About This Route
The Eiger Trail, stretching 6 km from Eigergletscher station to Alpiglen in the Jungfrau region of the Swiss Alps, offers breathtaking views of the Eiger's North Face. This intermediate to advanced trail running route features around 500 meters of descent, rocky paths, and narrow ledges with exposure. Popular among trail runners for its dramatic scenery and proximity to Grindelwald, it starts at 2320 meters elevation and drops to 2040 meters. Expect technical sections with loose scree and steep gradients that demand precise footwork. According to the Swiss Alpine Club (SAC), this trail sees heavy use in summer, so start early to avoid crowds. Follow Leave No Trace principles by sticking to marked paths to prevent erosion on these fragile alpine slopes.
Safety Considerations
Sudden weather changes are a primary hazard; fog can roll in rapidly, obscuring the exposed North Face sections and increasing fall risk. Rockfall is frequent due to the Eiger's unstable cliffs, so wear a helmet and monitor for tumbling stones. Altitude sickness affects runners ascending quickly, so acclimate in Grindelwald first and hydrate aggressively. Steep drop-offs require trekking poles for stability. Check MeteoSwiss forecasts and SAC trail reports daily. Cow herds can block paths; yield right of way as per Swiss alpine etiquette. In thunderstorms, descend immediately to avoid lightning strikes on metal gear.
Essential Gear
Pack Salomon Speedcross trail shoes for superior grip on scree, Black Diamond trekking poles, a lightweight Petzl helmet, CamelBak hydration vest with 2L capacity, Garmin inReach satellite communicator, REI Co-op rain shell, sun hat, and high-energy gels. Carry a first-aid kit with blister treatments and altitude meds like Diamox.
