I used to love Mtn Lake because of their secluded primitive camping where deer often visit and provided a quiet place away from the busy RV sites, however they gave into demand and now have overrun the primitive sites with RV hookups. Very disappointing. But they do have nice facilities, clean bath houses, and a beautiful well taken care of beach. Lots of fun things to do for those with kids.
Seneca Campground provides the best view of Seneca Rocks from a primitive campground. Quiet, very clean, love the tent platforms they have at primitive sites that guarantee a flat even surface.
