Golden Spike trail is part of the trifecta of trails in Moab which consists of Gold Bar Rim, Golden Spike, and most of Poison Spider.
On our recent mantrip to Moab, Andy and I actually ran all three of these trails (alone) and (almost)without incident. There were many cases where we took the easier option as we had no other rigs with us.
The trail officially “begins” on the Poison Spider side, but we ran it in reverse from Gold Bar Rim. The area is very well signed. I am actually glad we traversed it in this order, as some of the descents we made off ledges seemed pretty difficult if we were climbing them. The “point of no return factor, however was a bit daunting.
