Parking on the National Trust Car Park on the edge of Buttermere Lane, walk across the foot of the lake. Upon reaching Burness Wood the path begins to climb, once you are above the treeline there are wonderful views over Buttermere.
It can be quite cool on the tops, so it’s worth packing hats and gloves. The ridge walk begins at High Stile leading on to High Crag, with spectacular views of the surrounding rocky scenery and valleys below.
The descent down Gamlin End is somewhat steep and jarring. A pathway (easily missed) leads to Scarth Gap Pass and back to Buttermere. By following the trail along the back shore you can look back toward the fells you have just climbed.
