Best tour in Saipan - Terrific guides. Very informative. Fun swim in the grotto. Beautiful area! Safe, guides take good care of you.

Blue Cave Snorkeling - It was such a beautiful place. I'm glad I went. The guides also spoke Japanese and were very happy to be taken to Banzai Cliff and Bird Island in the end. At the end of the day, iPhone users received photos and videos from Blue Cave for 30$.

Well done Marianas Trekking - Very well looked after by Armand. who was friendly and took some great photos for me as a souvenir. The grotto itself is good fun, and certainly worth a visit. It was a little crowded so I'd recommend going early. Armand certainly gave me the space to make the most of my visit while keeping a close eye on me. Recommended

Great time at the grotto - My partner and I had a great time with Marianas trekking at the grotto. I felt very safe getting in the water over the rocks with them & we had such a fun time. Very knowledgeable and flexible. They took some great pictures of us underwater that we will treasure. Highly recommend!

A fabulous experience, thanks to a great crew, and a special place. - What a fabulous experience we had on the half-day snorkeling tour of the Blue Grotto in the capable hands of Marianas Trekking. We were a group of seven who especially appreciated the care and bonhomie from five of their crew. Jojo, via email in planning, was excellent, wisely recommending the afternoon tour as it was often less crowded, and we'd have the grotto to ourselves on this day, John blew amazing underwater bubbles for great photos, drove us around, and shared interesting bits of his life. Leo was super helpful, and Sandy too, being principal photographer/videographer. Arman helped with tech and dropped us at the ship. Everyone was simply wonderful to be with, as seems true throughout Saipan. Even the owner, Chris, took time to give us a trio of tips for our visit. The Blue Grotto is a fabulous and unique place, which I hope you too can experience. The trio of other stops at Bird Island, the Last Command Post, and Banzai Cliff were also good, adding history and culture to our tour. Lastly, big kudos to the well done theater experience, complete with popcorn, to view the photos and videos from the tour. We have superb memories, thanks to you all.

Very beautiful Grotto, a must see while you are in Saipan - Both of our guides were very patient with us and incredibly knowledgeable about the island. The Grotto was absolutely beautiful. The steps to and from the Grotto were scary but doable if you take your time.
