To get to the cache park at the parking lot near Youngs River Falls and then follow the trail up toward the top of the Falls. You need to be carefull, especially with young children as the trails can be muddy and you are near cliff tops. The hike is not more than 1/4 mile, first up and then down, but it can be a scramble. So be aware. The cache is a small lock'n'lock that will hold small items. There is a dollar coin for FTF.

I had to move the cache as the original hiding spot is no longer viable. You have to go past a no tresspassing sign to get to it. So I moved it closer to the parking area. It should be a lot easier to get to and is well away from any cliffs. I have updated the hint as well.
