Any recommendations on where to rent bikes close to here?
There are a number of reputable bicycle rental businesses nearby, and at least two of them deliver bikes to the campground regularly.
Idle Times Bike Shop has shops on Rt 6 in both Wellfleet and Eastham and both delivers and picks up from the campground (508-255-5070). Little Capistrano Bike Shop in Wellfleet does so as well (508-255-6515). The Bike Shack at 63 Shank Painter Road in Provincetown seems to be the least expensive option allowing guests to park at their facility while riding bikes in and around P-Town.
