any month. Outside it, in summer, you have both: no zone rule in force and the published bivouac route open. Two instruments, two logics, and the answer only comes out clean when you keep them apart.⁵⁷

Where the zone gets its force, and what it costs. Art. 27 para. 2 of the Graubünden hunting act lets communes restrict the right of access to wildlife areas in place and time when disturbance exceeds the locally usual level. That is why this zone is filed as a "Gemeindebeschluss": Flims made it, on cantonal authority. The sanction is Art. 47 para. 1 of the same act, a fine of up to CHF 20'000 for intentional or negligent breaches, and Art. 47a adds a fixed-penalty route for simple, clearly defined cases, capped at CHF 500. That second number is the one a walker would realistically meet, and it applies in winter, not to a summer night outside the zone.⁷

For completeness, the neighbours. The next wildlife rest zones are Bargis, no. 176.0, 2.0 km away, and Preuls, no. 130.0, 2.7 km away, both legally binding and both carrying the identical 20.12. to 30.04. period, which is the standard Graubünden winter window. Nothing else federal is close: the BLN landscape Ruinaulta begins 6.2 km off, the federal game reserve Graue Hörner 6.3 km, the lowland mire Plaun Segnas Sut 2.3 km and its moor landscape 1.9 km, and there is no park of national importance and no forest reserve within 8 km.¹

Where outside actually is: 190 to 270 m west-north-west

First, the terrain question, because a ridge called "Fil", a thread, invites the wrong picture. This is not a knife edge. A 21 by 21 grid on the 25 m terrain model, 500 m square and centred on the pin, spans 2'448 to 2'674 m with a median slope of 25.5 degrees, and 62 of its 361 interior points come in under 10 degrees. The pin itself measures 2.2 degrees. There is genuinely flat ground up here, a long way above the treeline, and the flattest of it runs west-north-west along the crest.¹

Second, which of it is outside the zone. Each flat bench was tested against the mapped zone boundary itself, not against an eyeballed line on a map. Four of them sit outside, and all four are on Flims territory:

• 46.88034 / 9.26360, LV95 2'739'098 / 1'193'753, 2'663 m, slope 1.7 degrees, 145 m clear of the zone boundary, 258 m west-north-west of the pin. This is the one to aim for.
• 46.88057 / 9.26361, LV95 2'739'098 / 1'193'778, 2'664 m, 2.2 degrees, 147 m clear, 271 m west-north-west.
• 46.87988 / 9.26424, LV95 2'739'148 / 1'193'703, 2'660 m, 1.4 degrees, 92 m clear, 191 m west-north-west.
• 46.88010 / 9.26458, LV95 2'739'173 / 1'193'728, 2'662 m, 0.4 degrees, 69 m clear, 181 m west-north-west. The flattest patch measured anywhere in the box, but also the closest to the line.

Third, what is on that ground. Nothing. All four were queried against ten federal layers, wildlife rest zones, federal game reserves, BLN, floodplains, lowland and raised mires, moor landscapes, Emerald sites, forest reserves and parks of national importance, and every single one comes back empty, while the pin 200 m away correctly returns its wildlife rest zone. A deliberately invalid layer id surfaced as HTTP 400 in the same runs and a known-positive control inside the Kiental game reserve hit as it should, so those zeros are real zeros and not a silent query failure.¹

And the honest caveat. A zone boundary is a line in a database, not a fence on a hillside; there is nothing on the ground to tell you which side you are on. That is why the margin matters more than the exact metre, and why the recommended bench is the one with 145 m of clearance rather than the flattest one with 69 m. Take a GPS, take the margin, and if in doubt walk further west.

