The highway passes through dense forests of Western ghats of India.

The NH-766 passes through 19.7 km Bandipur National Park and Wayanad wild life sanctuary.

The Karnataka government banned night traffic from 9 P.M. up to 6 A.M. through the road passing through Bandipur National Park as conservationists argued that it is disturbing the wildlife.

It is closed for 2-wheelers from 6 P.M. to 6 A.M.[2] The alternate road to use during night hours is to leave NH 766 at Kalpetta and proceed to Mysore through Mananthavady, Kutta, Gonikoppal, and Hunsur.

This alternate route is much longer and completely bypasses Sulthan Bathery, Gundlupet and Nanjangud.
