Topanga is my go-to hiking place. Plenty of trails with varied landscapes – if you want to walk inside woods with narrow curvy paths, choose Musch Trail; if you want some quick elevation then opt for Eagle Rock Trail; or if you prefer loops, you can start on one, merge on the other. There are other trails here that I want to try – Santa Ynez & Parker Mesa Overlook are on my wish-list.
Eagle Rock is a 6 mile trail on a dirt-road with moderate foot traffic.
