Portal is the last segment of Mag 7, and epic. Epic in exposure (next to a 1300 foot cliff), epic in views of Moab and the valley below, and epic in technical descent down to the highway. 

The initial trail is easy and rideable.

Then, the left side of the trail disappears, and the cliff is just a few inches off the trail.

The trail is difficult enough, and then my friend Brian endoed.

Bryan was fine – he got up and dusted himself off. At that point, we all got a little more conservative and off the bikes.  There are two BLM signs on the trail that warn you to “Dismount now, bikers have died here” and we heeded the warnings. 

After the exposure, the drop down to the highway is hugely technical and lots of hike-a-bike unless you are a rock hopping expert.

I was able to catch Bryan’s endo on the vid below.
