Las Vegas is home to several indoor rock climbing gyms including the Red Rock Climbing Gym designed by two of the best climbers in the world. Here they offer both top-rope and lead climbing on over 8,000 square feet of climbing walls. We took our kids to climb here on a Sunday during the kids 2 hour climb time. A kid's day pass is just $10.00. They let our kids climb in their own shoes, otherwise we would have had to rent shoes for $5.00. Our youngest was too short to climb.
