Rock climbing is an excellent method of getting in shape, overcoming a fear of heights, and exploring the inside of George Washington’s nose. Learn to scale famous landmarks with today's Groupon: for $10, you get a two-hour ClimbTime rock-climbing class at Vertex Climbing Center in Santa Rosa (a $20 value). Classes are available Saturday and Sunday, 12 p.m.–2 p.m., and Wednesday 7 p.m.–9 p.m.
The spider-like staffers at Vertex Climbing Center support customers of all climbing abilities as they scale a variety of faux rock faces. During ClimbTime classes, experienced instructors belay and handle equipment while climbers focus on mastering walls and top-of-the-mountain yodeling routines. A collection of 35-foot walls jut skyward at varying difficulties, from steeply inclined slabs to fully inverted overhangs. Following supervised climbing lessons, patrons can move on to more advanced classes or take a belay test that qualifies them to guide friends indoors and brag to retired sailors about knot-tying superiority.
