The US-97-A highway offers a delightful driving experience, particularly for those seeking scenic beauty. This route hugs the western bank of the Columbia River, providing continuous, stunning vistas. It's a key artery connecting several charming towns in Chelan County, including Entiat and Chelan itself. Travelers often choose US-97-A for its picturesque landscapes and a more relaxed pace compared to the main US-97 highway on the opposite side of the river.

Knapp's Hill Tunnel is a brief, yet memorable, feature along this byway. While short, its presence adds a unique element to the drive. Visitors should be aware of the possibility of falling rocks, as noted by one traveler, and exercise caution. The tunnel itself is more of a passage than a destination, but it's a point of interest that enhances the overall journey through this beautiful region.

When planning your trip, remember that US-97-A is distinct from US-97. Navigating between them is possible via bridges, but understanding their separate paths is crucial for itinerary planning. The west side route, with the tunnel, offers a different perspective of the Columbia River valley, often characterized by its orchards and vineyards in the surrounding areas.
