Cave Rock Arch is a massive sea stack located on the Southern Oregon Coast near Pistol River. The site features a natural tunnel carved through the centre of the rock formation. Divers and snorkellers can explore the base of the stack and the interior of the arch, though access is restricted to extreme low tides when surge conditions are minimal. This is an advanced site due to challenging conditions, including cold water temperatures between 10C and 12C, strong currents, rip currents, and significant surf and surge. Shore entry is required to reach this marine reef environment.

Myers Creek Beach on the Southern Oregon Coast is defined by its dramatic sea stacks and the prominent Cave Rock arch. Snorkellers can explore the base of these geological formations, which provide a unique environment for observing local marine invertebrates. Access is via a shore entry, and the site is best suited for intermediate snorkellers due to the presence of moderate currents and surf. Water temperatures are cool, ranging between 10C and 13C throughout the year. Parking is available for visitors. Given the potential for rip currents and surf, caution is advised when planning a visit to this coastal location.

Pistol River Mouth (South Unit) is a marine reef site on the Southern Oregon Coast characterised by rocky outcrops and a dynamic estuary. This site is suited for advanced divers due to challenging conditions, including cold water temperatures ranging from 10C to 12C, strong currents, rip currents, and surf. Shore entry is required, and parking is available for visitors. Snorkelling is possible but limited, with the best conditions occurring on the ocean side of the rock formations during calm summer mornings. Given the environmental hazards, this location requires careful planning and experience in temperate, high-energy marine environments.

Kissing Rock is a prominent sea stack on the Southern Oregon Coast featuring smaller surrounding rock clusters that form protected pockets at low tide. This site is suitable for beginners interested in exploring shallow kelp forests and tide pool extensions. Snorkelling occurs at depths ranging from 1 to 5 metres, with an average of 3 metres. Conditions are characterised by cold water, mild currents, and visibility between 3 and 6 metres. Hazards include surf, surge, rip currents, and low visibility. A wetsuit is strongly recommended due to the consistently cold water temperatures. Parking is available for visitors.

Secret Beach is a secluded cove located within the Samuel H. Boardman Corridor on the Southern Oregon Coast. This site features dramatic rock arches and sea stacks, providing a protected area for snorkelling at low tide. Access requires a scramble down a steep social trail from the shore. Water temperatures typically range between 10C and 13C, though the Chetco Effect can occasionally create warmer localised conditions. Due to the presence of surf, surge, rip currents, and cold water, this site is suited for intermediate snorkellers. Divers and snorkellers should also be aware of potential hazards including entanglement, jellyfish, sea urchins, and sharks.

North Jetty is a dynamic site located where the Rogue River meets the Pacific Ocean. This shore-entry location features rocky structures and an artificial reef environment. Snorkelling here is suitable for intermediate participants, with depths ranging from 1 to 6 metres. Conditions are highly tide-dependent and can be challenging, with strong currents, surf, and low visibility between 1 and 5 metres. Water temperatures remain consistently cold, between 10 and 12 degrees Celsius throughout the year. Hazards include rip currents, boat traffic, and sea urchins. Parking is available for visitors. Due to the variable conditions, careful planning is required for all water activities.
