Best for beginner divers, shore entry, moderate current.
Tunnel Beach on the Oregon Coast is accessed via a historic 90-foot man-made tunnel at Maxwell Point. The site features dramatic sea stacks and shallow rocky areas suitable for snorkeling, particularly within tide pools exposed at low tide. Conditions are challenging, with moderate currents, surf, and rip currents present. The water is cold year-round, ranging from 10C to 15C, requiring thermal protection for any in-water activity. Due to the presence of an overhead environment and strong currents, this site is best suited for experienced individuals, though it is rated for beginners under calm conditions. Parking and toilets are available at the location.
