Help us to pervent introduction of foreign fauna or flora into the islands. Check your equipment and bags before departing for any undesirable specimen such as cockroaches, mice, rats, or plant seeds. Remember, PETS ARE NOT ALLOWED ON THE ISLANDS.

Please use established trails and do not create new ones. Try as much as possible not to step on any flora and fauna. Remember the small ones that have just started to grow such as the small cacti!

Coronado Island has latrines (composting toilets) for public use: Only one latrine should be used. Please leave the second one sealed at all times. The latrine is only for human waste and biodegradable paper; please DO NOT DEPOSIT any other organic produce or inorganic waste such as diapers, feminine pads, organic produce, fish scraps, seashells of clams, plastics, or aluminum cans.

At the other islands use at all times a port-a-potty for deposition of human waste. Remember to burn completely or bring back your toilet paper.

Although campfires are prohibited, you can bring camping stoves. When using charcoal grills, make sure that charcoal burns completely. Ashes of fire should be packed out of the islands. Remember, "Pack it in, pack it out" is the best rule for dealing with trash.

Observation of sea lions, whale sharks, dolphins, mantarrays, and whales requires keeping a minimum distance of 50 meters.

Observation regulations for whales are the same for all Mexican waters.

Mexican fishing licenses are required for the boat and for everyone aboard in order to perform sportfishing, regardless if one of the members of the vessel is not fishing.

There is no limit to the practice of "catch and release". We invite you to return in good survival conditions as many fish as possible so other visitors can also enjoy sport fishing. Otherwise, follow all the fishing regulations listed on your Mexican fishing license and do not exceed your limit.

Underwater fishing is limited to five specimens (fish only) per day per person, using rubber band or spring type spears and only while free diving. This activity also requires the purchase of a Mexican fishing license before it takes place. Please be advised that while at this time underwater fishing is permitted, this regulation may change.

Fishing licenses allow the capture of finfish only. Licenses do not allow the capture of any mollusks (scallops, clams), crustaceans (lobsters, crabs), starfish, sea urchins, sea cucumbers, corals or any other marine organism alive or dead.

Fish caught under a sport fishing license may not be filleted aboard any vessel or at any of the islands. Filleting is allowed only on the coastal area of Loreto. It is prohibited to dump fish scraps in the coastal area of Loreto and other unauthorized areas. fish scraps must be disposed of at the Municipal Dump Trash Area.

If you transport your sport fishing capture via highway, ship, or plane, you must carry with you at all times your fishing license and a copy of your "Sport Fishing Report". (Described on the Marine Park Forms Page)

If you acquire products from the sea of the desert such as: fish, sea shells, corals, cacti, iron wood, mesquite or any other natural object, you must have an invoice (a FACTURA) of purchase to show its legality.

All archaeological sites are protected in Mexico by the government. Never chalk, trace, or otherwise touch rock art. Any kind of direct contact speeds the disintegration of these ancient figures. Leave arrowheads and other artifacts for others to enjoy.

Many birds and sea mammals choose Mexico as their wintering and mating ground. Respect the needs of these animals and their offspring, especially when you pass near a rookery or calving area. Avoid sudden movements, and never chase or charge any animal.
