The Subway Bouldering

Park at a big antenna on the right (northeast) side of 158, five minutes (2.6 miles) after driving past Robber's Roost. The big antenna has a small pullout that fits three or four cars. If this lot is full, turn around park along the side of the wide dirt road just before the pullout (Archery Range Rd) and walk the extra minute down to the antenna.

Walk past the antenna on the left side of the fence, picking up a trail heading northeast (slightly right), then north (slightly left) before dropping into a wash. Go right and follow the wash northeast until, just after it narrows, it opens up a bit, and there is a dirt trail that goes immediately left (about 100 feet before this obvious trail, there is a faint social trail on the left that does not lead anywhere, so don't be fooled by it). Hike up and slightly right towards a small ridge with some cacti, and then take a hard left through some trees to a steep downhill trail with a couple switchbacks. The Main Cave of The Subway will be to your right when the trail levels out at its low point.

The trail descends 300ft and takes less than 10 minutes to get down and slightly longer to get back.
