Cascade ID to Afton WY: A Scenic Road Trip Guide

The journey from Cascade, Idaho to Afton, Wyoming spans roughly 200 miles, following US-95 south and then US-20 east across a dramatic transition from the forested valleys of central Idaho to the high desert plains of western Wyoming. This route is known for its sudden elevation changes: from Cascade's 4,800 feet, the road climbs to over 7,000 feet at Teton Pass before descending into Afton at 6,200 feet.

Drivers often remark on the stark change in landscape—from the lush pine forests around Cascade Lake to the sagebrush-covered flats near the Wyoming border. The drive takes about 4.5 hours without stops, but most travelers stretch it to a full day to enjoy the numerous viewpoints and small towns.

The most direct route uses US-95 South from Cascade to New Meadows, then US-55 South to McCall, and then Idaho State Highway 55 to Banks, where you can either continue on ID-55 to Boise or take US-95 South to Weiser and then US-20 East to Afton. The latter avoids Boise traffic and saves about 30 minutes.
