Channel Islands National Park
The Channel Islands National Parks is reportedly the least visited national park in the country. It could simply be because it’s quite remote. It’s 70 miles north of L.A. or an80-minute ferry ride out of Ventura Harbor.
Highlights include beautiful beaches, kayaking, canyons and valleys for hiking, and striking cliff faces. You can explore sea caves on Santa Cruz Island. You can also go snorkeling through the verdant kelp forest and share a bag lunch with tiny island foxes.
