It’s particularly suited for travelers who want to dip their toes into scuba without a full certification process — think of it as a “try before you buy” in the world of underwater exploration.
Starting Point and Transportation
You’ll meet your guide at Puntaldia Marina, located on the left side of the harbor, under the control tower.

From the marina, you’ll cruise a quick five minutes into the Marine Protected Area, which means minimal travel time for maximum marine viewing.
The Boat and Its Comforts
The vessel is about 8 meters long and 3.5 meters wide, with an awning to shield you from the sun. Its small size (limited to 22 passengers, but typically fewer) fosters a cozy atmosphere. The boat’s ladder makes it easy to get in and out of the water, which is especially helpful for beginners or those less confident swimmers.

The activity spans roughly two hours, with the core experience being about 50 minutes at Ruja Island — a spot praised for its natural beauty and underwater clarity. Before diving, there’s a brief but essential 15-minute classroom session covering safety and basic techniques, perfect for those new to scuba or snorkeling. The goal is to keep it simple, fun, and safe, with an approximate depth of 4-5 meters, making it accessible for most.
During the sail, you’ll pass by iconic beaches like Cala Brandinchi, Lu Impostu, Salina Bamba, and Baia Salinedda. The sightseeing aspect is as much a part of the fun as the underwater glimpse itself, offering plenty of photo opportunities and scenic vistas.
The Dive and Marine Encounter
Guided by experienced instructors, you’ll don your wetsuit, mask, fins, and tank, then follow your guide into the water. Expect to see marine species native to Sardinian waters, all within a protected environment that encourages marine conservation awareness.
One reviewer noted, “We loved the way the instructor explained everything clearly and made us feel safe.” This reassurance is key to enjoying the experience fully, especially for first-timers.
Post-Dive Relaxation and Snacks
After your underwater adventure, you’ll return to the boat for a refreshing snack. The onboard offerings include gluten-free, lactose-free, and hazelnut-free chocolate cookies, hot tea, lemon, water, and cold tea — simple but thoughtful touches to rehydrate and recharge.
The boat then heads back toward Puntaldia, giving you more scenic views along the coastline. The entire experience wraps up back at the starting point.
