It's amazing at Mike's place! We wanted to be in the jungle as much as possible while in Belize, and Mikes Place provided exactly that. We had planned on doing the ATM tours, but after arriving at Mikes we decided to do the extended tour he only offers to his guests staying on the property. We're so glad we did! It was just as cool, if not more so, than the ATM one. But that's only from what we've heard. We also had access to the natural pool that forms outside the cave, where we could go swimming whenever we wanted. It was awesome. There's a 20 ft cliff to jump off into it! The guides are all super friendly and informative as well. Definitely eat at the restaurant too, the food is absolutely amazing!
We totally recommend Mikes Place. He was very responsive to our questions, and very accommodating to any requests.
