Visiting Mexico’s protected areas without getting it wrong

Who protects what

INAH — the Instituto Nacional de Antropología e Historia — administers archaeological zones and the objects in them. Its rules are about the structures: where you may walk, what you may climb (almost nothing, these days), what you may carry in, and increasingly how you may photograph. The thing being protected is masonry that does not repair itself.

CONANP administers natural protected areas — reserves, national parks, marine parks — and its rules are about living systems. Distance from wildlife, seasons, authorised operators, capacity limits, where boats may anchor, what sunscreen may enter the water. The thing being protected can move, breed and die.

Where they overlap, both sets apply. Tulum’s ruins sit beside a coastal area with its own protections; the reef parks off Cozumel and Puerto Morelos have marine rules on top of everything a normal beach has.

The rules visitors break most often

What to check before going

Find the official name of the place and the body responsible for it — the tour product’s name is often not the site’s name, and that matters when you go looking for rules. Then check the current notice: fires, storms, sea state, a closed trail, a capacity cap, a section shut for conservation. A visitor center being open does not mean everything behind it is.

Where an authorised guide or a community operator is required, that requirement is not advisory. In several reserves the visit is only legal through a local cooperative, and an operator offering to skip that is offering you their fine as well as their trip.

Last thing, and the one people forget: know how you get out. The last boat, the gate closing time, the point where the phone stops working, and who to call. In a protected area there is frequently no coverage and no infrastructure by design.

Behaving well is mostly obvious, except for one part

Stay on the trail, take your trash with you including the organic parts, leave what you find, keep your distance. All of that is intuitive. The part that is not intuitive is photographing people: guides, artisans, residents, and above all ceremonies. Ask first, accept a no, and do not photograph a ritual because it is happening in a public place. It is not a performance.

Use the Cozumel guide, the Tulum guide and the Chichén Itzá guide for the geography, then find the specific authority for the specific site you are visiting.

Traveler questions

Is every archaeological site also a protected natural area?

No. The protections can overlap on the same ground, but INAH and CONANP have different mandates and different rules.

Can I use my own sunscreen?

Not in reef parks and most cenotes. They require approved products or none at all, and they check. A long-sleeved rash vest avoids the problem.

Can I fly a drone?

Usually not, and never at an INAH site without a permit arranged in advance. Assume no unless you have written authorisation.

Can I take a shell home?

No. Removing natural or cultural material from a protected area is prohibited, and some of it is a customs problem as well.

Do I have to hire a guide?

At some reserves yes, and specifically a community or authorised one. Check the site rule rather than the tour seller.
