Land Owner
This is a steep trail with switchbacks and one of our longest northshore bridges with many unique feature options.
It starts off really steep, with some steps that drop you down into a tight turn. The drops are maybe 2 feet but successive, making this very difficult. Then a long and steep winding roller coaster. The roller coaster has a sign warning that at the top you can't really stop, so this is your last chance to dismount. But the roller coaster is easier than the steps before it, and the end is a nice roll.
