Top notch in every aspect!
The diving was incredible- hammers on every dive (and whitetips, blacktips, Galapagos, silvertips), lots of rays, schools of jacks/snapper/grunts, frog fish, flounder, lobster, and hundreds of other types of fish. Swimming under waterfalls our playing soccer on the beach between dives...all in paradise. I can't wait to go back!

We were seriously well taken care of- friendly staff, consistently excellent food, efficiently managed dives,, and oh my, what dives! Healthy reefs teaming with life on all scales, all in the midst spectacularly beautiful location!

Unbelievable trip best staff I've ever experienced diving both live aboard and land based.
Where would one begin? My first whale shark in 30 years of diving, or maybe the dive where simultaneously we had a huge Manta ray two hammer heads three Galapagos Sharks a Large Tiger shark and a two hundred pound Tuna rolls through. Every meal was a highlight as was the entire staff perfect organization. Without question the best live aboard ive done. That starts at the top nice reflection on the Captain.

World-class diving, friendly and professional staff
The two favourite dive sites - Dirty Rock and Punta María - and the night dives has offered me a magic that i will never forget. The island is intact, true nature, the sky is full of shiny stars. On the top of this the staff is really professional and ready to serve the guest with the highest possibilities with a big smile. Lifelong experience. Thank you.

Extraordinary
The crew was super friendly and helpful. Everyday fresh and super delicious food. The dive sites were selected by the national park, therefore it can happen that you dive several times at the same site but no dive is like another. The dive guides were experienced and taking care of the divers very well.

A unique diving experince
Definitely our encounter with the dolphins, I've seen dolphins during dives before but they've never sticked around this long or come up this close before, it was amazing! Such beautiful and intelligent beings:D The big schools of hammerheads were really cool too!
