Overall rating

Habíamos leído comentarios de gente que dice que la pasa mal porque siente frio y que es solo para hacerlo una vez. Yo soy una persona que si no hay agua caliente para bañarme NO me baño y debo decir que con los dos trajes que le ponen a uno NO se siente nada de frio. Tal vez lo unico incomodo es la mascara para la cara, pero uno tiene que escoger, o congelarse la cara o estar un poco apretado y obviamente tener la cara apretada va a ganar. Excelentes guias, dando indicaciones y consejos. Paisaje increible debajo del agua transparente de glaciar. Lo repetiría, SIN DUDA QUE SI

It was an incredible experience and something I'd never done before. We were given a full brief of what the experience would consist of, advised what to expect from the cold water and helped into our drysuits. We then walked down to the water and got in slowly and told how to swim. Swimming through Silfra was like being in another world.

It was an otherworldly experience as the views unveiling underwater are breathtaking. James our guide made sure everything went smoothly, explained everything in detail and we learned a lot about the surrounding area, the park and the lake. 10/10 would recommend!

We really enjoyed this snorkeling trip! The water was so clear and beautiful. Dory, Luis, and Eyal did an excellent job guiding us through the process — very patient, kind, and humorous! Thank you!

First time snorkeling, Our guide Kevin was very helpful and knowledgeable. He made the snorkeling trip fun!
