A well-marked trail connects Bøur and Gásadalur, covering about 5 km each way over open moorland with significant elevation gain. The path climbs steeply out of Bøur, crosses a col with views back over Sørvágsfjørður and Tindhólmur, then descends to Gásadalur sitting above sea cliffs on the northwest tip of Vágoy.
The destination is Mulafossur waterfall, which drops from the cliff edge directly into the North Atlantic below Gásadalur. Allow 2–3 hours each way. Wear waterproof layers regardless of the forecast — conditions change fast on the exposed moorland. The trail is straightforward but boggy in places; proper walking boots are essential.
