Good adventure for a day or two. Lots to do on the northwest end of the island. Here you will find remote bouldering and cragging opportunities, as well as other flavors of fun. Well worth the drive. Fill up the tank first. Watch out for the flamingos, goats, and iguanas.
I know . . . this description is vague, but the connoisseurs usually like that. See the photos for more info.
Head north on either of the 2 roads. The coastal one-way is more scenic. Hang a left in Rincon.
