Kayaking

There's nothing like the vast expanse of pristine waters and mangrove islands preserved by national refuges from here to Key West. The mazelike terrain can be confusing, so it's wise to hire a guide at least the first time out.

Big Pine Kayak Adventures. There's no excuse to skip a water adventure with this convenient kayak rental service, which delivers them to your lodging or anywhere between Seven Mile Bridge and Stock Island. The company, headed by The Florida Keys Paddling Guide author Bill Keogh, will rent you a kayak and then ferry you—called taxi-yakking—to remote islands with clear instructions on how to paddle back on your own. Rentals are by the half day or full day. Three-hour group kayak tours are the cheapest option and explore the mangrove forests of Great White Heron and Key Deer National Wildlife Refuges. More expensive four-hour custom tours transport you to exquisite backcountry areas teeming with wildlife. Kayak fishing charters are also popular. Paddleboard ecotours, rentals, and yoga are available. Old Wooden Bridge Fishing Camp, 1791 Bogie Dr., Big Pine Key, Florida, 33043. 305/872–7474; www.keyskayaktours.com. From $50.
