This route was eating me - very tough. I had new shoes (and some blisters) and weak legs. Especially the up and downs (the route starts with a climb, then a descent and this is repeated several times). When we paused at sea-level I was needing a break to say the least). We passed some people (resting) and they said it exactly right: "a killer this one".The trail goes through the 'fog' forest of the Northern part of the island - followed by a lot of panoramic views along the coastline. The last part is straight up to the village.
