Rosalia is a great tour guide. We were a group of 22 people that included kids of all ages. Rosalia was so well informed and kept everyone's attention. The tour to Coba was incredible. We also went to Punta Laguna and observed a Mayan ceremony and saw Howler monkey, ziplined across a lake (terrifying for me but also super fun), and also canoed. The highlight of our trip was having lunch with a family in a community. The food was amazing and we helped make the tortillas. I highly recommend Rosalia!
