Tour Summary
The tour begins at the CESiaK ecological center where we have an introductory discussion and view the coastal flora and fauna. The tour continues by boat traversing the two northernmost, brackish lagoons. In this area, we pass a small Mayan ruin and view up-close the mangrove islands which are nesting areas for many of the birds found within Sian Ka’an.
The tour continues south along the peninsula to the lagoon of Boca Paila where we turn inland and enter the narrow 11 km natural canal which traverses the expansive mangrove swamp and savanna grassland which comprise much of the center of Sian Ka’an. Along the journey we are surrounded by birds, tall mangrove trees, orchids, bromeliads, termite mounds, fish and much more.
The canal ends at a Post Classic Mayan Temple hidden in the mangrove swamp with beautiful frescos and a well-preserved inner sanctum. After visiting the temple we continue by boat to the freshwater Lagoon of Chunyaxche where we see some examples of the thousands of small sink holes (cenotes) from which the lagoon is filled.
After a snack and refreshments we enter the canal once again to commence a half-hour relaxing float wearing lifejackets and being carried by the water’s current. After getting back in the boat we travel to the ocean edge passing wide sandy flats where rays, predatory birds, and many fish are found. Continuing under an antique wooden bridge we follow a waterway which allows us passage to the ocean to view the seemingly endless expanse of tree-lined, sandy beach. We end the tour following the peninsula back to CESiaK for a sit-down lunch (included in the price) in the center’s restaurant and for some relaxation on the beach.
