Talcott Shoal is a boat-accessible site located off Santa Cruz Island, featuring a combination of reef and wreck structures. Divers can explore depths ranging from 6 to 30 metres, with an average depth of 21 metres. Visibility is typically high, between 20 and 40 metres. The site is suited for intermediate divers due to moderate currents and potential surge. Water temperatures remain cold, consistently between 11 and 14 degrees Celsius, necessitating the use of a drysuit or a minimum 7mm wetsuit. Divers should monitor local reports for swell conditions before departure and maintain awareness of currents throughout the 50-minute dive.

Bee Rock is a diverse marine site featuring a combination of reef, wall, and pinnacle topography. Located 16 kilometres offshore from Santa Cruz Island, the site offers depths ranging from 6 to 24 metres with an average of 18 metres. Visibility is consistently 30 metres, allowing for clear observation of the underwater structure. Divers should be prepared for moderate currents, significant surge, and swell. Due to these conditions and the exposed nature of the location, boat access is required for all entries. Water temperatures remain cool, between 12 and 16 degrees Celsius, necessitating the use of a 7mm wetsuit or a drysuit for thermal protection.

Cuyler Harbor, located within Channel Islands National Park, features a reef and kelp forest environment with depths ranging from 15 to 18 metres. This site is strictly for advanced divers due to strong currents, surge, and swell that complicate navigation. Visibility varies significantly, between 10 and 30 metres. Water temperatures are cold, typically between 12 and 15 degrees Celsius, necessitating thick thermal protection. Access is by boat only, and divers must remain vigilant for boat traffic when surfacing. Given the demanding conditions, divers should plan their dives carefully around current predictions and ensure they are prepared for the physical requirements of this exposed marine environment.

San Miguel Island is the westernmost of the Channel Islands, offering a remote diving environment characterised by towering kelp forests, dramatic reefs, pinnacles, and walls. Divers can expect depths ranging from 6 to 40 metres, with an average depth of 15 metres. Conditions are variable, with visibility between 5 and 21 metres and moderate currents. Due to the exposed nature of the site, boat access is required. The water temperature typically fluctuates between 11 and 15 degrees Celsius. This site is suited for intermediate divers who are comfortable managing surge and currents. Typical dive times are approximately 50 minutes.

Wyckoff Ledge is a deep reef structure located in Channel Islands National Park, requiring boat access. The site sits at depths between 27 and 37 metres, placing it within the range of advanced recreational or decompression diving. Divers experience mild currents and visibility ranging from 10 to 30 metres. Water temperatures are cold, typically between 10 and 14C, necessitating the use of a drysuit or thick wetsuit. Due to the depth, divers must manage nitrogen narcosis risks and monitor buoyancy closely. A surface marker buoy is essential for all ascents to maintain safety from local boat traffic.

Tyler Bight is a deep reef and kelp forest site located off the coast of Santa Barbara. The topography features a significant drop, ranging from 20 metres down to 70 metres, with an average depth of 45 metres. Divers must access the site via boat charter due to the distance from shore and hazardous shore break conditions. Visibility is typically between 30 and 40 metres. The water is cold, ranging from 11 to 14 degrees Celsius, requiring thick exposure protection such as a 7mm wetsuit with hood and gloves or a drysuit. The site is suited for intermediate divers who can manage deep profiles and potential current shifts.

Johnsons Lee is a reef and kelp forest site located off Santa Cruz Island. Divers typically explore depths between 12 and 14 metres, with an average depth of 13 metres. Visibility is variable, ranging from 10 to 30 metres. The site is accessible only by boat and is suitable for intermediate divers. Water temperatures are cold, fluctuating between 12 and 16 degrees Celsius throughout the year. Divers should be prepared for strong currents and potential entanglement hazards within the kelp. The site is also open for night diving. Due to the cold water and potential for surf, appropriate thermal protection and careful boat approach planning are required.

South Point on Santa Cruz Island offers a combination of reef and kelp forest diving. The site features depths ranging from 18 to 25 metres, with an average depth of 20 metres. Visibility typically spans 10 to 30 metres, allowing for clear views of the kelp canopy. Access is strictly by boat to avoid hazardous surf and shore breaks. While currents are generally mild, they can strengthen, and the site includes overhead environments created by reef structures. Water temperatures are cold, ranging from 12 to 15 degrees Celsius, necessitating appropriate thermal protection such as a thick wetsuit or drysuit.
