I tend to not like exposed, steep trails. Well, i guess i do like em, they just kinda scare me sometimes. Back a few years ago, my fear of heights was worse than it is now. The trails that have scared me the most-
1.the knife edge- not too much tough climbing, but looking straight down 2,000 feet kinda tweeks me a little. There's a spot 60 percent of the way from Baxter to Pamola where you go sideways across the face of the cliff and the path is about 3 feet wide, then drops off. I spent a couple minutes frozen there, deciding what to do.
2.the precipice in acadia- This is a lot of fun, but climbing the rungs and skirting the cliffs can be nerve racking. The first time i did it, there were plenty of slow people in front of me, so that meant a lot of time standing on ledges and looking down w/out moving. If you do the climb at a moderate speed, it's fine. If you have to wait and look and think, that's when the fear factor kicks in.
I don't know if there are many skiiers here, but i used to ski at sugarbush in VT back when i was in college, and they have the chair that goes in between the two mt areas. There is a point in between where you cross the valley and the chair is a couple hundred feet above the ground. always made me dizzy.
