Sometimes it seems as though you have doubled back on yourself. You should see lots of mergansers, black duck, great blue heron, beaver and maybe a glimpse of mink or otter. Further upstream, the river narrows and deepens. Maple, cherry, and conifers cover the higher banks. If you don't want to spend a whole day, canoe up half the time you want to spend and then return.
High Rock makes a nice destination and a good place for lunch.
Inlet, the DEC canoe launch site, is at the end of a dirt road 3.2 mi. Inlet Road is about 3 mi. Wanakena to Cranberry Lake Put in at Wanakena and paddle downstream to explore Cranberry Lake. Stay in the marked channel to avoid submerged stumps until you reach the Ranger School. Either return, or proceed to the hamlet of Cranberry Lake.
