I was anxious but it was a dream made a reality Five stars Great team and excellent professionals A good act to Gonçalo who always accompanied me in this adventure
Muito Obrigado pelas suas palavras. Estamos felizes que tenha gostado. Mega Dive Team
This was undoubtedly a wonderful and unforgettable experience! The staff is super friendly and helped us have the best baptism possible, explaining every step of the diving. The boat trip alone was very beautiful and gave us to see beautiful landmarks like the mule rock! All the girls, some more afraid than others, were amazed at the moment and we only have to thank Ana for having accelerated the marking and all the thousands of doubts we had before the diving, the instructors Maria, Miguel for having delivered the experience with humor, professionalism and relaxation and to Diogo (who also took underwater photos), but also to Mr. Henry!!! It was a morning that we will always remember with great affection.
Ola Sara / Iris Desde já agradecemos as vossas palavras! Ainda bem que gostaram e á agora, vocês foram 5*, grupo bem animado e super disponiveis a novas experiências! Um muito obrigado de toda a equipa!
I loved the experience! I had some anxiety before starting the diving, but instructor Paulo was 5 stars, with calm and patience helped me overcome my fears and managed to make one of the best adventures of life! I'm already thinking about marking next time with friends 😄
Bom Dia Desde ja agradecemos as amaveis palavres, ficamos felizes de que tudo correu bem! Estamos cá apra a proxima aventura! Mega Dive Team
Staff always attentive, available and warm in the guidance and facilitation of the dive experience. It was top top top!!!
The Mega Dive center was recommended to me by a friend. What an excellent decision! Instructor Ana Claudia provided me with an amazing diving baptism in the waters off Sesimbra... so much beautiful thing we saw! In addition the center has excellent conditions and also sell top equipment from various reference brands. I highly recommend!
I offered this experience to my nephews and made it a matter to accompany them, the instructors were super attentive and professional. It was a good afternoon and on the return we still saw dolphins. Unforgettable!
The whole team was spectacular, extremely professional. The fauna and flora observed during the baptism is simply amazing. Repeat!
A Mega Dive agradece em nome de toda a equipa. Esperamos por vocês brevemente em mais experiências nossas.

Really pleased we chose Mega Dive for this experience. A comprehensive safety briefing. Lovely boat…..seeing dolphins was an added bonus. We were 2:1 with an instructor which gave added confidence. The dive was long enough to really settle in to the technique and take in the marine life. Would highly recommend!
