Elephants generally just crash through and make their own paths. Heaps of buffalo and elephant dung were barely discernible in the muddy path, but the huge elephant footprints were quite clear. An armed ranger walks with you, just in case you do come across these animals.
The pleasant looking bamboo forest gradually gives way to steeper slopes, muddier conditions and incredibly dense vegetation, seemingly made up of giant stinging nettles. The guides and trackers hack through with machetes, and we simply tried to keep up. The nettles burned right through my jeans and jacket, luckily the sensation only lasted about 5 minutes. Here's a short video of us getting closer to the gorillas.
