Nearly all of Edmonton [1]’s best hotels are located downtown. Other concentrations of motels can be found along Gateway Boulevard (Hwy. 2 from the south) and scattered along Stony Plain Road in the west. The towns of Leduc and Nisku have several motels close to Edmonton International Airport.
Other options include bed-and-breakfasts, two backpacker lodges, and camping (just five minutes from downtown, or in campgrounds west, east, or south of the city).
