Trail Overview
This is a very sandy trail--not really deep, but very thin for long sections. Lowering your tire pressure will help the ride. Expect some dirt/gravel with some small water crossings. You can take a detour that will take you to a very isolated and beautiful beach, where you can spend a day or two and camp with no problem. It's a pretty trouble-free trail with some beautiful views and a beach along the way.
Difficulty
Most of the trail is sandy, not very deep but loose, so lowering your tire pressure will help. You may have some small water crossings and some gravel along the way.
