Just returned from a 9-day cruise on the Norwegian Sky. I saw tons of recommendations of the Damajagua waterfalls, and I couldn't recommend this excursion more. I was torn between booking with the cruise ship vs. Iguana Mama (recommended highly by others), and I ended up selecting the tour with Iguana Mama, which was an amazing decision! My boyfriend and I ended up being the only two who booked with Iguana Mama during our excursion day, so we had an individual tour, which was so nice! Our tour guide, Raul, was so great and fun the whole way. We ended up linking up with another tour group once we got to the falls. The hike up to the falls wasn't too bad for us (being 27 and pretty active), but we had many others walking up with us at many different ages who all seemed to do fine. We took many breaks along the way, which helped a lot. Once we got to the falls, we started with the ziplines then followed with the waterfall slides/jumps. As someone who is afraid of heights, I didn't find them too scary (but did need some words of encouragement a few times). If someone is too scared, there was always an alternative ladder to climb down. After the tour, we had a Dominican lunch (which was included with the tour) before heading back to the ship port. We still had about 1-2 hours before "all aboard", so we got to spend a bit of time at the Tiano Bay pools right near the ship that were completely free. This ended up being our favorite excursion day of our cruise, and I couldn't recommend Iguana Mama enough!
