The Graves is a combined natural and artificial reef site located in the United States. Divers can explore depths ranging from 6 to 21 metres, where the structure supports a variety of temperate marine life and invertebrates. The site is suited for intermediate divers due to moderate currents, surge, and variable visibility between 5 and 10 metres. Water temperatures are cold, fluctuating between 3 and 12 degrees Celsius throughout the year, necessitating appropriate thermal protection. Access is by boat only, and guided tours are available to assist with navigating the site layout and current patterns. Divers must remain vigilant regarding boat traffic and use a surface marker buoy during ascent.

The City of Portland is a wreck site located in the United States, resting at depths between 1 and 12 metres. This site is accessible only by boat and is suited for intermediate divers due to the presence of strong currents. Visibility typically ranges from 5 to 10 metres. Water temperatures are cold, fluctuating between 3C and 14C throughout the year, necessitating the use of a drysuit or thick wetsuit. Divers should maintain contact with the boat and follow guide instructions during descent and ascent. Careful timing around slack water is recommended to manage the current effectively.

The Irvington is a shallow wreck site located in the United States, resting at a uniform depth of 2 metres. This site is suitable for beginner divers, though boat access is required to reach the location. Divers should be prepared for moderate currents and variable visibility ranging from 5 to 10 metres. Water temperatures are cold, fluctuating between 4C and 17C throughout the year, necessitating the use of a drysuit or a thick wetsuit. Due to the shallow depth and potential for boat traffic in the area, divers must monitor their surroundings closely and maintain awareness during ascents.

The F C Pendleton is a wreck dive located in the United States, offering depths between 2 and 30 metres. This site is suitable for intermediate divers and requires boat access. Conditions are characterised by mild currents and visibility ranging from 5 to 15 metres. Water temperatures remain cold throughout the year, fluctuating between 2 and 12 degrees Celsius, necessitating appropriate thermal protection. Divers should exercise caution regarding surge and swell, particularly in shallower sections of the wreck. Due to the nature of the structure, there is a risk of entanglement, and divers are advised to monitor their position closely given the variable visibility.

Kelly's Cove is a high-energy shore dive featuring a complex topography of reefs, walls, and kelp forests. Divers encounter dense anemone fields and soft corals throughout the site. Depths range from 3 to 19 metres, with an average of 12 metres. Due to the proximity of the Letete Passage, this site experiences strong currents and rip currents; it must only be attempted at low slack tide. Visibility typically ranges between 10 and 20 metres. The environment supports a variety of temperate marine life and invertebrates typical of the region. Given the water temperatures, which fluctuate between 2C and 13C, significant thermal protection is required for all divers.
