The Portal Trail
Exposure on Portal.
This is the one aspect of the trail that I had heard most about.
Though certainly intimidating if you are not used to narrow single-track,
this is the easiest part of the ride.
But by all means,
do not under-estimate the consequences of a screw up.
It is a 500+ foot, more or less straight-down drop on the left.
Typical step drop on Portal.
Here Jeff descends a drop on the second switchback.
Later on in the trail (after the exposure)
these become more frequent and more intense.
