Hill 88 is a favorite walk when the Marin headlands are free from fog. Starting from Fort Cronkhite the Coastal Trail winds up to Hill 88 at 960ft, past various WWII era coastal defenses. Cross the ridge and descend down Wolf Ridge Trail and Miwok Trail to complete a 4.5 mile loop.

Having done this walk many times I would now recommend doing it counterclockwise. You get a nice flat stretch to warm up, a fairly steady climb to the top and then can enjoy the ocean views on the way down if the fog is cooperating.
