Sea Cave at Corona Del Mar. "The sea caves of Corona Del Mar are a great way to beat the heat. If you want to check out some interesting coastal geology without having to go all the way down to Dana Point, this is a good hike to do. It is a little trickier than the Dana Point trip, however, so if you don’t have a lot of experience climbing over slippery rocks and with beach hiking, definitely make sure you go at low tide..."
