The Headlands Trails travel along the top of the coastal bluffs. Below the bluffs, the Pacific Ocean meets the land. Waves crash spectacularly against the rocks below. Fine ocean views present themselves.
The Fern Canyon Trail travels through a coastal forest. A good part of the trail follows alongside a stream. The trail will eventually come to a fork. The middle path will lead to the foot of a 36-foot high waterfall that runs most of the year. The round trip to the waterfall and back is just under 5 miles. The trail is not difficult but does steepen between the fork and the waterfall.
The waves of the Pacific Ocean pounded against California's shore and created an inland tunnel below the coastal bluffs. This tunnel encroaches inland about two hundred feet. At the end of the tunnel the earth gave way and collapsed forming a hole 100 feet across and 60 feet deep. One can look into this hole and see the ocean surging below at high tide.
