There are three primitive sites at Crystal cove. I've stayed at two. Both Morro locations.

Lower is a 3 mile hike with a few steep grades. 13 sites an outhouse and a decent view. This one is normally supporting several groups on weekends. There is no water. Be sure to carry enough. No power, no light.

Upper Morrow is another 20 minutes worth of hiking with 20+ spots and usually no one. People tend to stop at lower.

The park is small. The perimeter loop is under ten miles. Super bike friendly, but dosnt allow any animals.

Note that there's a $25 fee
