They do not make it easy to find the Rancho Del Oso Nature and Historic Center. There is only one small sign along highway 1, which if you see and manage to pull off the road, you will still need to follow the small dirt road around a bend and up a hill to the center. This is too bad, because the center has a lot to offer. They are only open on weekends, but you can come and hike their trails anytime. There is a self-guided nature tour, so stop at the center and pick up a pamphlet.
