If you want to cool off from the heat, this is a great place to go! Just an hour south east from San Juan, El Yunque is an fun adventure! Stop by the kiosko's in Luquillo along the way!
We went here on one of our trips while we were staying in Old San Juan! The breakfast was delicious-- coffee was even better!
The zip lining here was the BEST! Jimmy Fallon even went to this specific one as well, so you know it's good!
