Taxis are an inexpensive way to get around but for the most part, Tulum 'Pueblo' is so small that walking is a simple, though often dusty, option. Taxis from 'Pueblo' to the coast is ~70-90 pesos. It is advisable to either take a taxi or rent a bike when traveling between the 'Pueblo' and the beach, as the walk is rather long, dusty and unattractive.
Bikes are available for rent from Iguana Bikes in Tulum 'Pueblo.' 150-250 pesos for 24 hours. Bikes are a convenient way to get around town and to/from cenotes and the beach. Please be careful when riding a bike on the highway. Bring a headlamp/flashlight if biking at night.
There seems to be a public bus which leaves Tulum Pueblo around 9am and 12noon and goes to the beach and ruins, and returns from there at 12.15pm and 5pm. Not sure about ticket prices but they should be around 5 pesos one way.
