Route best - Best to take a guide to the takeoff. Avoid going to the Arch and go around the back to above the arch. or try from previous explorers as follows -
Short and sharp, above the famous burdah arch.
Pass the arch and continue up like 50meters (a short difficult \'climbing\' move : a 10m piece of rope may be helpful to climb first without the bag then bring the glider up with the rope)
