Trail Overview

Transcontinental Network

The American Discovery Trail (ADT) is a meticulously planned system of recreational trails and roads that collectively form a comprehensive, non-motorized, coast-to-coast pathway across the mid-section of the United States. It accommodates hikers, bicyclists, and equestrians across most of its extensive route.

Scale and Scope

Spanning an impressive 6,800 miles (10,900 km), the ADT is recognized as the sole non-motorized, coast-to-coast trail in the nation. It features distinct northern and southern alternates, passing through major hubs like Chicago and St. Louis, thereby offering diverse experiences.

Termini and Routes

The trail's eastern terminus is situated at Cape Henlopen, Delaware, on the Atlantic Ocean, while its western terminus is at Limantour Beach, California, on the Pacific Ocean. The northern route covers approximately 4,834 miles (7,780 km), and the southern route extends for about 5,057 miles (8,138 km).

Geographic Extremes

Highest Point

The trail reaches its apex at Argentine Pass in Colorado, situated at an elevation of 13,207 feet (4,025 meters) as it traverses the Rocky Mountains.

Lowest Point

Conversely, the trail descends to its lowest point in the California Delta, between Isleton and Antioch, California, registering at -17 feet (-5.2 meters) below sea level.

Diverse Terrain

The ADT navigates through a remarkable variety of landscapes, including 14 National Parks and 16 National Forests, showcasing the diverse natural beauty of the United States.

Interconnected Pathways

National Trails Integration

The American Discovery Trail serves as a crucial connector within the national trails system. It integrates with or runs concurrently along sections of five National Scenic Trails, ten National Historic Trails, and twenty-three National Recreation Trails, creating a vast network for exploration.

Major Trail Overlaps

Significant portions of the ADT coincide with other major long-distance trails, including the North Country Trail, the Buckeye Trail, the Continental Divide Trail, and the Colorado Trail, offering opportunities for extended journeys and diverse trail experiences.

Endurance Feats

Pioneering Hikers

The trail has been completed by numerous dedicated individuals. Notable early thru-hikers include Joyce and Pete Cottrell, who completed segments over two years, finishing in 2003. Marcia and Ken Powers were the first couple to complete the trail in a single continuous walk (2005). Mike Daniel achieved the first continuous hike of the full 6,800 miles (2007-2008), and Briana DeSanctis became the first woman to complete the full 6,800 miles solo (2022-2024).

Equestrian Achievement

Demonstrating the trail's versatility, Matt Parker completed the entire equestrian route on horseback between May 2003 and November 2005, highlighting the ADT's suitability for various forms of non-motorized travel.
