Enjoy Marin’s gorgeous summer evenings in good company. On the trail, we’ll discuss natural history and get to know the local flora and fauna. We’ll learn a little history about our abundant public lands and touch on current conservation topics. This is not a course for beginning hikers. Participants must be physically fit and capable of sustaining, without undue fatigue, a 30-minute per mile hiking pace. Hikes are typically 4 miles on uneven terrain with about 500 feet of total elevation gain.
