Spiro was once used as a way to climb up to the Mid Mountain Trail
, or other much longer trails and rides in the area. However, it's become more of a trail for riding down than up, and it's no longer a great way to get up.
Now, the best way up is to take Armstrong
, which is one-way.
The trail is very smooth, and consistently up/down, depending on which way you're traveling. On the way down, it's fast, with no technical features to worry about.
