Apparently we missed 70% of the trail because the trailhead wasn’t visibly marked and the map provided by park service wasn’t much help either. We are avid hikers, for the record, and found this to be very confusing. We ended up walking on the beach for 2 miles and walking the 2 miles back to our vehicle on the bike path. This was very unpleasant. The beach was beautiful though, and extremely quiet. We found beautiful seashells and enjoyed this portion of our walk immensely.
