Santa Rosa Blue Hole

This dive site, located in Santa Rosa, California, is owned by the City of Santa Rosa and requires a dive permit, which can be obtained on site for a fee of $20. During the summer season, there is also a parking fee of $10 per vehicle. The maximum depth of this dive site is 81 feet, and it is classified as an altitude dive. The water temperature remains a consistent 63-64 degrees throughout the year, so it is highly recommended to wear a 7mm wetsuit. However, a 5mm wetsuit can still be managed.

While diving at this site, you may encounter crawfish and a few goldfish that have been released into the water. It's important to note that swimmers often jump off the cliffs, which can pose a hazard for divers. Additionally, tech divers may string ropes, so caution should be exercised.

This popular dive site, known as "Blue Hole," tends to be quite busy on weekends, particularly during nice weather. Divers and dive shops from the surrounding region visit this location, either with students or simply to enjoy a dive and inspect equipment. The site provides hot showers for divers and limited classroom space for indoor instruction. It is encouraged to share the classroom space with others due to the limited availability. Please be considerate of others and keep the entry/exit steps clear. It's recommended to conduct debriefings out of the water to avoid congesting the area.

Within the site, several dive operations offer more than just open water training. They may run lines across the diameter at depths of 15-30 feet, so both you and your students need to stay alert. Moreover, there are two popular hang bars made of PVP pipe for practicing dive skills—one at 20 feet depth and another at 30 feet depth. These hang bars are in high demand among divers. For your safety, there is a descent/ascent line that takes you to a depth of 63 feet, with a safety stop bar placed at 15 feet.

The visibility at this site is 14 meters, and the maximum depth is 15 meters. Divers of all levels, from beginner to advanced, can enjoy diving here.
