Full description
If you’ve always wanted an underwater diving experience but didn’t want to go scuba diving, then seaview boards are perfect for you. Join this 2-hour excursion from Lisbon out to Sesimbra and go swimming in Arrabida’s Nature Park with the aid of buoyant, see-through boards. Head to the starting point through the region’s cliffs and greenery. Once you reach the diving spot, your guide will give you a short introduction to how to use the board. You don’t need to be an experienced swimmer at all, as the board helps with buoyancy. Put on your fins and hop in the water with your seaview board. While lying on the seaview board that you propel with your fins, you can look underwater through a porthole.   Swim along the coast and admire several spots full of vibrant marine life. Spot golden grey mullet, seabass, golden fish, white and zebra seabream, and more. You also might spot the dusky group, the John Dory, or the long-snouted seahorse.

I came with an 8 year old and a 12 year old and they both loved it. Miguel, our guide, was extremly good with the boys and was present with us throughout the whole activity in the water. As a parent I enjoyed as well but especially seeing the children in such exitement. I recommend for sure!!!

This experience was amazing! Decided to do the Seaview board because my aunt was fearful of other activities (such as snorkeling) and this was a great middle ground to observe sea life! Annabelle was wonderful to us and incredibly patient. We were provided with wetsuits and fins aside from the seaview board, and Annabelle even provided extra pictures and videos taken with her go pro camera. If you’re nervous to jump into snorkeling or diving this is a great way to start.
