The mother of all Mayan ruins? If not, whatever is better must be truly spectacular. This was a great time of year to go, as the weather was perfect and the crowds nonexistent. As we walked through the jungle, we saw and heard numerous birds and monkeys, including the infamous howler monkeys. The oddest moment came when we witnessed what has to be the strangest turkey I ever saw, sitting in a tree next to one of the temples (see photo in gallery). Make sure you climb the temples, too - the views are great from up top, and the climb itself up the rickety ladders is an adrenaline rush.
