My boyfriend and I had an amazing time at this attraction, it’s unique and exciting. Best if you know how to swim and can walk in uneven underwater floors but not a must. Our tour guide was Roberto and he did an phenomenal job making sure he explains all the details of what we were looking at and ensuring everyone was taken care of but at the same time making it an experience we can’t forget. Tha i you Roberto!!!
This tour was super COOL! Swimming in the cave was such a fun experience and the buffet lunch was delicious, very authentic food! We purchased the pictures and they were worth it, they looked great. Really enjoyed this tour and would highly recommend!
Had an excellent time. This was our second visit. The first in 2013. Since then, much improvement in the Experience. Our guide Daniel Yul was very informative and helpful for our group of 8 adults. It is an amazing experience swimming in and underwater cave. The pictures taken by the staff photographers were stunning.
We had a great time doing this experience. It was serious spelunking -- wetsuits, a little bit of swimming, and all in a very dark cavern. We had headlamps so it wasn't scary though my 8 year old son did get a little freaked out when we turned them off at one point. I've never done anything like this so definitely it's an experience I won't forget. The tour is long 45 minutes? 1 hour? and time seemed to lose meaning down in the caverns. We couldn't bring our own phones/cameras so if you want photos, you have to pay for them. A photographer comes along with you and takes a lot of photos. The photos are very expensive so be prepared to pay 100 if you want your whole roll.
