Fodor's Expert Review Cerros
Like the Tulum site in Mexico, Cerros (also referred to as Cerro Maya, or Maya Hill in Spanish) is unusual in that it's directly on the water. Unlike Tulum, however, there is little development around it, and at times you can have the place all to yourself. With a beautiful setting on a peninsula jutting into Corozal Bay, near the mouth of the New River, the late pre-Classic center dates to 2000 BC and includes a ball court, several tombs, and a large temple. Altogether, there are some 170 structures, many just mounds of stone and earth, on 52 acres. There's also a small visitor center. Bring plenty of bug spray—mosquitoes can be fierce here.
The easiest way to get to Cerros is to charter a boat in Corozal Town, for a 15-minute ride across the bay.
