Scotland Highlands & Islands Hike, $1,899 ($400)
Heather-covered moors, dramatic cliffs, picturesque villages, and historic castles, such as Eilean Donan Castle, form the backdrop for this seven-night hiking trip. Skye, an island in the Hebrides, is a standout. Accommodations are in local hotels, and transfers to and from the Inverness train station, luggage transportation, guides, and nearly all meals are included. When: Sept. 15, Sept. 23.

Provence Cycle, $2,099 ($400 savings)
By night you'll sample fine wines and stay in modest country hotels, and by day you'll bike along the scenic, sleepy roads of the Vaucluse and Drôme areas in much-loved Provence (expect to clock at least 30 miles daily). The seven-night package includes bicycles, vehicle support, luggage transportation, wine tasting, and some meals. When: Sept. 22, Oct. 13.

Kilimanjaro Climb & Safari, $3,999 ($500 savings)
The most ambitious of these REI adventures entails a 14-day trip to Tanzania, where a team of African guides will lead a climb along the "strenuous but nontechnical" Marangu route towards the 19,340-foot summit of Mount Kilimanjaro. Afterwards, go on safari at the Ngorongoro Crater and Serengeti National Park. Lodging is split between mountain huts (five nights), lodges and hotels (five nights), and camping (three nights). Camping gear, taxes, transfers, and virtually all meals are included. When: Nov. 3, Dec. 3.
