This eco-adventure company has won awards for developing sustainable tourism that involves the local Maya community. On the Jungle Crossing tour, you bump along dirt paths in off-road vehicles, driven by guides, until you reach the small Maya community of Rancho San Felipe. You’ll also stop at the entrance to Nohoch Nah Chich cenote, rated as one of the most beautiful underground rivers in the Riviera Maya. (It’s also the longest.) You can snorkel through the cave, rich with stalactite and stalagmite formations. The trip includes a traditional Maya lunch (kids can eat the rice and beans) and more snorkeling and swimming at Yax-muul, a natural pool. The minimum age is 6 years old.
