I had one of the best rides of my life on this trail. The views were fantastic along this old cog railway right of way, especially at the West Point Inn, were you can even stay the night if you book ahead. The surface is mostly crushed rock and dirt so it is not appropriate for road bikes with skinny tires and is very tiring since it is an almost constant uphill ride on a rough surface; but, the views and the thrill ride on the way down make up for the pain. Not for the out of shape. Watch out for speeding cyclists coming down the mountain as you make your climb.

This trail features a nice long climb and great views of the Bay Area from the top of Mt. Tam (I ride it every Sunday). It's also fun and fast going downhill. Just be sure to have shocks on your bike.
