Yes, several sites are graded for beginners. Mar Menuda is a shore-entry site offering reef, drop-off and cave features across a wide depth range, making it a practical first dive in the area. Secallins is another accessible option, combining reef and seagrass in moderate depths. Intermediate and advanced sites such as Port Salvi and Sa Bauma are there for those ready to progress.
Both options are available depending on the site. Mar Menuda is one of the most popular shore-entry dives, reached directly from the beach. Cala de Port Salvi also offers shore access alongside boat access. The deeper and more exposed sites, including Port Salvi and Sa Bauma, require a boat, and several operators based in Tossa de Mar run guided trips to these locations.
Tossa de Mar offers a good spread of underwater terrain. Caves and canyon features at Port Salvi reward exploratory diving, while the walls at Cala de Port Salvi suit those who enjoy vertical topography. Seagrass beds at sites like Secallins and Cala de Port Salvi shift the focus toward smaller, slower-moving life including Seahorse and Mediterranean Hermit Crab. The variety means even repeated visits tend to feel different depending on the site chosen.
