The Walkway is installed in an "L" shape configuration. From the picture and scenes of its rigging, I hope that most of your concerns addressed. Securing ropes, safety nets and supporting harness etc.

The walkway is built using tall trees on a steep slopes. The furthest point this walkway is suspended from ground is 100 feet.

You could walk the bridge alone or with your companions.  But each length of walkway should not be occupied by more than 3 persons at any one time.

This picture shows half of the walkway and the "L" shape formations.

The visit to this Canopy Walk and the use of the walkways are subjected to the rules and regulations set up by the Forest Research Institute.  Do call them for more details.
