Grimentz/Zinal occupies the upper Val d'Anniviers, a side valley branching south from the Rhône near Sierre in canton Valais, southwest Switzerland. Grimentz sits at 1,572 metres on the western fork, whilst Zinal at 1,675 metres lies 11 kilometres southeast up the main valley beneath the Imperial Crown massif. The valley extends 30 kilometres from the Rhône, narrowing as it climbs through traditional Valaisan hamlets including Vissoie at 1,200 metres, where the road splits toward both resort villages. Surrounding peaks include five 4,000-metre summits forming an alpine amphitheatre above Zinal.

Sierre lies 27 kilometres north via winding mountain roads, serving as the valley's transport hub at 533 metres in the Rhône corridor. From Sierre, the route climbs 16 kilometres to Vissoie through switchbacks and narrow sections carved into steep valley walls. Beyond Vissoie, roads diverge - 7 kilometres west to Grimentz or 11 kilometres south to Zinal. The journey from Sierre takes 35-45 minutes by car or PostBus, with road conditions requiring winter tyres November through April. Other Val d'Anniviers villages include St-Luc, Chandolin and Vercorin, accessible via separate forks from the main valley road.

Road access from Geneva follows the A9 motorway east through the Rhône valley to the Sierre-Ouest exit, then Route 9 into Val d'Anniviers. The 185-kilometre drive takes 2 hours to Vissoie under normal conditions, adding 15-20 minutes to reach either village. From Zurich, the 260-kilometre route via Bern and the Lötschberg takes 3.5-4 hours. Roads narrow considerably above Sierre, with buses using both lanes on tight switchbacks. Parking exists at both village lift stations, with Zinal charging daily fees whilst Grimentz offers free spaces near the Bendolla gondola.

Geneva Airport sits 185 kilometres west, with hourly direct trains to Sierre/Siders taking 2 hours 15 minutes. Zurich Airport lies 260 kilometres northeast, requiring train changes via Bern for a 3.5-hour journey. From Sierre station, PostBus route 451 serves Vissoie every hour, requiring a change to routes toward Grimentz or Zinal with journey times totalling 45-60 minutes. Free ski buses circulate between Val d'Anniviers resorts during winter, though services to outer villages run infrequently. Private transfer operators including Taxi Anniviers serve both airports, whilst car rental desks operate at Geneva and Zurich terminals.
