Tar Pits Park features some of the few natural asphalt lakes in the world. These tar pits, formed by ancient petroleum seepage, date back to the Pleistocene epoch and have preserved fossils of prehistoric creatures. Historically, the Chumash people used tar to waterproof their boats and tools. The park has been preserved and restored to its natural state, with a great path that winds throughout the grounds, popular for hiking and biking. There are several picnic tables, plenty of benches with fantastic views, a harbor seal sanctuary, and a lovely stretch of beach. Tar seeps out of the ground along the trail, beach, on the bluffs, and throughout the park and can get on your shoes. It's a good idea to bring footwear that you don't mind getting dirty when you come to explore this beautiful area.
