Crestasee, also called Lake Cresta, is a clear mountain lake on the eastern side of Flims near Trin in Graubünden. Surrounded by dense forest, it is a protected natural landmark of regional importance and a popular place for swimming, hiking, paddling, and quiet time outdoors. Unlike many roadside lakes, Crestasee is accessible only on foot, so every visit includes at least a short walk through the forest.
Quick Answer
Crestasee is a small, clear mountain lake between Flims and Trin in Graubünden. You reach it only on foot, usually after a 15–20 minute walk from the nearest bus stop or parking area. In summer, you can swim, rent a rowing boat, SUP, or tandem kayak, eat on-site, and hike nearby forest trails.
Key Takeaways

- Summer activities include swimming, hiking, rowing-boat rental, stand-up paddleboarding, and rented two-person kayaks.

- Check current fire, weather, bathing, and operating conditions shortly before your visit because restrictions can change.
How to Get to Crestasee
Crestasee does not have road access directly to the shoreline. The official Flims Laax visitor information describes the lake as accessible only on foot, so plan for a short forest walk regardless of whether you arrive by car or public transport. You can check current destination access information on the official Flims Laax Crestasee page.
Getting to Crestasee by Public Transport
If you are arriving by rail from another part of Switzerland, travel to Chur first rather than looking for a train to Flims or Laax. From Chur, continue by PostBus toward the Crestasee area.
The official Crestasee access information directs passengers traveling from Chur toward Flims to the Felsbach Crestasee stop. When approaching from the Ilanz/Flims side toward Chur, the listed stop is Trin Mulin, Crestasee. The final approach is on foot. Check the current timetable before leaving because bus schedules can change by season.
Pro Tip: Search your complete journey to the relevant Crestasee-area stop before departure rather than assuming Flims or Laax has a railway station. This gives you the current train-to-Chur and PostBus connection in one itinerary.
Getting to Crestasee by Car
Drivers approach through Trin Mulin and follow signs toward Crestasee. The official natural-bath site lists parking areas 1 through 5, with parking area 5 closest to the lake. From the large forest parking area, allow about 15 minutes for the walk to Crestasee. Vehicle traffic toward the lake is prohibited beyond parking area 5.
Coming from an Airport
Flims Laax lists Zurich, Basel-Mulhouse, and Milan Malpensa among the closest international airports. Zurich is a practical gateway for many visitors because you can continue by Swiss rail to Chur and then by PostBus toward Crestasee. Check the official Flims Laax arrival guide when planning the longer journey.
Activities to Enjoy at Crestasee
Crestasee works well as both a relaxing swimming destination and a stop on a longer day outdoors. The lake’s clear water, wooded shoreline, and network of surrounding trails make it especially appealing in summer, but walking routes in the wider area can also be enjoyed outside the bathing season when conditions are suitable.
Swimming and Sunbathing
Swimming is one of Crestasee’s main summer activities. During the staffed bathing season, visitors pay admission to use the natural-bath area. The official Crestasee site currently lists standard day admission at CHF 7 for adults, CHF 5 for students and apprentices, and CHF 3 for children ages 6–16, with additional reduced categories available.
The kiosk and staffed bathing operation run seasonally and are weather-dependent. The published July and August schedule is approximately 09:00 to 17:30. Crestasee remains accessible outside the staffed hours, but the official site states that there is then no bathing supervision and no kiosk service. Always check Crestasee Naturbad for current opening information before traveling.
Warning: Swimming outside staffed bathing hours is not supervised. Mountain weather and water conditions can also change quickly, so assess conditions carefully and supervise children closely around the water.
Boat, SUP, and Kayak Rentals
You do not need to bring your own watercraft. The official rental service offers rowing boats, stand-up paddleboards, and two-person kayaks. Current published rates are CHF 12 for 30 minutes or CHF 20 for one hour for each of these rental types.
There is an important distinction between the rental equipment and privately brought craft. Crestasee’s published rules ask visitors not to launch their own canoes, kayaks, or pumpfoil boards. Boats and SUPs should also stay out of the sensitive reed areas.
Hiking Around Crestasee
The surrounding Flims forest offers routes ranging from short access walks to longer circuits. Graubünden Tourism lists a simple 4.6 km Crestasee circular hike from Trin Mulin that takes about 1 hour 15 minutes and follows a broad, stroller-friendly route through forest and meadows. Longer hikes can link Crestasee with Caumasee, Conn, or viewpoints toward the Rhine Gorge.
Bring shoes suitable for forest paths even if you are visiting mainly to swim. After rain, shaded sections can stay damp, and conditions outside summer may require warmer or more protective footwear.
Where to Stay at Crestasee
| Accommodation Option | Location | Best For | What to Know |
|---|---|---|---|
| Gasthaus Crestasee | At Crestasee | Staying as close to the lake as possible | The property lists seven double rooms with shared bathrooms and an on-site restaurant. |
| Flims hotels and apartments | Flims Dorf / Flims Waldhaus | Easy access to regional buses, restaurants, hiking, and other Flims sights | Compare current availability through the official Flims Laax accommodation directory. |
| Laax hotels and holiday apartments | Laax | Combining Crestasee with a wider Flims Laax holiday | Use regional bus connections or drive toward Trin Mulin for the lake approach. |
| Trin-area lodging | Trin / Trin Mulin | A quieter base near the eastern approach to Crestasee | Useful for travelers who want walking and PostBus access without staying in the larger resort areas. |
If being beside the lake matters most, Gasthaus Crestasee is the most directly relevant option to check. For a larger selection of hotels and holiday apartments, Flims and Laax provide many more choices. Because accommodation prices and ratings change by date and booking channel, compare current rates rather than relying on fixed generic price estimates.
