Biking, Walking, Jogging & In-Line Skating 

On Sanibel, paved bike paths run alongside most roads, including the length of Periwinkle Way and along Sanibel-Captiva Road to Blind Pass, making the island a paradise for cyclists, walkers, joggers, and in-line skaters. You can also walk or bike the 5-mile, one-way nature trail through the J. N. "Ding" Darling National Wildlife Refuge. There are no bike paths on Captiva, where trees next to the narrow roads can make for dangerous riding.

The chamber of commerce's visitor center has bike maps, as do Sanibel's rental outlets: Finnimore's Cycle Shop, 2353 Periwinkle Way (tel. 239/472-5577; www.finnimores.com); Billy's Rentals, 1470 Periwinkle Way (tel. 239/472-5248; www.sanibelsegway.com); and Tarpon Bay Explorers, at the north end of Tarpon Bay Road (tel. 239/472-8900; www.tarponbayexplorers).
