The Overview
Michael Fulton
Melbourne-based skier and snowboarder with 50+ resorts across 5 continents. Specialises in Australian resorts and international resort comparisons.
Chäserrugg – Unterwasser operates between 900 and 2262 metres across 1362 vertical metres in eastern Switzerland's Toggenburg region. The resort distributes 50 kilometres of piste across 23 marked runs serving the linked villages of Unterwasser, Alt St Johann and Wildhaus. Terrain breaks down as 16 per cent beginner, 80 per cent intermediate and 4 per cent advanced, with 2 kilometres of additional ski routes for freeriders. Annual snowfall averages 4.3 metres, supplemented by snowmaking coverage across key sectors.
Intermediate skiers dominate the clientele, drawn to the area's cruising terrain spread beneath the seven-peaked Churfirsten massif. The Chäserrugg East Run descends 5 kilometres through largely untouched terrain from the 2262-metre summit to Espel pavilion. Valley runs to both Unterwasser and Alt St Johann provide genuine top-to-bottom skiing across the full vertical. A funpark operates for freestylers below the Chäserrugg summit, whilst practice slopes at Iltios and Alt St Johann cater to families.
The resort distinguishes itself through architecture rather than extreme terrain, with six Herzog & de Meuron structures integrated since 2015. The award-winning timber summit building at 2262 metres exemplifies the collaboration between Swiss design and mountain infrastructure. Toggenburg received Landscape of the Year 2021 recognition for infrastructure renewal that emphasises landscape preservation over commercial visual pollution. The area maintains agricultural traditions alongside tourism, creating an atmosphere closer to working mountain communities than purpose-built resorts.
Chäserrugg operates independently without major pass affiliations, though the Chäserrugg Pass covers summer and winter access across the network. The 2025-26 season runs 30 November to 6 April with typical mid-November to mid-April operations. Night skiing operates Fridays 18:30 to 21:30 from late December through February at Alt St Johann-Sellamatt. The resort suits intermediate skiers seeking uncrowded terrain, families prioritising manageable scale, and visitors valuing architectural merit alongside skiing.

When to visit Chäserrugg - Unterwasser (Toggenburg)
The 2025-26 season operates 30 November 2025 to 6 April 2026, closing 12 April for an 18-day maintenance period before summer operations commence 1 May. Typical season length extends late November through mid-April, delivering approximately four and a half months of skiing. Lift operations run 08:30 to 16:30 daily, with earlier 08:15 starts during weekends and holiday periods. The resort benefits from north-facing valley orientation despite its position as Switzerland's most northerly major ski area.
Annual snowfall averages 4.3 metres, with eastern Switzerland's snow belt delivering reliable winter storms throughout the season. Elevation advantage between 900 and 2262 metres ensures snowpack longevity even during marginal periods at lower altitudes. Snowmaking covers 10 kilometres of piste with 24 cannons, concentrating on key runs and valley approaches. Current season data shows 190-centimetre base depth with 185 centimetres accumulated season total, reflecting above-average early-season conditions for the 2025-26 winter.
January through March delivers most consistent powder conditions, whilst spring skiing extends into April with reliable coverage on higher aspects. December and early January suit visitors avoiding peak crowds, though snowpack depth may vary year to year. North-facing slopes preserve powder longer than southern exposures, allowing strategic terrain selection throughout the day. The Chäserrugg massif's varied aspects create microclimates where skiers can follow optimal conditions between sun-warmed southern runs and powder-preserving northern bowls.
Friday night skiing operates 18:30 to 21:30 from late December through February end on the 3-kilometre floodlit Alt St Johann-Sellamatt run. March events include NostalSki vintage equipment races and live music at Espel Pavilion on Saturday afternoons. August brings Federal Day sunrise celebrations with 05:00 first lifts and 23:30 final descents. The traditional Stöfeli alpine service in August features yodelling and alphorn performances at 1662 metres, accessible via special gondola operations.

