Little Capistrano Bikes, a full-service and family-owned bike shop in Eastham, is smack-dab in Cape Cod Rail Trail country. They rent, repair, and sell bikes for all kinds of ages and riding abilities — including hybrid, mountain, cruiser, tandems, joggers, recumbents, kids’ bikes, trailers…you name it.
Their Wellfleet location (1446 Route 6 South) is open only in season.
Winding through undulating woodland, the 1.6-mile (one-way) Nauset Bike Trail is a quick and delightful way to get from the Salt Pond Visitor Center to Coast Guard Beach. In early spring, the boardwalk section that crosses the marsh itself may be washed out. Never ye mind: An easy detour still deposits you at the beach.
Check for National Park Service updates before you set out. In 2013, for example, the bike trail was closed in spring and fall for restoration (at a cost of $1.87 million), but open between Memorial Day and early fall.
