Make a day trip to Coba. Tour and climb the Mayan built pyramids at the Cobá Zona Arqueológica. You can also visit the Coqui Coqui hotel and spa (my favorite candles, perfumes, etc). Don’t forget to swim Coba’s cenotes (underground lakes !!). Paolo and I hired a taxi to take us to Cobá from Tulum and he stayed with us all day to drive us to the different sites and back to Tulum. Very reasonably priced!
