If you’re looking for a way to beat the heat, see some stunning marine wildlife, and get a taste of Portugal’s natural beauty, this snorkeling experience in Sesimbra might be just what you need. Operated by Arrábida Experiences, this three-hour adventure takes you into the protected waters of the Prof. Luiz Saldanha Marine Reserve in Arrabida Natural Park, not far from Lisbon. It promises not just the chance to see fish and rock formations up close, but also to enjoy scenic views of the rugged coast and lush landscape that makes this area so special.
What I love about this tour is the knowledgeable guidance—guides Rudi and Tomás, in particular, are praised for their professionalism and personal touch. They know the area’s secret spots and teach useful snorkeling techniques that can help even beginners feel more confident. Plus, the calm waters of the marine reserve make for a safe and enjoyable experience — ideal for first-timers or those who simply want to relax and soak in the scenery.
One possible consideration is the water temperature—several reviews mention the water can be quite cold. While the provided equipment helps, packing a wetsuit or at least being prepared for chilly waters might be wise. Also, this activity is not suitable for children under six, pregnant women, or folks with back problems, so it’s best to be mindful of your physical condition.
This highly-rated experience offers a wonderful blend of adventure, scenery, and expert support. It’s a great choice for travelers who want a relaxed, educational, and fun way to explore Portugal’s marine life, especially if you’re drawn to scenic coastlines and underwater exploration.
