On Guam, my friends and I would often hike to remote beaches and waterfalls. Sigua Falls took about 3hrs to get to, and you had to trek through hills, sword grass, and repel down a steep, muddy slope holding onto a rope for dear life. It was glorious!
I remember one adventure where I was in a particularly bad mood, trekking through the mud and grass during high noon. I griped part of the way, especially incensed with one of my friends, traipsing through the mud with twigs in his hair. Once we found the falls, though, I immersed myself in the cold, gushing water and my mood completely melted. Sigua claimed me again that day.
