The Lost Coast was a backpacking trip unlike anything I had done before! We did about 25 miles along the coast, going from sand to boulders to cliff-sides to grassy plains. Walked through a colony of seals. And there's two 4-mile sections you can only access when the tides are low. Permits are very limited to protect the area, and when I did it, I think my partner and I saw about 8 people over 3 days.
