Review: No Name Ridge Trail actually goes through two parks - depending on which end you start at. If you start from the north end, at Ridge Park/Trail marker post #9, you are in Laguna Canyon Wilderness Park. If however, you begin at the south end, near the Pacific Ocean, you're in Crystal Cove State Park.
And just to add to the confusion, the park maps list the first 0.6 miles of the south end as "No Dogs" trail, when the first sign you see, says "No Name Ridge" trail. No Name begins as a long, slow climb, which then has a couple of steep climbs and descents, before a final, more drawn out climb to Ridge Park. The trail is mostly double track/fire road, although there's nothing too technical, it can get rutted, a little rocky and sandy/dusty, but mainly the climbs can give you a good workout - especially in the warmer summer weather.
