No official step-free route is published for Channagiri Fort. A vehicle reaches town and the hill base, but the ruined summit requires a climb over uneven ground.
Build a ground-level day
Use roadside viewpoints toward the fort, a safe firm approach at Shanti Sagara and the accessible parts of Santhebennur. The Pushkarini steps themselves are not step-free.
Ask before travel
Accessible toilets, ramps and assistance are not documented by the official visitor pages. Confirm current conditions locally and travel with a driver who can wait rather than relying on uncertain onward transport.
