How do I visit the reef in Puerto Morelos?

When hiring a boat or a local guide to go to the reef, you need to make sure you're working with an authorized vessel and a certified tour guide. This is because the Coral reef barrier is a protected area under federal law, and entrance and activities into it are controlled and need to follow certain conditions, including paying the fee and going with a certified tour guide. The tour guide is responsible for explaining the rules and making sure you follow them.
