4. Bend, Ore.
An outdoor sports mecca in the eastern — and far less rainy — half of Oregon, Bend also offers plenty of opportunities to bond with friends over a well-made beer or meal. Not only does Bend have an unusually high number of places to eat (it ranks as one of America's most restaurant-crazed cities based on eateries per capita), it might well be the country's capital of quality beer, with an estimated one brewpub, microbrewery, nanobrewery or craft brewery for every 9,111 residents.
5. Lexington, Ky.
If you like the idea of a cycling-focused trip, this capital of Bluegrass Country is a great below-the-radar choice. The rolling hills surrounding Lexington are famed for their estate-like horse farms, but less well known are the gorgeous, uncrowded byways that lace the region and offer wonderful beginner-to-intermediate cycling. For non-biking diversions, indulge in bourbon tasting at a distillery, tour a horse farm or spend a day watching top American ponies run at venerable Keeneland racetrack.
6. Fort Lauderdale, Fla.
When you're done lolling on Fort Lauderdale's miles of sandy beaches, consider an airboat tour of the Everglades or a visit to the International Swimming Hall of Fame. Better yet, sign on for a deep-sea fishing charter down at the port. Depending on the time of year, it's possible that you and the guys might land marlin, tuna or swordfish.
7. Las Vegas
Forget the image of carousing bachelor parties: Vegas has become a serious destination for mature, active men (and women, of course). Golf courses and tennis courts abound, there's excellent hiking in beautiful Red Rock Canyon, and a new bike trail makes a 35-mile loop through dramatic desert landscape outside town. You'll eat well here, whether at celebrity chef tables or excellent Asian restaurants away from the Strip. Looking to relax? Book yourselves massages and other treatments at the Bathhouse at the Hotel at Mandalay Bay, one of the rare spas that draw as many male as female clients.
