The hike was a challenge when we went through the trail to our camp site with our stuff because there's a lot of steep hills. However, this camp spot was really secluded and beautiful and we stayed there for 2 nights. Go swimming at the end of the trail, it feels so refreshing. If you want a beautiful secluded camp spot and you don't mind carrying stuff on your hike, this is the way to go. :)
A definite elevation gain right at the beginning and in the middle of this hike. It was a beautiful hike, and perfect in early September. There is a point at which you are on a sand dune but also in forest...so lovely. Saw a blue heron at the lake. Met no other hikers despite several hours on the trail. The several bridges on the trail were in excellent repair.
An excellent trail with diverse environments: forest, dunes, ocean and, especially, the swimmable Threemile lake with sandy bottom. It is not often that one can make a splash on the way, ponds/lakes/creeks sometimes have rocky bottom that one can injure feet in. Highly recommended.
