Where Drive up hwy 70 until just before the Rock Creek Power Plant. Drive up the gravel road as far as you dare and park here. Take the trail along the creek to the water slide and swimming hole.
When Best in mid to late summer when it's hot because the water is pretty cold.
What This is some great fun and adventure. The scenery is beautiful. There is a great swimming hole with rocks to jump off and a waterfall. There is also a natural rock waterslide.
What Every year, on the first of January, the truly brave among us emerge to test mind and body by swimming from one end of One Mile to the other. Last year was my first time and I thought it was awesome. The air was about 50 degrees and it started to rain a little while we waited. A huge crowd of swimmers started to gather at around 1:00 PM, many of whom had just woken up after their New Year's even celebrations. On the other side of the river someone set up a digital count-down to 1:30 PM, when we would all dive in. Many family and friends waited on the other side with towels and warm food. When the time came to go my heart was racing. Would I be paralyzed from the cold? Would I get kicked in the head by some panicked swimmer? I dove in and swam to the other side like a race seal. I was made to do this. You can see me in this video below. At 5 seconds in I am the tall guy with the beard on the left hand side of the screen.
