The cave at Little Treasure Cove sits at the northwestern end of Crystal Cove State Park. While the most common way to visit the cave is from Crystal Cove’s main entrance, hiking from Little Corona del Mar Beach provides opportunities to visit three other caves. (Parking is free, too – although limited). If tides are low – below zero – the rock scrambling required to reach the cave from the northwest is minimal, although caution should still be exercised. As with other beachside hikes that involve rock scrambling, the challenge here is not in the minimal elevation gain or distance but rather the potentially hazardous terrain.

From the corner of Ocean and Poppy, head down to the beach on the paved walkway, passing some restrooms. At Little Corona del Mar Beach, continue southeast (you can reach another sea cave by heading right or northwest; if tides are exceptionally low and you time your trip right, you may be able to visit both this cave and Little Treasure Cove). At the end of the beach, you will begin the rock scrambling,At about a quarter mile from the starting point, just opposite Arch Rock, you reach the first cave; it is shallow but tall enough to enter.

Continue southeast, past Cameo Shores Beach and to another, larger arch-shaped rock, approximately half a mile from the beginning (your exact route along the coast may vary, depending on tides and your willingness to get your feet wet). Here you will find another small cave system; you can easily crawl inside one end and out the other.

Just before Little Treasure Cove, you reach a large, jagged rock promontory. A small round cave entrance can be seen on the west side of the wall. Using this cave to pass under not only feels adventurous; it also saves you having to climb up and over the rocks, which are sharp and often wet. While the entrance to the cave may be small, it is large enough to slip through and the inside of the cave is much more spacious than would appear.

After leaving through the wider east portal, you cross through Little Treasure Cove and negotiate one last rock barrier before arriving on the beach at the northwest end of Crystal Cove State Park, where you may see visitors walking down a staircase from the bluffs above. The cave is located directly under the observation platform. The front entrance is large but the cave quickly narrows; if you decide to explore the back chamber, watch out for a low-hanging ledge of rock.

You can continue your hike by visiting the various trails of Crystal Cove State Park, but remember that the tide may be coming in at this point, making your return via the coastline more difficult.
