Obersee by Season: Activities and Events Throughout the Year

Obersee: A Complete Travel Guide to Switzerland’s Hidden LakeObersee — often translated as “Upper Lake” — refers to several lakes in German-speaking regions, but in Switzerland it commonly evokes the serene, crystalline waters tucked away in alpine valleys. This guide focuses on the Swiss Obersee near Glarus/Filzbach and the nearby smaller Obersee in the canton of Schwyz (both popular among visitors), concentrating on practical travel information, top activities, access, accommodation, photography tips, and local culture to help you plan an unforgettable trip.

Quick facts

• Location: Multiple lakes named Obersee in Switzerland; the best-known are near Glarus/Filzbach (Glarus canton) and near Einsiedeln/Altendorf (Schwyz canton).
• Best time to visit: Late spring through early autumn (May–October) for hiking and boating; winter for snow-covered scenery but limited access.
• Nearest major cities: Zurich (1–1.5 hours by car/train) and Lucerne (about 1–1.5 hours depending on which Obersee).
• Language: German (Swiss German dialects); locals in tourist areas usually speak good English.
• Currency: Swiss franc (CHF).

Which Obersee should you visit?

There are several Swiss lakes named Obersee. Two accessible and picturesque ones are:

• Obersee (Glarus/Filzbach) — an alpine lake framed by steep limestone cliffs and forests; excellent for hiking and quiet nature trips.
• Obersee (near Einsiedeln/Altendorf in Schwyz) — smaller, often visited together with nearby villages and cultural sites.

Choose based on whether you want more rugged alpine scenery (Glarus) or a gentler landscape with easier access and nearby cultural attractions (Schwyz).

Getting there

• By car: Switzerland’s roads are excellent. From Zurich, expect roughly 1–1.5 hours depending on which Obersee; conditions vary in winter. Use local parking at trailheads; some parking is limited in high season.
• By public transport: Swiss trains and buses connect major cities to nearby towns (Filzbach, Glarus, Einsiedeln, Altendorf). From those towns, local bus routes or short taxi rides reach trailheads and lakes. Check SBB.ch for schedules and connections.
• On foot/bike: Many visitors arrive as part of multi-day hikes or cycling routes. Trails are well-marked.

Top activities

• Hiking: Well-marked trails range from easy lakeside walks to challenging alpine routes. Popular hikes include loop trails around the lake and connections to ridge trails with panoramic views. Bring sturdy footwear and a map or offline GPS.
• Swimming & paddling: In summer, the clear water invites swims; temperatures can be cool. Non-motorized boats or stand-up paddleboards are ideal—check local rental availability.
• Picnicking & wildlife watching: Forested shores provide peaceful picnic spots; birdlife and small alpine mammals are common.
• Photography: Sunrise and sunset light on cliffs and reflections make for dramatic photos. Long exposures and polarizing filters help with glare and color saturation.
• Winter scenery: If accessible, frozen or snowy lakesides offer striking, minimalist landscapes—exercise caution on ice; local authorities post safety information.

Where to stay

• Nearby towns: Glarus, Filzbach, Einsiedeln, Altendorf offer hotels, guesthouses, and B&Bs. Book early in summer.
• Mountain huts: For multi-day hikes, consider Swiss Alpine Club huts or private mountain lodges. Reservations required in peak season.
• Camping: Wild camping rules in Switzerland are strict—use official campgrounds.

Food & local culture

• Cuisine: Swiss-German influences—cheese, rösti, sausages, lake fish where available. Mountain inns (alpstübli) serve hearty local dishes.
• Festivals: Small-town festivals occur in summer—check local tourism websites for dates. Respect local customs, especially quiet hours (often observed in villages).

Practical tips

• Weather: Alpine weather changes fast—layer clothing, pack rain protection, sunscreen, and hat.
• Safety: Trails can be steep and rocky—carry water, basic first-aid, and inform someone of longer routes. Mountain rescue numbers are posted locally.
• Cash & cards: Cards widely accepted; carry some CHF for small vendors.
• Waste: Switzerland is strict about littering—carry out what you bring and use recycling bins.
• Permits & rules: Check for any boating, fishing, or drone-use restrictions before planning activities.

Photography checklist

• Camera or good smartphone, spare batteries, extra memory card.
• Wide-angle lens for landscapes, telephoto for distant peaks or wildlife.
• Polarizing filter and ND filter for reflections and long exposures.
• Lightweight tripod for low-light shots and long-exposure water smoothing.
• Protective dry bag for sudden rain.
