There are two bus terminals in Tulúm. One is near the Pemex station and is open from 9:00am to 6:00pm. The ADO station is located in town and is open 24hrs. Both provide first & second class bus service. The colectivo also stops in town on Hwy 307. You can take the colectivo from Tulúm to Playa del Carmen, which is a very cheap option and fairly comfortable.
As you exit the airport there are two main taxi stands. (Easy to spot! Just look for the line-up of taxis.) Usually you do not have to search long or even call to request a taxi, as they will approach you looking for fares. There are affordable transfers to Tulum from the airport but be aware that you can get multiple prices, so bargaining is always the order of the day. Typical taxi cost is about $100 usd.
