This post has been a week late in coming. Hiked this ~5 mile trail on a clear sunny pleasant day with the second half of the trail giving us some gorgeous views of the ocean.
I would recommend using alltrails map to find the loop in this trail.
If you want a killer workout, hike this trail clockwise. The elevation is very steep for the first couple of miles. We were hiking anti-clockwise and didn’t regret it. It’s something to see great views while you are going downhill with no huffing and puffing.
