Gold Bar Rim Professional Review and Guide
"This is the deep end of the pool, the brink of mountain biking, the pinnacle of the sport, a ride only fit for the strong, smart and skilled--a place where others can qualify for the Darwin Awards. The surface is the most varied possible. The only missing ingredients are mud and water crossings. There are ledges, deep sand, loose rock, hardpack, slickrock, gigantic rock rubble, and every combination of these you can imagine.
This ride is extremely dangerous! Despite the inherent danger of the exposed cliff, the Portal Trail is the emergency hatch to and from Poison Spider Mesa and the Gold Bar Rim in case of a storm or accident. Two deaths almost closed the trail in 1998. If we are to believe the BLM, one more is all it is going to take. This is the most challenging, beautiful, and awe inspiring mountain bike ride on earth. Treat it like it's sacred. Respect it. Love it. Care for it. Most of all, fear it."
