Ak'tun Kan
Take the main road through Santa Elena, turn left at the end of the road and follow signs. It is clearly marked. From the causeway in Flores, it is a 30 minute walk, or taxis are available for Q20. Inside the cave are many formations that resemble various objects, such as animals, people, and of course ordinary stalagmites and stalactites. Most of the relics are labeled in Spanish and will be identified by your guide.

A wildlife rescue center dedicated to the prevention of animal trafficking. There are possibilities to offer your services here as a volunteer (http://www.arcasguatemala...). The center operates its own boat service from Flores, with boats leaving at 8AM and 3PM. Alternatively, take a boat to the Petencito Zoo, which is located near by.
