A lovely smooth dirt road climbing up into the hills and wilderness beyond. A breathtaking landscape to cycle on, giving you a real feeling of remoteness and seclusion. You will need a treaded tire for this road with a bit more width than a road bike tire.

This is the end of Milpitas Road, northwest of here past the campground the road is closed for bike and foot traffic along the Arroyo Seco - Indians Road route. If you are planning on biking to Arroyo Seco this is a decent place to start your adventure from the south side. There is a hiking trailhead here that mirrors a similar route to Santa Lucia.

There are a host of easy doubletrack trails that take you along the hills around the reservoir, many of which are not online at this time but are easy to spot in person. You can park off of Old Creek Road for a couple bucks and explore the dramatic scenery that the reservoir has to offer.
