Whale Rock Reservoir is a 4.1 mile lightly trafficked out and back trail located near Cayucos, CA and is good for all skill levels. The trail is primarily used for hiking, walking, and trail running and is accessible from April until November.
It was a hot day but a nice hike around the reservoir. It's $2 a person and when you go in you fill out the form to hike around. Please note this is off of Old Creek Road, which is not where we were sent. And the entrance is down from the road so it's kind of hard to see. This is also 5 miles in total. We tracked it and if you go up to the right that is the longer trail to the left is like .2 miles or so. I definitely recommend wearing pants because my calves were scratched up from the plants on the trail, but not terribly bad.
