Although they do not have you feed the howler monk...

Although they do not have you feed the howler monkeys anymore it was so cool to literally be standing right under the trees they were climbing around in. Be sure to wear sneakers lots of walking in jungle area and drink lots of water when the sun is full force it gets pretty toasty. The guide was super friendly and very informative about the jungle life. There are bathrooms where you check in, go before you walk so you can just relax and enjoy the howler monkeys for as long as you'd like
