There is always something to explore with ACES across the Roaring Fork Valley. Naturalist-guided aspen hiking tours, snowshoe adventures, and ski tours get you out into the stunning landscapes around the area, while birding walks, birds of prey encounters, wildlife programs, and astronomy events offer a deeper look at the natural world all around us. Families can dive in through kids’ camps and hands-on field programs, and adults can expand their knowledge through environmental education classes, evening lectures, and speaker series. Held at Rock Bottom Ranch, Toklat, Hallam Lake, and other iconic spots throughout the valley, our activities and events run year-round and are designed for all ages and experience levels.
