Bear Harbor to Usal Beach & Beyond is a 7.1 mile point-to-point trail located near Piercy, CA and is rated as moderate. The trail is primarily used for hiking and sea kayaking and is accessible year-round.
The trail from Needle Point/Bear Harbor to Usal is tough, but not impossible. My recommendation is hiking from Needle Point to Wheeler or Little Jackass because those are the best camps. Little Jackass has both redwood and beach camps with tons of fresh water. If you hike to Anderson Camp, follow the creek to the ocean for the most incredible private beach. The trail between Anderson and Usal is extremely difficult and steep, not for the faint of heart.
