We spent the morning hiking the river walk loop, filled with lots of wildlife and terrapins, and then did the Tiger Fern waterfall hike. The first hike was easy and flat, but the second hike was 4km of humid conditions as the heat of the day hit us. Swimming in the clear waters at the end was worth it. We also went to the plane wreck, which we thought was really cool and as it's only a 5 minute walk from the access road. You can also go tubing here for a small fee.
Although we didn't see the jaguars, we did see terrapins, lots of beautifully coloured birds, the 'royal rat', huge butterflies and frogs. You'll need walking boots for the hikes with any gradient and given that it often rains at night, be prepared for sloppy surfaces.
After we drove along Hummingbird highway, which is mostly paved. We camped at St Herman's cave. The workers are sound chaps and we chatted for ages about life on the road with them.
