Visas & entry
A hiker's guide to Grindelwald recommends the Eiger Trail as the best reward-to-effort hike in the area: about 6km and 2-3 hours, easy to moderate difficulty, following the base of the Eiger's massive north face with views across the Lauterbrunnen Valley the whole way. Their packing list reflects the mountain conditions rather than the easy trail rating: a windproof jacket, sunglasses for intense UV at altitude, and sturdy non-slip boots, with June through October as the recommended hiking window.
