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.

San Luis Obispo has a beautiful downtown area. The tree lined streets are full of restaurants, cafés, and bars. It is a great place to go for a walk, people watch, or visit some wonderful boutique shops.

This packed dirt road climbs steadily up the valley, with partial shade from trees by the creek. You pass under the train tracks and get a great view of the trestle.

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.

The fire road is well maintained but has some loose sections on the way down. This is a tough climb but an absolute joy to send downhill.
