Rafting, Biking, and Kayaking in the Rockies

Calories burned: Up to 7,400 over five days

Call to action: If one sport in one destination sounds too easy, join up with ROW Adventures to tackle the Bitterroot Bonanza, a five-day, three-sport festival of fatigue through Washington, Idaho, and Montana. Type A's will pedal 95 miles through forests, past marshes, and across dizzying railroad trestles, then kayak on Lake Coeur d'Alene and raft the Class III Clark Fork River. (Type A–plus? Opt for the 14-mile kayak paddle through the white water.) While a full-body workout is guaranteed, the intensity is only intermediate-level, and the journey's not all hard-core: Guides on this family-friendly jaunt plan stops for kids' games and ice-cream cones, and there's a sag wagon in case your legs and lungs give out. At night, you can either flop into a hotel bed and refuel at restaurants, or, for more gasps of that Rocky Mountain air, camp out and tuck into dinner around the fire.

The warm-up: Wilderness lovers should be comfortable biking up to 37 miles per day; no kayaking or rafting experience is necessary. The trip is suitable for kiddies age 8 and up (a guide will shuttle them past the more strenuous stretches and keep them entertained with activities).

When to go: Departures are in July and August; the trip starts and ends in Spokane, Wash.

Camping option, $1,395 per person, including all camping gear; hotel option, $1,595 per person
