If you are looking for a big deep lake with clear water, Crab Lake is a great spot to look. My favorite part about Crab Lake is its meandering shoreline which makes it a great lake for paddling. Crab Lake has a low development density which is nice because you get a little extra breathing room between you and your neighbors. Another unique feature of the lake is all of the islands. Numerous small islands can be found all over the lake. The lake is incredibly scenic, it's a special lake.
Presque Isle - Pomeroy - Henry Trails - Also north of the lake, this system consists of over 100 miles of gravel roads for mountain biking.
Presque Isle / Winchester Bike Route - This paved trail system starts in Presque Isle and can very from 4 to 10 miles depending on the route you take.
Presque Isle Nature Trail - A hiking trail that winds through the forest and past some neighboring lakes. This trail is also located in Presque Isle.
Catherine Wolter Wilderness Area - A hiking/skiing/snowshoe trail of varying lengths located northeast of Crab Lake. Trails wind through a huge wilderness area and around many small lakes.
Van Vliet Hemlocks - This trail system is just west of Crab Lake and loops along 1.5 miles of undeveloped shoreline and through old growth hardwood and hemlock forests.
