"This 190-acre zoological, botanical, and geological nature preserve at the base of the beautiful San Gabriel Mountains has miles of trails and a 40-foot waterfall that cascades into a wide pool, which is particularly refreshing on a warm spring day. While Angelenos are known to flock to some of the more photogenic, highly trafficked hikes (looking at you Runyon Canyon and Griffith Park ), this hike is a real treat, especially after a rain when the waterfalls are running. Take note: due to the pandemic, this trail currently requires a reservation." - Maxwell Williams, Krista Simmons
