The Lakes to Locks Passage in the United States and the corresponding Route du Richelieu in Canada form a scenic byway network located in northeastern New York and southern Quebec.

This network is part of a historically significant transportation route linking upstate New York with the Canadian province of Quebec.

The region's history is reflected in the diverse influences of French, English, and Dutch settlers, which can be seen in the architecture and cultural heritage of the communities along the rivers, waterfalls, and lakeshores.

This waterway constitutes one of North America's earliest interconnected water systems, playing a significant role in the historical development of the United States and Canada.

It connects various historic, natural, cultural, and recreational sites along its route, including: In 1992, the State of New York designated the Champlain Trail as a New York State Scenic Byway, recognizing its significance in providing access to the scenic, historic, cultural, natural, and recreational resources of Lake Champlain and its surrounding communities.

In January 2000, local communities in Clinton, Essex, and Washington counties completed a Corridor Management Plan (CMP) for the Champlain Trail.
