Grächen is built almost entirely around the red run. Of its 12 runs and 44 kilometres of piste, 75% are intermediate, 20% are beginner and only 5% are advanced, with no expert terrain at all. The slopes fall 1,245 metres from the 2,864-metre Seetalhorn to a village base at 1,619 metres. Five quad chairs, an eight-seat chair and five T-bars fan out from the gondola, and the village sits on a sunny plateau, which gives the area a gentle, relaxed feel that suits cruising. Four magic carpets and a snowmaking line also keep the village-level slopes dependable.

The fairy-tale gondola lifts skiers to Hannigalp at 2,114 metres, with ten themed cabins that play Brothers Grimm stories on the seven-minute ride. Drag lifts including Härdera serve the beginner slopes, and a family park adds magic carpets for learners. Above, the Seetalhorn sector is a demanding area of red pistes, and the single black is a roughly 2-kilometre run down to the Bärgji hut. Experts will tire of it quickly, but families, progressing intermediates and anyone wanting a calm, uncrowded week on groomed reds will find it hard to fault.

The 2025-26 season opened on 14 December 2025 and closes on 30 March 2026, spanning approximately 15 weeks of operation. Typical seasons run mid-December through mid-April depending on snow conditions, with the high village elevation at 1620 metres supporting reliable early-season coverage. The resort averages 4.3 metres of annual snowfall, distributed primarily between December and March, with February historically delivering peak accumulation at 47 centimetres per month. Current season totals through May 2026 reached 378 centimetres, maintaining an 80-centimetre mid-mountain base depth and strong coverage across all elevations.

Grächen benefits from its position in the driest Alpine region, sheltered by Bernese and Valais peaks that block Atlantic and Mediterranean weather systems whilst channelling föhn winds that preserve snow quality. The predominantly south-facing slopes receive abundant sunshine during the 300 annual sun days, though higher elevations above 2400 metres maintain powder longer in shaded pockets. March offers optimal spring skiing conditions with 101-centimetre average summit depths and 41 centimetres at base, combining warm temperatures with preserved snow on north-facing aspects. The resort's sunny reputation occasionally means rapid afternoon softening, favouring morning ski sessions.

January through mid-March represents prime powder season, with early February averaging 4.2 snowy days per week and 42-centimetre weekly accumulations during active cycles. December and April bookend the season with lighter snowfall averaging 20 centimetres and 10 centimetres respectively, requiring snowmaking support on lower trails. The south-facing exposure and moderate elevation cap limit deep winter cold, making Grächen comfortable for families but occasionally challenging for snow preservation during warm spells. Late-season skiing extends reliably into late March, with the home run to the village typically operating throughout given the 1620-metre base elevation.

The season opening weekend features live music on the Schnööbar terrace and ski testing opportunities, whilst the Snowspring Open-Air festival closes the season on Easter Sunday with concerts on the village square. Night skiing operates on select winter dates, and the resort hosts family-oriented events throughout the calendar rather than major competitions. Quieter periods include January outside school holidays and early March, offering uncrowded pistes and shorter lift queues. The resort publishes detailed snow reports and operates four webcams at Hannigalp, Seetalhorn, Furggen, and the village centre, providing real-time conditions monitoring.
