Take the only highway south towards Tulum - Chetumal, and drive until you arrive at Tulum (the town is along the highway). It will take you approximately 2 hours from Cancun Airport.
At one point at the traffic lights you will have at your right hand side a green sign saying Coba, and a San Franciosco store. Do NOT turn right, but take a left towards Tulum Hotel zone and Boca Paila (Punta Allen).
Drive along the road, past the fire station, until you meet another road.
Take a right, and drive along the road until you see, on your right hand side, a series of small hotels.
