Starting at Avalanche Lake, the ride is a flat to slight climb for 6 miles (9.7 km) alongside a rushing creek and in the midst of epic mountainous views. The following 2 miles (3.2 km) is a climb to The Loop, and we encourage pushing through to get past it for an unmatched valley view, emerging just around the corner. Elevation continues to pick up as you climb the next 10 miles to Logan Pass, gaining around 2,400 feet in elevation. Note:  June 15th to September 2nd Bike Restrictions between Logan Creek to Logan Pass (uphill) are in effect from 11 am to 4 pm. The earlier the season, the farther away from Logan Pass the plow crews will be. Keep in mind, Avalanches and Bears are a unique hazard to biking the GTTSR. Be aware of your surroundings at all times and use caution. Need Bear Spray? Rent it Here!
