Reviews: Group Scenic Sea Kayaking in Cascais, Lisbon
Guest User2026-09-29
Daniel was a superb and reassuring guide and tutor where we enjoyed a very fun sea kayaking tour of the rocks and coastline around Cascais. It's advisable to bring a bottle of water, sun protector, swimming costumes/trunks, a small backpack with towel, and a change clothes and a sweater (just in case!) We met at Praia de St Marta and then went inside the Boca do Inferno at high tide. It was a superb trip in all aspects.

We were staying in Sesimbra and decided to book the kayaking trip for the day. I am really glad we did. The views were incredible and the guide was kind enough to provide restaurant recommendations.

Brilliant teacher (David) very reassuring for beginners and helped us the whole time until we were doing it ourselves. Good wetsuits provided. Would do this again if we come back to the area. Thank you!

Reviews: Lisbon: Kayaking and Snorkeling Adventure

Miguel was an excellent, knowledgeable and friendly guide - from asking for music requests in the transport to helping us get in the kayak. Along with the activity we were told facts about Lisbon and even saw and got to hold starfish, sea cucumbers and more. Excellent trip would definitely recommend booking with Miguel and co. Thanks again for a great trip.
