Tulum is on the Yucatán Peninsula, in Mexico. It is one of the earliest resorts in Mexico, offering a place of worship and solitude for the Mayan kings, clergy and gods in early times. The tropical beach backdrop is the main attraction of this picturesque, much-visited small ruin on the shore of the Caribbean Sea. Shortly after your arrival, you will understand why early Mayans picked this beautiful place to relax.

Be prepared for lots of people and tour groups at the archaeological site. To avoid the crowds, it is best to stay overnight and visit the ruins early in the morning before the buses arrive, or later in the afternoon. Morning is recommended since you can catch spectacular vistas when the sun is rising over the Caribbean.

There are really three different areas referred to as Tulum. There are only minutes away from each other, not close enough though to walk to and from.Tulum Pueblo sits split by highway 307 running south-north. "El Pueblo", as referred to by locals, is home to most workers of the tourist industry and where many of the stores, supermarkets, two bus stations, budget inns, hostels and small hotels are found. Tulum Playa nests along the coastline that leads into the Sian Ka'an Biosphere [Ecological Reserve], the Caribbean white sandy beaches to the east, an impressive mangrove & wetland reserve to the south. Tulum Ruinas is the archaeological site where the Maya ruins of Tulum stand.
