I went scuba diving for the first time and it was truly incredible! I was so nervous, but Lydia(the best instructor ever) helped me through the entire dive and it was one of the best experiences I’ve ever had! Could not recommend more!!

We did the open water training. We enjoyed a lot the place to start (nice restaurant and bar by the beach with amazing sunset) and all the staff was great. Most importantly Ana (our teacher) was very thoughtful, knowledgeable, we felt super safe diving and we had a lot of fun 😁 I absolutely recommend to go there 👌🏼
