Route: The south side of the lakes and rivers is the recommended side to hike on. No major obstacles will be encountered. Stay near the lakeshore and near the connecting river if possible. Most heavier brush patches can be avoided this way. Hiking along the lake also allows better views. Camping and fishing opportunities are prevalent.
