I would still do both. Both are different experiences and very worth it. We saw toucans out our window every day at Bolita (was fantastic!) and there are a lot of frogs in the area. There are also sloths but we never got to see them unfortunately. The atmosphere at Bolita was so relaxed and the scenery is stunning. I felt refreshed and rejuvenated when we left there. We also did a two day hike into the national park - there is no point in doing the one day hike. You only get so far befor you have to turn around and there is little reward. What you see largely depends on your guide, however. We had a wonderful guide, Roger, who was organised through the very kind owners of the hotel / hostel Oro Verde (I would highly recommend to stay there while in Puerto Jimenez. It's cheap, clean and the owners really go out of their way for you). Roger was incredible. He knows the forest well and knows how to track animals. We saw everything from tapirs to ant eaters to even a puma! It was a long two days but I am so glad we did it. Other people hiking on the same day as us zoomed past with their guide who didn't seem to care much about what was going on and they hardly saw anything. Be careful who you book with!

Just contact the Bolita hostel. There is a contact form on their website. I can't put their email here. It is bolitahostel. Gmail. You can also google : workaway. It is a volunteer site. Click on host list. Look for Central America and Bolita.
