Palenque is in Chiapas, Mexico famous for the ruins of a Mayan city dating from about 600 AD to 800 AD. Set amidst thick trees, Palenque still evokes some of the wonder that the early Spanish visitors must have felt when they first came across the ruins.
Palenque Mexico is actually a medium-sized archaeological site, much smaller than the huge sites like Tikal or else Copán, but it contains a few of the finest sculpture, architecture, roof comb as well as bas-relief carvings of the Mayan era.
A new airport just opened in Palenque with direct flights from Mexico City with Interjet (~$150 USD each way) and Tuxtla Gutiérrez with Ka'an Air (~$115 USD each way). As of May 2014 there was no shuttle bus from the airport. The only option are fixed priced taxis - to city centre only 3km away (M$200) and to the ruins area about 7km away (M$250). The closest public bus from the airport is over 2km away.
The next closest airport is in Villahermosa is about 2.5 hours away by road. Tuxtla Gutiérrez, the airport for San Cristobal de las Casas is five to six hours away by bus. Both airports are well serviced with flights from Mexico City and other points in Mexico.
The easiest way to get to Palenque is by bus. From airport you can take prepaid taxi to bus station in town, which is 280 Pesos(on august 2014)and it takes 30 minutes. There are two bus stations in town and both are just 2 minutes walk distance between them. There are many buses daily from San Cristobal de las Casas (five hours), Tuxtla Gutierrez (six hours), Villahermosa (2.5 hours), Merida (8 hours), Campeche (5 hours), Cancun (13 hours). Daily (one or two buses) also ply from Mexico City (16 hours), Oaxaca (15 hours), Playa del Carmen (12 hours), and Tulum (12 hours).
Also if you would like to blend in with people and culture collectivos (Passenger Van) are best way. Take collectivo from Tuxtla Gutierrez bus station to San Cristobal de las Casas (2 hours/50 Pesos), then to Ocosingo (2.30 hours/60 Pesos)and finally from there to Palenque (2.00 hours/ 60 Pesos). Also you can stay overnight any of this towns to continue journey for next day. Taxis are really cheap around 20 Pesos to most of the hostels/Hotels. Collectivos starts service early morning mostly by 4.
It is also possible to get to Palenque from Flores in Guatemala by bus (6h, leaving Flores daily at 5am, USD 35.00).
The ruins are about 6 km from the town of Palenque and collectivos run between the town and ruins every 10 to 15 minutes during the day. Cost is 20 pesos flat rate around the town. (September 2016) There are a number of visitors (both International and Mexican) who drive around, so hitchhiking is another option.
Spend a whole day exploring the site which spreads over 15 sq km. Only the central acropolis has been excavated. The Templo de Las Inscripciones, a burial monument, is the tallest building. El Palacio, the rulers' residence, was built in stages from 400 AD to 900 AD and underwent restoration in 1955. There's a 31 peso fee to enter the national park, and then another 65 peso for the ruin site (September 2016).
There are two entrances to the ruins - The first one starts from the jungle part of the ruins and is often overlooked by people who head straight to the main entrance 1.5 km away. If you arrive there in the early morning (The ruin opens at 8am), you would likely be the only one to enjoy the serenity of the ruins before other visitors start coming in. Palenque gets hot and humid around noon, so start the trip early!
There is an entrance to the trail between ruin entrances - don't miss it for more 'jungle experience' featuring howler monkeys, waterfalls and hidden ruins.
A short hike to the nearby Mishol-Ha waterfall offers a variation on the ruin touring. This is a high waterfall into a natural pool with a path leading behind the falls to a cave. Bring a swimsuit and only swim during low flows.
Many tour operators will offer guided visits of the ruins, providing added background and knowledge regarding Palenque's history.
You can get some Maya-style artwork from outdoor vendors who set up unobtrusively at the ruins.
Sleeping accomodation can be found either in the city of Palenque, or just outside the limits on the road to the national park. That's the main question you have to ask yourself - whether to stay in town or in the jungle. The town saves you on food, the jungle on accommodation. The jungle is well worth it.
Other ruins in the general area are Yaxchilán and Bonampak. These can be arranged by day trip (650 pesos, december 2013) or overnighter (1,250 pesos, december 2013) with any agency in town. Misol Ha and Agua Azul are famous waterfalls in the area. The towns many tour agencies organises 7 hour combination trips to both falls for 130-150 pesos, excluding entrance fees (30 and 38 pesos respectively). (December 2013) The falls are just an hour or so outside of the city, but the tours are arranged so that there is time to swim and eat (at Agua Azul).
Entrance for Aqua Azul 40 pesos (2015, March)
Update March 2015: From Palenque to Merida directly is only ADO, but be careful. We met 7 people from one bus got rubbed all their things. (They had their bags between their legs!!!!) It's around 570 pesos per person! BUT there is a cheaper option. Take a colectivo for 25 pesos to "cruzera del playa" wait there. It's only one bus (TRT bus) per day that goes to Merida (it arrives at the bus stop around 12.30p.m.) It cost 371 pesos (April 2015) and the journey takes 10 hours. But because it's local transport in this case it's propably more safe! Have a good stay/travel!
