This trail has a closed portion, but the entire trail isn't closed. If you start at El Capitan, you can avoid the closed portion by heading down to the beach for a bit, then back up. If you start at Refugio you have much more trail. This trail is easy, and paved. Some areas you can't see the ocean due to plant growth, but there are some lovely quiet beaches along the way. A really nice way to walk a section of the Gaviota Coast.
Pro Tip: Use the bathroom before heading in either direction. Pro pro tip: A lot of the bathrooms are locked. Keep trying. It's like an Easter egg hunt!
