The ruins of Tulum stand on a limestone cliff roughly 12 metres above the Caribbean Sea, on the coast of Quintana Roo in the heart of the Riviera Maya. It was one of the last great Maya cities to flourish, built mainly during the Late Postclassic period and reaching its peak between the 13th and 15th centuries — consistent with the circa-1200 date recorded for this site. Unlike most major Maya centres, which were built inland, Tulum also served as a fortified seaport, ringed by a defensive wall that still outlines most of the archaeological zone today.
The wall enclosing the urban core runs for about 400 metres along the sea and 170 metres along each of the two sides perpendicular to the coast, standing 3 to 5 metres high and roughly 8 metres thick. Five narrow gateways — two on the north side, two on the south, and one on the west — gave access to the city, watched over by small towers at the southwest and northwest corners. Inside the walls, a small cenote supplied fresh water and a sandy cove allowed canoes to land, which helps explain why Tulum became an important trading post: it functioned as the port for Cobá and received obsidian carried nearly 700 km from Ixtepeque in Guatemala, alongside feathers, copper, jade, salt and textiles exchanged with central Mexico and Central America.
The site's most photographed building is El Castillo, a roughly 7.5-metre pyramid built in stages on top of an earlier colonnaded structure, its upper-room lintels carved with serpent motifs. Nearby, the Temple of the Frescoes combines a lower and an upper gallery and is thought to have doubled as a solar observatory; above its western entrance sits a stucco "diving god" figure, and its interior still preserves Mixteca-Puebla-style murals — visitors are no longer allowed inside, precisely to protect the paintings. The single-room Temple of the Descending God has a west-facing doorway and a narrow staircase built over an even older temple.
The first Europeans to sight Tulum are thought to have been members of Juan de Grijalva's 1518 expedition, via an account by Juan Díaz. The city stayed inhabited for roughly another 70 years after that first contact before being abandoned by the end of the 16th century. It then lay largely forgotten until explorer John Lloyd Stephens and artist Frederick Catherwood documented it in 1843. Serious excavation and restoration only began from 1913 onward, led by Sylvanus Morley and George Howe, continued by the Carnegie Institution between 1916 and 1922, by Samuel Lothrop in 1924, by Miguel Ángel Fernández in the late 1930s and early 1940s, by William Sanders in 1956 and by Arthur Miller in the 1970s — a century of phased archaeological work that shaped the site as it's seen today.
The site opens at around 8:00 a.m.; published closing times vary by source, ranging from as early as 3:00 p.m. to as late as 5:00 p.m., so it's worth confirming locally on the day. Two tickets are required: entry to the archaeological zone itself (around 100 Mexican pesos, usually cash only) and the CONAP national-park wristband (around 415 pesos, payable by card or cash); bringing a video camera adds a further fee of about 35 pesos. Arriving before 10:00 a.m. — when the larger tour groups from Cancún and Playa del Carmen tend to show up — is the best window for smaller crowds and cooler temperatures. Tulum sits roughly 130 km south of Cancún and about 68 km south of Playa del Carmen; you can get there by colectivo (around 30 pesos from Tulum town), taxi (100–300 pesos) or by car via the access road off Highway 307, with paid parking near the entrance (about 50 pesos) followed by a roughly ten-minute walk to the site.
The archaeological site sits only about 350 metres from Playa Paraíso, making it easy to pair a visit to the ruins with a swim in the turquoise water of the Riviera Maya on the same trip. According to figures reported for 2017, Tulum was already the third most-visited archaeological site in Mexico, behind only Teotihuacán and Chichén Itzá — a somewhat dated figure, but one that gives a sense of how much demand the site already drew.

A small cove within the walled site was historically used to land canoes. For a reliable swim, Playa Paraíso — just about 350 metres from the archaeological zone — is the safer bet.
No. Unlike Chichén Itzá, the Tulum ruins don't carry UNESCO World Heritage status — the site is designated a Mexican National Park.
About two to three hours is enough to see the site at a comfortable pace, not counting travel time.
