We did the jungle river tour in Limon and it was great. We would do it again in a heartbeat. The guides were very knowledgeable and we saw lots of wildlife. Even the sounds were awesome as we traveled along the river.
When you get off of the ship, seek out the Red Canopied tent. There will be a pre-printed sign with all of their tours & prices listed. (No Haggling) We took the number 1 best rated tour: Tortugero canal and Banana Plantation tour. It was about 3 1/2 hrs. with additional stops and tour of the Dole Banana Plantation, Playa Bonita, stops to see their flora & fauna and the 3 toed sloth and monkies. Our driver even brought us to a local supermarket at my request so I could purchase coffee and vanila. He also helped with the currency conversion. This was $45 per couple.
