Casa Blanca Lodge, Mexico's finest bonefish and tarpon tours.

The abundance of marine and wildlife in the Sian Ka'an is hard to imagine until you have seen it for yourself. You can find over 325 species of birds, from hummingbirds to the rare six-foot tall Jabiru, the world's largest flighted bird. In the back of the bay you might glimpse a manatee. Four different marine turtles nest on the beaches — Loggerhead, Green Sea Turtle, Hawksbill and Leatherback. The species of fish in Ascension Bay and on the barrier reef are too numerous to name. One visiting writer was so amazed by an afternoon snorkeling, that he compared it to wading in an aquarium.

These activities are available at either lodge: sea kayaking, wind surfing, snorkeling, birdwatching, hiking, beachcombing, turtle and dolphin watching, bicycling and visiting Mayan Ruins.

The reserve contains 22 registered archaeological sites. Two of these are just down the beach from Casa Blanca. Both have small, "late" Mayan temples that were constructed around 600 to 900 A.D. One site is named Chac Mool. It overlooks the beach on the Caribbean side of the island and consists of two temples and several other buildings that appear ceremonial in nature. The other temple, Tupak, was built on the water and can only be reached by wading through the mangroves and lagoons which surround it. Its foundation is made of ancient conch shells and coral rock that elevate it just above the water. Other residential sites are scattered throughout the jungle.

Enjoy Mexican historical sites while you break from bonefishing.
