Chacchobén Ruins are about 73 km (45 mi.) w. of Majahual. The signed turn-off is on Mex. 307 just s. of the Mex. 307/Majahual access road junction; from this point, the site is 9 km (5.5 mi.) w. of the highway. Chacchobén is an old site, believed to have been settled around 200 B.C., although most of the nicely restored structures here date to around A.D. 200-700.
The most impressive pyramid (Templo 1) is in Group A, just beyond the Gran Plaza. The park-like setting, shaded by palms and banyan trees, is usually peaceful; however, the site does see large tour groups when cruise ships are in port at Majahual. If you're on a cruise ship that stops at Majahual, these are the Mayan ruins you'll most likely be visiting on a shore excursion.
