there are float tube sections so check out the map at the shack. also you are required to sign in at the shack. the map also shows parking and access points on the preserves property. in addition to the preserve, there are other sections open that are downstream from the preserve, look for the sign on rt 20. there is also a general store on 20 with a great map and a very helpful clerk that volunteers at the preserve. good luck and have fun.
