“We had a fantastic time on this boat tour from Kotor. The journey was absolutely beautiful and sitting at the stern made it even more enjoyable. Our guide was super friendly, funny, and shared just the right amount of history and local stories without overwhelming us - it was a great balance. The atmosphere on the boat was relaxed and fun, and the views were stunning throughout. This is definitely a must-do experience if you're in Kotor. Highly recommended!”

★★★★★★★★★★4.5 · 3,406 reviews · 4 hours (approx.) · from $48

Ride an ATV through the jungle, swim in a cenote, cross three zip lines, sample tequila, and eat two tacos on a roughly four-hour outing from Cancun or Playa del Carmen. Guides such as Alan, Raul, Julio, Nacho, and Ernesto are praised for keeping groups safe and entertained.

“You get what you paid for. The quality is very poor and minimal. From the second you step foot in the parks they immediately try to sell you the “premium” package, which is not worth it. Then they walk you to the gift shop to try to sell even more items to you. And they don’t allow phones or video cameras which forces you to buy their images if you want memorabilia. They scammed us by telling us one price in USD, and charging our card way more. They switched out the receipts which gave me no evidence of the promised price when trying to dispute it with my bank.”

★★★★★★★★★★5.0 · 1,888 reviews · 6 hours 30 minutes (approx.) · from $169

Spend a full day visiting Tulum, swimming through the El Sueño cenote, snorkeling at Yal Ku Lagoon, and eating lunch by the beach. Guides such as Santiago, Lalo, Gato, and Jessie are praised for safety and humor. Expect long drives, rough roads, and a late lunch.

“The time at Tulum was underwhelming. Our guide did a good job, but it was hard to get perspective. The visit to El Sueño cenote was amazing. Swimming through a cave is a cool experience. You’re not allowed to take your own photos. The snorkeling in the lagoon was great. There were many beautiful fish. The tour operator provided nice towels. A member of our group didn’t feel well, so we asked the guide to return us to our resort rather than take us to the beach club for lunch. The cenote was the most memorable experience of the day.”

“Fun experience! I was a little worried since Ive never rode a horse before. We were well taken care of by the crew there. Both Lily and Paula were great! It was a great combination of activities. If you’re scared of water though, the cenote is pretty deep.”

“We went with my mom and I have three boys, age 4, 7 and 11. One note, depending on how far your hotel is your trip to the start point, maybe up to 2 hours long. We were the furthest of our trip and it was 1.5 hours. The bus was very nice. And all three of my kids didn't really have a problem with the trip getting there. I was glad that the tour guides were very diligent. Because I thought we were getting picked up at our hotel at 9:00 a.m. but we actually got picked up at 7:00. They made sure I knew the right time the…”

Ride a fast Zodiac RIB from Kailua-Kona to Kealakekua Bay with guides such as David, Chip, Sage, or Danielle. Snorkel near the Captain Cook Monument, then cruise past lava tubes and sea caves. Pineapple, water, and basic snorkel gear are included. Dolphins and whales are possible, never promised.

“Danielle and David took us to where Finding Nemo and Moana got their inspiration and we can see why. The water was so calm and pristine, our best camera couldn't capture the beauty of it. You just have to be there truly. They were rather knowledgeable and told lots of stories and history tidbits about the region. My parents came to visit from China and don't swim very well. They were beyond patient and kind making us feel comfortable. This was the highlight of our 10 day Hawaiian trip honestly. PS: If David's mother is reading this, David is a terrific captain and really great at his job!!! 🌴”
