Mosquera Islet is a san and rock place in the channel between Seymour and Baltra islands, and is a popular gathering site for sea lions. Diving at Mosquera and the fringing rock reef is similar to Seymour until our divers reach the large sandy bottomed platform and rock between 12 and 25 meters deep where diving excursionists can find numerous garden eels, some large Galápagos sharks plus sea lions, turtles, and eagle rays.

Diving journey starts with a 40-minute bus ride from the hotel to the Itabaca Channel. Then, a comfortable speed boat is going to take our guests to Mosquera Islet, where our divers will be amazed by unique marine wildlife at wonderful two diving spots. At the first dive spot, our guides will have briefed you as you get close to the site so that when we arrive we can gear up and go. Here, divers can relax under water and wait for the schools of magnificent eagle rays, hammerhead sharks, black and white tip reef sharks, and the occasional elusive Galápagos shark. Our guests will surface after approximately an hour dive and warm up with some hot drinks and snacks to boost our energy for round two. Usually at a second diving site, our team briefs our guests once more and you dive again to shallower depths for approximately an hour. At this place divers can find sea lions, turtles, barracudas, sting rays, eagle rays, mobula rays, Galápagos eels and a variety of reef fish, and invertebrates. Divers surface for the last time, dry off completely, have hot lunch. It is recommended to be knowledgeable that from July to December sea temperature are cooler here, from 65ºF - 75ºF (18ºC – 23ºC) with occasional thermoclines from 60ºF - 64ºF (16ºC - 18ºC). We provide with 5mm or 7mm wetsuits as well as hoods and also have some spare layers. And, January to June water temperature is up 24ºC.
