Yes, but not much. Do not depend on ATMs in La Macarena and most places will not take credit cards. You should take some spending money with you. The village has a lively ambience and you may well want to have drinks in the evening. Bear in mind that your trip with The Colombian Way is a complete package and you will not have to pay for meals whilst on your tour. If you are making your own way to Villavicencio from Bogotá then you will also need approximately 30,000 COP per person for the bus each way and 10,000 COP each way for taxis between the bus terminal and airport.
