If you’re someone who loves the idea of exploring underwater landscapes without diving into a full-blown certification course, this Sesimbra Double Dive experience could be just what you need. Offered by Mega Dive, this tour promises a chance to see the incredible marine life of one of Portugal’s most popular underwater spots, Parque Marinho Professor Luiz Saldanha. It’s a great way to enjoy the ocean, whether you’re a seasoned diver or a complete beginner eager to get a taste of the underwater world.
What truly caught our attention about this tour are two things: first, the fact that it caters to divers of all certification levels, making it accessible for almost everyone with an interest in exploring the sea. Second, the combination of boat rides along the scenic coastline with chances of spotting dolphins adds a memorable element to the day.

Why Is This Experience Special?
The highlight is diving in a marine reserve, which generally means clearer water, healthier ecosystems, and more diverse marine life. The boat trip along Sesimbra’s stunning coastline is also a major plus — expect to take in the high cliffs and rugged scenery that frame this part of Portugal. Sometimes, if luck’s on your side, you might see dolphins playfully swimming alongside the boat, adding that extra wow factor to your day.
The Itinerary Breakdown: What’s In Store?
Start at Megadive Diving Center — this is your meeting point, where everything begins with a safety briefing. This initial 30-minute talk is crucial, especially if you’re new to diving or snorkeling, as it covers essential safety info and what to expect.
Next, you’ll hop aboard a speedboat for about 20 minutes, cruising along the coast to reach the marine reserve. The boat ride itself is a treat — the views of Sesimbra’s cliffs and coastline are stunning, and there’s always the chance to glimpse some playful dolphins.
Once at the dive site, you’ll spend roughly an hour snorkeling or diving. The first stop, at CV7Q+XV, is a marine life viewing area where you can watch fish and other sea creatures glide past as you snorkel. You’ll then board the speedboat again for the 20-minute trip to the second snorkeling spot at CR6Q+WV, where you’ll enjoy another hour of marine exploration.
Throughout the day, the guide will provide insights, highlight interesting marine species, and ensure everyone feels comfortable.
What’s Not to Love?
While the itinerary seems straightforward, it’s a full 4-hour commitment, which can be tiring for some, especially if you’re not used to water activities. Also, the tour doesn’t include hotel pickup, so you’ll need to organize your transportation to Megadive.

The tour price of $148 per person covers a lot of essentials: full gear (mask, fins, wetsuit if needed), the briefing, a boat ride, water, a traditional Portuguese sweet cookie, hot showers, and towels afterward. These inclusions make the experience feel generous and well-organized.
However, it’s worth noting what’s not included — you’ll need to handle your own transportation to the starting point unless you book an additional transfer. Food and drinks aren’t included, so plan to bring some snacks if you get hungry later. If you want to take photos, you can arrange to pay extra for a dedicated photo service.
