This rapid is too tough for rafting, but the kayaker is still capable to do it.

Another rapid that we could not do.

This is a very difficult one. Our raft got stuck in the middle of the river. We tried many different way but could not move. Eventually we have to leave it and pull it using a rope. It took 3 guys to pull it through!
Class 4 river, very challenging. Very exiting experience!
The starting point of our rafting trip
descending the raft from the bridge.
Rapids in the river
Our raft capsized in a rapid, all 4 people were thrown into the river. This is after we finally reversed the raft. All bags were displaced. Luckily we didn't lose any bag.
This spider is bigger than a palm.

Challenging and yet lots of fun. Every time I look at these pics, I can smell the jungle, its trees, water, mountains and those beautiful plants which I don’t even know the names. For anyone who wants to indulge with nature, this is your best bet!
That thing on the last two pictures, is that a worm/or local food? I suppose you probably ate it anyway after exhausted yourself rafting. 
I guess it’s well worth it as it tastes like shrimp as you mentioned. There are already 2 billion people worldwide who routinely eat insects, even U.N. encourage eating insects. Only in Western countries does the practice retain a tough sell.
