Furthermore, the Mayan ruins are within driving distance, which you can go to yourself with a cheap rental car or with one of the tours that is offered on every corner of the street.

Also eco-adventure sports (kayaking, mountain biking, trekking, bird watching and fishing) are popular.
There are multiple golf courses in the area. Nightlife is good with plenty of restaurants, bars and clubs.
