Punch Bowl
You can reach the cool water here by shimmying down a muddy rock bluff. Or, a quicker way would be to jump. Hanging over a beautiful waterfall, the bluff is about 80 feet above surface level. It takes maybe two or three seconds to fall (but feels a lot longer). Last summer, a friend jumped from the overhang and bruised his thigh. He told me that the next woman who jumped landed on her back. For several moments, she couldn't move her legs and had to be rescued. (She had put a hairline fracture in her spine.) When EMTs arrived, they said they're called to Punch Bowl a dozen times every summer.
A week earlier, the EMTs continued, a guy had jump spread-eagle from the rocks and landed on his nuts. The force pushed his testes into his body cavity. He didn't have health insurance so he refused their help and had friends carry him the two miles back to the parking lot.
Punch Bowl is reachable from the popular Eagle Creek hiking trail. From I-84, take Exit 41. Follow the meandering road to the parking lot. There are two paths. Take the one that goes directly away from the parking lot, toward the south.
