End of the excursion

It's a pity, but the day is over. In Mayan, Sian Ka'an means "Heaven's Gate" and after this day you will have no doubt about the reason of that name. This biosphere reserve of Sian Ka'an is a natural wonder composed of rainforest, cenotes and islands. It is a beautiful place that will impact you and give you one of the best moments of your trip in Mexico.

Questions & Answers

  • Can I bring my camera or mobile phone on the boat?

    Yes, you can take your electronics with you. The boat does not splash, but in case of big waves, it has a space prepared under the seats to store your belongings. When we do the snorkeling activity, you must leave them in the boat next to the captain.
  • How big are the groups?

    The group starts with 12 people but later we will divide into 2. This way, you will actually do the activity in a group of 6 people. The groups are reduced to keep the personalization of the tour and for a greater comfort of the travelers. In addition, we are interested in respecting the fauna and going in large groups can be detrimental to the biosphere reserve.
  • Why should I take this tour?

    Mainly because Sian Ka'an is a piece of heaven on earth. It's a paradise made up of virgin beaches, islands and animals. On the other hand, this tour spends more time on the boat ride than on the land, unlike other tours. This allows you to get closer to the species that inhabit the place and go deeper into nature. We want to turn your experience into an incomparable adventure and that is why this day is worth every penny.