Being inside the exception, and who to ask if you are not

The condition to take seriously is "Mehrtages", multi-day. And there is a piece of local history that makes this crest fit the wording far better than it would have ten years ago. A cable car used to run to exactly here. The Swiss cable car inventory lists it as no. 71.022, "Naraus - Fil da Cassons", a Pendelbahn built by Von Roll in 1956 and rebuilt in 1974 and 1986, valley station at 1'846 m, mountain station at 2'644 m, which converts to LV95 2'739'262 / 1'193'514, roughly 130 m from the pin in this article. The last line of its record reads "Anlage abgebrochen 2016": the installation was demolished in 2016.⁸

That is only half the story, and the other half arrived recently. Flims Laax states that from winter 2025/26 the FlemX reaches Cassons, so the crest has a lift again after nine years without one. In summer, what remains is the chairlift chain from Flims up to Naraus at about 1'846 m, and from there roughly 810 m of ascent on foot, or the whole climb from Flims at around 1'100 m. The Segneshütte at 2'104 m, 2.4 km away, is the natural anchor for a genuine tour over the Flimserstein toward the Segnesboden.⁸

Which lets you answer the "Mehrtages-Hochtour" question yourself, honestly. A multi-day crossing of the Flimserstein that happens to bivouac on this crest is squarely what the destination's sentence describes. Driving to Flims, riding to Naraus and walking up for a sunset is not a multi-day tour, whatever else it is, and no amount of goodwill turns it into one. That is the difference between standing on the published exception and standing on nothing, and it is the part a general "wild camping is banned in Switzerland" article will never tell you.

If your trip does not clearly qualify, there is a named route. Art. 17 sentence two puts exceptions in the hands of the Gemeinderat, so ask them. Gemeindeverwaltung Flims, Via dil Casti 2, 7017 Flims Dorf, telephone +41 81 928 29 29, with a contact form on the commune's site; the phone is staffed Monday to Thursday 08.00 to 11.30 and 13.30 to 16.30, Friday to 16.00. No fee for such a permission is published, and no informal rate for it surfaced anywhere in the research for this article, so do not budget for one and do not offer one.²⁴

Fire, separately, is a firm no. The commune answers the fire question directly: outside the official fire places, lighting a fire on public ground is prohibited, and that extends to disposable barbecues. When the FAQ was read for this article it additionally carried an absolute fire ban outside the settlement area. Drought bans come and go, so check the current status before you travel, but on this crest the answer is a stove or nothing in any case.⁴

The rest is the usual, and up here it is what keeps the exception alive. Arrive late, leave at first light, one small tent or a bag, everything carried out including the paper, no trace on the grass, and give the marked routes and any grazing stock a wide berth. The tolerance you are relying on is a published courtesy resting on a discretionary power, and courtesies are withdrawn when they are abused.⁹

General rules for wild camping

The list below is not the law. It is what keeps the answer at 'it depends' rather than at a flat no, and every item on it is something you can check yourself before you go.

• No fire. An open fire has no place in the mountains. A gas stove is enough.
• Pitch late, strike early. Set up towards evening, gone again early. A bivouac is one night, not a base camp.
• Leave no rubbish. Everything you carry up you carry down, organic scraps and toilet paper included.
• At least 50 metres from any water for the big business, so you do not foul what people and livestock drink.
• Stay small and quiet. A small group, no speaker, no drone, dogs on the lead, and the alp staff's word goes.

Disclaimer

This article reflects my research and assessment to the best of my knowledge, as of September 2026. It is based on the publicly accessible and official sources linked below. It does not replace legal advice and is not a binding statement of the current legal situation.

The verdict covers the crest named in the article and a single night. It rests on a communal camping ban that is real and voted in, on a published exception of the destination organisation whose statutory hook is a discretionary power of the communal council, and on measured geodata for the wildlife rest zone boundary. A published practice can change and a discretionary permission can be refused. The wildlife rest zone is legally binding, and its boundary is not marked on the ground. Before every tour, check the current sources yourself and follow instructions on site. A genuine emergency bivouac in distress is a separate question from a planned camp. Anyone who spends the night outside bears responsibility for their own conduct and any consequences themselves. Hikebeast, Leon Helg and Saftladen GmbH accept no liability for decisions made on the basis of this text, and call on no one to break applicable law.
