Gather for this long weekend in the high country to explore May Lake and the surrounding summits of  Mt. Hoffman and Tuolumne Peak! You’ll begin with a one-mile hike to May Lake, your home base for the weekend. You’ll grab your day pack and follow your naturalist guide to the geographic center of the park, Mt Hoffmann. As you hike, you’ll learn about the natural and human history of the peak, weather station, and lake below. The next day, you’ll either spend the day summiting Tuolumne Peak or enjoy a relaxing day lounging by the blissful beach at May Lake, enjoying the incredible scenery overlooking Tenaya Lake, Clouds Rest, and Half Dome. On Sunday, you’ll make the short hike back to the May Lake trailhead feeling refreshed, relaxed and ready to share photos and stories from your trip with your family and friends.