Getting there
Getting to Chäserrugg - Unterwasser (Toggenburg), and where to stay
Chäserrugg – Unterwasser occupies the upper Toggenburg valley in canton St Gallen, eastern Switzerland, between the Säntis massif and the seven-peaked Churfirsten range. Base villages sit at 900 to 911 metres elevation, with Unterwasser and Alt St Johann separated by approximately 300 metres and Wildhaus positioned 1.2 kilometres west. The Thur river drains the valley, which forms part of the broader Obertoggenburg region characterised by working farms and traditional wooden architecture. The easternmost Churfirsten peak, Chäserrugg itself, rises to 2262 metres with dramatic southern cliffs plunging toward Walensee.
Wildhaus lies 5 kilometres from Alt St Johann along the valley floor, connected by PostBus services included with lift passes. Nesslau municipality encompasses both Unterwasser and Alt St Johann within a merged administrative unit created in 2013. The area maintains authentic Toggenburg culture, with Wildhaus notable as reformer Ulrich Zwingli's birthplace in 1484. Traditional mountain restaurants like Berggasthaus Stöfeli and facilities at Iltios serve regional specialities alongside standard mountain fare.
Road access follows Route 16 through the Toggenburg valley from Wattwil, continuing southwest from St Gallen. Driving time from Zurich measures approximately 1 hour 15 minutes covering 95 kilometres via the A1 motorway to Wattwil, then secondary roads through the valley. From Basel, expect 2 hours over 179 kilometres. St Gallen lies roughly one hour northeast, providing the nearest major city access. Free parking operates at Unterwasser valley station.
Zurich Airport sits 90 kilometres distant with 90-minute transfer times by road. St Gallen-Altenrhein Airport lies 20 kilometres from St Gallen city, roughly 50 kilometres from the resort. Train connections reach Nesslau-Neu St Johann station via the S2 service on the Bodensee-Toggenburg railway from St Gallen, with PostBus route 790 continuing to Unterwasser valley station in approximately 10 minutes. Total journey from Zurich by public transport requires roughly 2 hours with changes at Wattwil. The Voralpen-Express offers scenic routing from St Gallen via Rapperswil, though transfers remain necessary for final valley access.

FIS Weighs Holding World Championships in Almost Every Winter, Starting 2032
The International Ski and Snowboard Federation is looking at a major shake-up to its title events calendar. From 2032, World Championships could run not just in odd-numbered years but in every non-Olympic winter too, effectively putting a global title event on the calendar almost every season.

Mount Buller Becomes Latest Australian Resort to Call Time Early on 2026
Mount Buller closes out its 2026 season this Sunday, joining Falls Creek, Hotham and Charlotte Pass in a cluster of closures landing almost simultaneously and roughly a month ahead of schedule. The culprit is stark: Spencers Creek's benchmark snow depth hit 31.2cm on 3 September, just 18% of the 73-year average and an all-time low for this point in the season. Six of Victoria and NSW's best-known resorts will have shut their lifts early within a span of about two and a half weeks.

Tremblant to Add New Timber Summit Ski Sector for 2027/28 Season
Tremblant has confirmed a major expansion of its Quebec ski area, with a new Timber Summit sector adding 62 acres of terrain, eight trails and a high-speed quad chairlift for winter 2027/28. It's part of a CAD 42.5 million investment that also includes a new beginner learning zone at Versant Soleil opening this coming season. The project has grown considerably since it was first announced back in 2020, when it carried a far smaller budget and an opening date that never eventuated.

Thredbo to Replace Ageing Gunbarrel Quad With New Six-Seat Chairlift for 2028
Thredbo Alpine Resort has confirmed plans to replace its 37-year-old Gunbarrel quad chairlift with a new six-seat Doppelmayr D-Line, targeting winter 2028. The AUD 35 million project will keep travel time roughly the same but lift capacity from 2,800 to 3,000 skiers per hour. It's part of a broader investment push that also includes doubled snowmaking capacity at Friday Flat for 2027, with the ageing Kosciuszko Express now flagged as the resort's next major lift replacement after Gunbarrel.
