Summary
According to the agency website: "The Otter Creek Horse Trails are a series of interlocking horse trails comprising about 65 miles. They are located on both the Independence River Wild Forest Unit of the Adirondack Forest Preserve and on the Independence River and Otter Creek State Forests on the western border of the Adirondack Park in Lewis County.
The trail system uses a series of old, sandy roads and woods trails to traverse a beautiful diverse area with the trails winding their way along spirea flats and wooded areas, accessing picturesque Adirondack ponds and following or crossing Otter, Little Otter, Beaver Meadow, Chase, Burnt and Crooked Creeks and the Independence River.
There is an Assembly Area, (Map) which is located in the Independence River State Forest. This area is basically primitive camping with no electricity, no reservation system (a first-come, first-serve basis), a trailhead register (which you should sign in on for search and rescue, and funding purposes), a trailhead parking area, 100 roofed tie stalls,3 parking areas, pavilion, two stud stalls, potable water system for the horses and bathroom with sink and toilets, but no showers. (Please note the water is shut off the day after Columbus Day (USA) weekend in October.)
Otter Creek Horse Trail system features accessible bathroom facilities and mounting platforms at the Assembly Area. In addition there are 3 accessible mounting platforms at scenic overlooks to allow users to dismount and enjoy the view. There is a newly constructed (2007) accessible picnic pavilion at the main lot with reserved parking provided."
