Of note is the San Francisquito dam site. I've been here a few times before. This time I biked the old road, which turns right just above Power Plant No. 2. It's paved, partially eroded into the canyon below, definitively closed to cars, and is a great bike ride.
In the middle of this road is the dam site, which is now some sort of official landmark. There's signage:

and an unofficial trail that goes to a big chunk of old concrete

and a small monument

There's also an official, signed trail that climbs up to an overlook of the old dam, and has lots of informational panels








There still isn't really anything remaining here to look at. Here's what's left of the dam:

Bike the old road next time you're here!
