Activity Notes

We will meet at Reflection Lake and hike approximately 1,600' to the base of the climb. Castle Peak will involve a single pitch of low 5th class rock with fixed line travel and a short rappel from the summit. If we have the time and motivation, we will also scramble up to Pinnacle Peak before hiking back to our cars. This is a popular route with excellent views of Mt. Rainier and the Tatoosh Range.

IAC, BCEP, and FM101 graduates qualify for this climb.
