I spent today with a fellow cacher, and we made our attempt at a geocache that has a difficulty and terrain rating of five (out of a possible five). It is a seven part multi-cache, with each leg of the cache providing the coordinates to the next leg. The terrain was intense, but I'm not sure what it's like through the entire seven stages, since we were foiled after only two.
We had dense cloud cover today, and the second stage was near some high-tension power lines. I'm not sure if those two conditions, combined with the dense jungle canopy, led us astray, but we were unable to find the cache. We got a little beat up, and very dirty in the process.
There was a dam in the area, and I took a picture from on top of it. After that, it was off into the jungle.
After failing to find that cache, we hit some others that involved a little bit of a hike. There were some banana trees, with some small bananas growing.
This trail was probably the easiest part of the day.
