I've been doing this ride since the late 80's back before the stairs were in place and you could ride the whole thing. There were some natural 'landscape adjustments' sometime back in the mid 90's that necessitated the stairs. I start at Cronkite Beach and simply follow the paved road past the parking lot towards the beach. There's a gate here to prevent vehicle access. It's a good climb for at least 1/2 mile until you tee into another old paved road. Take a left and an immediate right onto the singletrack. This singletrack climbs up to the aforementioned stairs that require a hike. Another section above the stairs will probably also require a hike. All this used to be part of a continuous paved and ridable road. It used to be a better ride. From this point to the top it's all paved. It's just an out and back climb/descent. The cool thing is the final ascent required to crest the hill. It's short, steep and a perfect work/reward scenario! It's worth the climb just to check the view from the top and the old military base. There are many brick buildings and platforms.

Recommended Route:
Take Sausalito exit just north of GG bridge. Go to Conzelman Road on west side of bridge and climb up into the Marin headlands. Arrive at intersection with McCullough Road. If on bike, take the fire road between the 2. Go to bottom and go left towards ocean when you hit the paved road. Stay on this road until you reach the gate and proceed as described above. If in car, easiest is to go right on McCullough and proceed toward Cronkite Beach and the gate.

this is not a climb for novices. there are two or three particularly gut wrenching technical sections during the climb which may or may not keep even the most experienced riders off the bike. stay on the trail, as there is poison oak EVERYWHERE in the underbrush. this climb also includes a nice steep stairway which you must carry your bike up which is followed immediately by a short, steep loose climb that will give your anerobic fitness a true test. once you reach the top 9after a grueling steep road climb) you will be reqwarded at the top of hill 88 with sweeping views of the bay area and the pacific ocean. (we call this place Ice Station Zebra because it is very windy and cold most of the time) hill 88 is actually and old abandoned nike missle station, a decaying remnant of the cold war. riders can connect hill 88 to the miwok stables by using the wolf ridge fire road to connect to miwok/old springs, but keep in mind that the wolf ridge fire road is CLOSED TO MOUNTAIN BIKES for no apparent reason, so ride down wolf ridge at your own risk. don't bring any novice riders along for the wolf ridge descent either, as it is steep, looose and riddled with huge waterbars. this is an ideal night ride. Ice Station Zebra/Hill 88 merits my four star rating, due to its difficulty, the view at the top and connectability with other marin headlands rides.

Recommended Route:
use the directions i've provided on my trail listing. my apologies for posting this trail three times, MTBR must not like the hill 88 name. the trail leading up to hill 88 is legal for mountain bikes, the wolf ridge descent from the top is not, but we ride on it anyway.
