We just finished a 4-day pre-arranged tour of the Cayo district in Belize. Our guide, David was awesome. He was friendly, outgoing, an expert on everything we did. He let us set the schedule each day and took care of everything. Very professional. He got really into birding with us and knew so much. He knew where to look for specific birds almost on demand! I would recommend this to anyone and suggest you get David as your guide.
