The Tatoosh Range, located in the southern end of Mt. Rain-Here Nat. Park, is made up of 11 named peaks. This 3 peak link-up is one of the most popular, if only because of the easy access from the trailhead. A popular Mazamas climb, this classic alpine scramble has a round trip hike of just 4 miles and 1,700 vertical feet, and thus can be done by most climbers of moderate fitness in a reasonable day. Along with a park entrance fee, all of the Tatoosh peaks offer spectacular views of Mt. Rainier - given clear weather, naturally. This is good beginner trip and fairly close to home. Be prepared for a short rappel on Castle and possible a handline on Pinnacle, depending on your comfort level on exposed 3rd or easy 4th class rock. In early season, an ice axe can be useful. "Tatoosh" means 'nourishing breast " in the local native American language.
The Castle is a box shaped peak on the immediate E of Pinnacle Peak, often climbed in conjunction with Pinnacle and Plummer peaks. There is a short rock pitch to gain the summit. Incredible views of Mt. Rainier await on a clear day. A rope and basic rock pro can help with beginner climbers.
