Top Guam Underground Tours

This tour was SO worth it. The cave alone is breathtaking, but Wawa really made it unforgettable—fun, knowledgeable, and honestly an amazing photographer too. Having a guide makes all the difference. I’d do this again in a heartbeat.

Excellent!!! Wawa was a wonderful and well experienced guide;. He made this trip safe and fun for us. All of the staffs were very friendly and kind.

I was raised on Guam and left in the 80s and never had a chance to visit Pagat Cave. My husband, son, and I were visiting for a couple of weeks and had no one available to help us get to the cave, so we went with Guam Adventures and we are happy we did. Our hiking guide, Rocco, was friendly, caring, informative, and entertaining. Some information future hikers might find helpful: Everyone will meet at the Guam Adventures office which is right by the beach, outside the back of the Hilton Hotel. If you’re driving yourself, you can park in the Hilton’s parking garage without paying a fee or needing a pass (as of June 2024). The entire activity is listed as taking 3-4 hours. We finished under four hours. Bring a hat, gloves, sunglasses, sunscreen, and use shoes with traction… Since the cave is water-filled, wear swimwear under your clothes, bring a towel, water shoes, and a waterproof phone case. Most importantly bring cold water (at least two bottles/person). Water bottles and snacks are provided before the hike. (Our snacks were cookies and granola bars.) I brought some water which I partially froze. Much of the hike will be shaded but it’s strenuous and hot. And when you’re out in direct sunshine, it’s extra hot. The hike is listed as challenging and it is! Unless you’re in good shape and exercise regularly, don’t do it. There are many steep areas, jagged rocks and slippery areas. Gloves will help with holding on. I didn’t bring gloves but Rocco loaned me a pair. I’ve done challenging trails in the mainland, but this was harder, in my opinion. I wore jeans on the way in and was thankful that I didn’t get scratched up, but on the way out, I wore shorts, and I preferred that since it was cooler. Pagat Cave is pitch black, but the tour guide will bring lighting. There were other hikers in the cave and several brought their own lighting, which helped brighten the cave. The cave was awesome and unforgettable. I don’t know how to swim, so I just waded in the cool water. At the end you’ll be given the opportunity to buy pictures that were taken by the hiking guide. You can include a tip for your hiking guide with your purchase or just bring cash to tip. Note: There’s no bathroom/porta-potty Thank you, Rocco, for encouraging me to enter the cave when I was just gonna wait by the entrance!

Definitely recommend this hiking experience! From the moment we arrived, staff was attentive, provided space to store our items, as well as back packs, life jacket, water and snacks. You will be entering the fresh water cave so be prepared to get wet. The hike itself is short but can be technical. If you have some work gloves, they help with navigating the terrain and the jagged rocks. If your water shoes are not sturdy, you can carry them in your backpack and change before you get into the water. The views on the cliff are spectacular. Our driver Jojo and guide Rico were awesome. They were professional, engaging, patient, and helpful. Rico took plenty of pictures during the hike and you have the opportunity to purchase them for a small fee. You won’t regret seeing Guam in this excursion! So worth it!
