My girlfriend and I took the Tortuguero Wildlife Tour from Puerto Limon to Parque Nacional Tortuguero last month and it was a great experience. William Guerrero answered my international call to help plan my arrival, and sent a shuttle service to the hotel we stayed in when we arrived to Puerto Limon. All of the hotels in the área knew William, and also helped us call him when we arrived. The tour was full of wildlife, with a friendly tour-leader giving a decent explanation of the animals that we encountered. The boat was clean and comfortable. I would definitely recomend taking the Tortuguero Wildlife Tour when making the trip to the National Park.
