Nothing shakes up a tired routine like a new outdoor activity. Even if your idea of wilderness is your local park, one of these clubs will have you trekking, sailing—even kiteboarding—in no time.

Find a date at one of these 14 singles clubs from Seattle to Boston. More than 20,000 members nationwide gather regularly for white-water rafting, dancing, horseback riding, kiteboarding, and more.
> Appalachian Mountain Club (outdoors.org)
Whatever your ability level, you can hike, mountain bike, canoe, or kayak on one of this group's many excursions. The AMC has 12 chapters between Washington, D.C., and Maine and hosts outings for families and singles too.

This nonprofit offers trips geared toward women, beginners, families, and specific age groups, and has a chapter in every state. You can test your limits on an eight-hour paddling excursion or do some good on a weeklong volunteer vacation.
