My family will be in Novo Airao for two days in July (Two adults and two small children). We would like to go on a few excursions to see the National Parks. I'm having trouble finding information for Novo Airao. Apparently you can hire people with boats to take you to do anything you want. Do we need reservations, or if we just show up? If we wanted to arrange something ahead of time are there any operators in Novo Airao people would recommend?
