What To Expect

Make your way to the Caribe Hilton in San Juan to begin your sea trek experience.

Meet your professional sea trek guides on the hotel's private beach. Get a safety briefing and orientation, including hand signals for communicating underwater and a full description of what you can expect. Sea trekking is a great way to explore underwater if you have glasses or contacts, as your head will stay completely dry and you can avoid the hassles of salt water in your eyes or blurred vision. Children ages 8 and over are welcome to participate, provided they weight 80 lb (36kg) or more.

Once you're ready to begin, wade slowly into the shallow end of the calm, protected cove. Accompanied by your instructor, spend time underwater, moving at your own pace. Walk toward the deep end of the cove, where you can see squid, octopus, starfish, sea urchins and see horses, depending on conditions. 

After your sea trekking experience, head back to the beach to learn more about the marine life you saw. Opt to purchase the underwater photos taken of you on your tour. Bathrooms, changing rooms and shower rooms are available to all guests after the tour has concluded.

Awesome Experience
Jerome_T, Sep 2023
This experience was awesome! The 2 divers were so helpful to make sure we had a great experience and made sure we were doing ok throughout the whole time. Would do this again! Loved that they took so many pictures that we could purchase. Was well worth it!
Great time
Darryl_W, Aug 2023
The under water trek was a good experience. My only complaint is I booked 11:30-1:00 had a hard time getting through the parking lot so was about 5 minutes late. We were then rushed to sign waiver, got in about 11:40 our experience was over by 12:20. When I asked the lady didn't We pay for a hour and half tour she tells me that's incase someone gets lost or late. Which I was,but was rushed. I feel I didn't receive what I paid for. Other than that it was ok
Awesome experience

Our tour guide Matthew was very professional, friendly, helpful. He was compassionate and took his time to explain things untill we felt secure. Loved the experience, very cool. I only wish it was longer for the price.

I didn’t care for the front desk lady. She’s unorganized! The actual men who went in the water with us were GREAT!
Kristen_R, Jul 2023
The instructors were friendly and great, it was a cool experience. It was cool to go under water and walk around and see some fish.
Great professionals
Meghan_B, Jul 2023
This was AMAZING and beautiful 😍 🤩 👌 ❤️ 💖 💕 guys were professional and I felt safe when taken outside of my comfort zone.
Too much money for too little
Brian_F, Jul 2023
The guides were great. Super friendly and knowledgeable. They explained everything and were very confident. My son enjoyed the dive and loved the star fish we found. Overall, it was a good trip but $300 for about a half hour was too expensive. This was a $99 tour just based on time alone.
12/10 Experience
Rayanna_C, May 2023
Genuinely one of our best days on the trip! Our guide, Luis, was phenomenal and took steps to ensure everyone, including my friends with limited swimming ability, felt safe. This is perfect for those who have wanted an underwater experience but are not strong enough swimmers to dive or snorkel. The beach was clear and beautiful.
It's not a scary as it seems, and you don't need to know how to swim.
Christopher_W, May 2023
This was a pretty fun experience., In a great introduction into scuba diving. If you're hoping to encounter fish you definitely will, and you will end up with some pretty cool pictures. I would say it's definitely worth it to give it a try.
Very easy to do and best experience ever
JESUS_A, May 2023
