Leukerbad occupies a south-facing natural amphitheater in the Dalatal at 1411 metres elevation, where the narrow valley terminates against dramatic limestone walls rising vertically on three sides in the Valais canton of southwestern Switzerland. The village sits in the Leuk district approximately 30 kilometres north of the main Rhone Valley spine, enclosed by the Gemmi Pass massif to the north and the Torrent ridge to the west. Geological springs emerge from depths beneath surrounding peaks including the Wildstrubel, Balmhorn and Rinderhorn, producing the thermal waters that defined settlement here since Roman times. This dramatic cirque setting creates both spectacular scenery and the natural basin that concentrates Switzerland's richest thermal water sources in one compact village footprint.

The nearest significant town is Leuk at 731 metres in the Rhone Valley, positioned 15 kilometres and 25 minutes downhill via winding mountain road through Inden, with an alternative summer route via Albinen adding cultural interest. Sierre lies 30 kilometres west along the valley floor, whilst Brig sits 48 kilometres east serving as the regional rail hub. The German-speaking village maintains traditional Valais mountain character despite spa development, with the historic church dating to 1484 reconstruction and centuries-old chalets interspersed between Belle Époque hotels and modern wellness facilities. Neighbouring mountain villages Albinen at 1300 metres and Inden at 1050 metres preserve agricultural traditions and blackened-timber Valais architecture, accessed via scenic connecting roads that challenge winter drivers.

Road access from Lake Geneva follows the A9 Autoroute up the Rhone Valley to its terminus at Sierre, continuing 10 kilometres on national routes south of the Rhone River to Leuk, then climbing the winding 15-kilometre mountain road through Inden to Leukerbad. Drive time from Geneva measures 2 hours 10 minutes covering 204 kilometres, whilst Zürich requires 3 hours 20 minutes over 321 kilometres. Travellers from northern Switzerland utilise the Lötschberg tunnel car-loading train between Kandersteg and Goppenstein, reducing transit time and avoiding mountain pass crossings, with the tunnel toll running approximately CHF 31 one-way. The Leuk-Leukerbad road receives winter clearing and accommodates full-size buses, though chains may be required during heavy snowfall.

Geneva Airport at 200 kilometres and Zürich Airport at 239 kilometres serve as primary international gateways, both requiring approximately 3 hours by train following the Lötschberg tunnel route. Sion Airport lies just 52 kilometres distant with 48-minute transfers, though limited airline service makes this option impractical for most visitors. Rail passengers take frequent trains to Leuk station in the Rhone Valley, where the LLB shuttle bus departs hourly for the 30-minute, 15-kilometre climb to Leukerbad's central bus terminal near the Leukerbad Therme. Inter-Regio trains connect Geneva Airport directly to Leuk in 2 hours 25 minutes, whilst Zürich routing requires a change at Visp with total journey times of 3 hours 10 to 3 hours 30 minutes including the bus connection. The bus stop in Leukerbad serves as the village transport hub, with many hotels offering complimentary guest pickups.
