An all-mountain bike with around 150mm of travel is recommended for tackling the aggressive terrain effectively.

A great trail that will challenge intermediate riders. Off The Grid (OTG) is loaded with obstacles, drops, roots and rock gardens. Stay right at the split if you want to continue OTG and left if you want to switch to NOTG Trail – which is the more flowy option.