Best Places to Eat at Crestasee
You can eat directly at Crestasee instead of returning to Flims for every meal. The two most useful options are the seasonal natural-bath kiosk and Gasthaus Crestasee.
Gasthaus Crestasee
Gasthaus Crestasee operates a restaurant beside the lake and describes its cooking as a mix of traditional and creative dishes. Its current site highlights house-made food, including pizokels and desserts. Opening hours, kitchen hours, special closure dates, and reservation information can change, so check the Gasthaus Crestasee website before planning a meal around your visit.
Crestasee Kiosk
The seasonal kiosk provides an easier option for swimmers and hikers who want a casual meal or snack. Its published summer selection includes warm food, snacks, ice cream, coffee, and drinks, with some offerings changing during the season. Kiosk operation is weather-dependent and follows the staffed bathing season.
Note: Do not assume the kiosk and restaurant follow the same schedule. They are separate operations, so check each one’s current hours if food is an important part of your visit.
Tips for Visiting Crestasee
Summer is the easiest season for combining swimming, sunbathing, boat rental, and hiking. July and August are part of the main bathing period, so they also bring the greatest demand for lake facilities. Arriving earlier in the day can give you more time before the staffed bathing operation closes.
Autumn is attractive for forest walks and photography as the colors change, although swimming conditions and kiosk service become less dependable as temperatures fall. Crestasee is also part of winter walking routes, but snow, ice, and cold conditions require appropriate footwear and clothing.
What to Bring
- Comfortable walking or hiking shoes for the final forest approach.
- Swimwear and a towel during warm weather.
- Layers and rain protection because mountain weather can change.
- Drinking water, although drinking water is also available from a tap near the bathing facilities.
- Sun protection for time on the lawn, pier, or water.
- A camera or phone for lake, forest, and mountain photography.
Facilities near the kiosk include toilets, changing rooms, lockers, a shower, a drinking-water tap, a children’s bathing area, and a raft in the lake. These make Crestasee more practical for a longer summer visit than its remote forest setting may initially suggest.
Local Etiquette and Nature Protection at Crestasee
Crestasee is a protected natural area, so local rules are more useful to visitors than generic descriptions of regional customs. Respecting them helps protect the shoreline and keeps the bathing area comfortable for other guests.
- Dogs: Keep dogs on a leash within the site and respect the dog-free children’s bathing area and pier. Dogs may enter the water in permitted areas around the lake.
- Drones: The Crestasee rules ask visitors not to fly drones anywhere on the site and refer to the municipality’s drone restriction.
- Camping: Wild camping is prohibited in the municipalities of Flims and Trin.
- Fishing and diving: These are prohibited at Crestasee without permission.
- Reeds: Do not take boats or SUPs into the sensitive reed areas.
- Private watercraft: Do not launch personal canoes, kayaks, or pumpfoil boards.
- Music: Avoid loud music that disturbs other visitors.
Warning: As of August 17, 2026, the official Crestasee site reports that the public grill area is closed because of dryness and a government-ordered fire ban. Fire restrictions can change quickly, so check the current Crestasee rules immediately before your visit.
Must-See Attractions Near Crestasee
Felsbach Gorge
Felsbach Gorge is one of the easiest natural sights to combine with Crestasee. The Flem river has cut a narrow gorge through the forest between the Flims and Trin area, and hiking routes link it with the lake. It is especially refreshing to walk near the gorge on a warm day.
Rhine Gorge and Il Spir
The Rhine Gorge, often promoted locally as the “Swiss Grand Canyon,” is one of the major natural sights in the region. The Il Spir viewing platform near Conn gives a wide view into the gorge and can be reached from the Flims Waldhaus area by hiking trail. Visit the official Rhine Gorge guide for current route information.
Caumasee
Caumasee is another well-known forest lake near Flims. Longer walking and cycling routes can connect Caumasee, Conn, and Crestasee, making the two lakes a natural combination for visitors who want a fuller day outdoors.
Lake Laax
Lake Laax is a separate bathing lake in Laax with a summer beach area. It is useful for travelers staying in Laax or exploring the destination’s three main swimming lakes: Lake Cresta, Lake Cauma, and Lake Laax. Winter skiing takes place in the wider LAAX mountain resort rather than on the lake itself.
Crestasee combines clear water, forest scenery, swimming, easy walking, and access to several of the Flims-Trin area’s best-known natural sights. The most important part of planning is understanding that the shoreline is reached on foot and that bathing services, rentals, food, fire restrictions, and supervision can change with the season and weather. With those details checked in advance, the lake works equally well for a short swim stop or a longer day of hiking and exploring.
Before traveling, check the official Lake Cresta visitor page and Crestasee Naturbad for current access, admission, weather-dependent operations, and visitor rules.
