Scuba diving is one of the favorite activities par excellence of people who visit Cancun, due to the beauty of its interior waters and the crystalline view that these waters offer anyone who dares to dive into the depths of the Mexican Caribbean.




But… Where can I dive in Cancun?

One of the most popular dive sites in Cancun, without a doubt, is the Underwater Museum of Art (MUSA), which has hundreds of life-size sculptures located between two locations, Cancun Punta Nizuc and Isla Mujeres, West Coast.

Just imagine! Diving is like visiting a new museum, park or attraction, but this time underwater, where you can find marine species in their habitat and coexist with nature that we don't see every day. Don't forget that this activity is extreme, so take your precautions and don't forget to respect the sea and its inhabitants.


What should I know before diving in Cancun?

What should I know before diving in Cancun?

  • Relax, don't despair. The waters of the Caribbean are really calm, and most of the diving tours include certified divers to help, guide, or advise you through this incredible experience.
  • Be sure to adjust your equipment for the best support during your activity. Wetsuits and equipment available come in body-specific sizes, from small to large.
  • Stay close to your group at all times. Safety first, remember to stay close to your dive group and the expert divers to avoid accidents or mishaps during your underwater activities.
  • Follow the instructions. The tour staff and divers are experts at what they do, so be sure to follow their instructions to make the most of your diving time.
  • Respect marine life. Just because you can swim with marine species does not mean you can touch them, much less disturb their natural habitat. Dive with caution and respect.

What do I need to know about the whale shark swim experience?

By embarking on this experience, you must commit to the following:

  1. Keep at least 5 or 6 meters away from the whale shark (the same distance and even more are required for boats).

  3. Avoid making sounds to attract the shark's attention.
  4. Always remember that you are the one visiting their habitat. Respect the sharks and the species that live in the sea.

Here are some recommendations for your starfish-watching activity in Cancun, Playa del Carmen, Tulum, or Cozumel.

  • Don't touch starfish! ➡️️ Learn more in this article about why you shouldn't touch a starfish, which we have detailed to provide you with as much information as possible about this activity and fun facts about starfish.
