Much of Yellowknife is easily walkable. From downtown to Old Town is about 2km, or a 25-minute walk.
Yellowknife City Transit (867-873-4693; adult/child $2/1.50) runs three routes. Route 1 serves Old Airport Rd and downtown. Route 2 connects downtown and Old Town. The summer-only Rte 3 melds the above two routes together. Most buses run every half hour, roughly 6:30am to 7:30pm Monday to Friday, and for just a few hours on Saturday.
With its prominent landmarks, Yellowknife is easy to navigate. Parking around Franklin Ave is metered; free spots are a few blocks away on side streets. Ask at the visitors center about the three-day parking pass for tourists.
Cabs are plentiful. Fares are $3 plus $1.60 per kilometer. The biggest company is City Cab (867-873-4444).
