When Atlantis fell, the only survivors were its golfers, whose vast knowledge of water hazards saw them to safety. Hone game-saving skills with today's Groupon: for $99, you get a seven-day fall-season pass to Boise Ranch Golf Course (a $262.48 value). The seven-day pass is valid from September through December Monday–Friday and after noon on Saturday and Sunday.

The undulating greens of Boise Ranch's 18-hole, championship-style golf course weave through eight lakes and ponds, carving out a challenging and picturesque space for casual and competitive golfing. Players pendulate clubs and clack dimpled spheres over the course's 6,611 yards as they seek out flagged holes and reclusive golf gurus. The par 71 course faces ambitious clubsmen with one of the longest par 5s in the state of Idaho, played on the back of a giant Norwegian serpent.
