The Sawback Trail follows the rugged Sawback Range from the town of Banff to Lake Louise over a distance of 74km (about 45 miles). There are side trails to be discovered too which would increase the distance.
Note: some of the trails are not well marked except for the main trail and the horse trail. It is recommended that hikers carry a compass and obtain the relevant maps for the areas they will be hiking in from Gem Trek . Topographic maps: 82 O/4, 82 O/5. An excellent preview map from ParksCanada on Banff National Park's backcountry trails, campsites including information on the different users of the trails can be seen here. It will help in planning your outdoor excursions.

This bird is often seen around camp sites and picnic areas where it scavenges for scraps of food. Though its main food source is pine nuts.
At the 38km mark the hiker will arrive at the junction with the Luellen Lake Trail, where anglers can fish. Although the lake has not been stocked with fish for years, there are still enough for anglers and osprey.
