Crater Lake is a freshwater caldera site in the United States known for exceptional visibility ranging from 30 to 100 metres. The site features a shallow reef shelf at 4 to 6 metres before the bottom drops away into significant depths. Due to cold water temperatures, which range from 3 to 19 degrees Celsius, and a pronounced thermocline, this site is rated for advanced divers. Shore entry is available, with parking and toilets provided on site. Divers should wear adequate thermal protection, such as a drysuit or high-grade wetsuit, to manage the cold water. Always check National Park access rules, as a permit is required for diving.
