Paw Paw Tunnel | Hagerstown

Paw Paw Tunnel is a 3,118-foot-long canal tunnel located in Allegany County, Maryland, USA.

It is a significant engineering feat of the early 19th century, designed to allow canal boats to pass through a mountain ridge.

Visual Characteristics

The tunnel is constructed primarily of cut stone blocks, with brick lining in certain sections. Its exterior is largely obscured by the surrounding forested terrain. The entrance portals are arched, with rough-hewn stone framing. Inside, the tunnel is a dark, damp passage with a roughly circular cross-section, supported by stone masonry.

Location & Access Logistics

Paw Paw Tunnel is situated approximately 15 miles west of Hagerstown, Maryland, along the C&O Canal Towpath. Access is via the Paw Paw Tunnel Trailhead, located off Maryland Route 51. Parking is available at the trailhead. The tunnel is accessible by foot or bicycle from the C&O Canal Towpath. No public transport directly serves the tunnel.

Historical & Ecological Origin

Construction of Paw Paw Tunnel began in 1836 and was completed in 1850. It was built as part of the Chesapeake and Ohio Canal system. The primary purpose was to overcome the geological barrier presented by the Wills Mountain ridge, enabling westward expansion of canal traffic. The tunnel passes through sedimentary rock formations.

Key Highlights & Activities

Walking or cycling through the tunnel is the primary activity. Visitors can experience the dark, cool interior and imagine the passage of canal boats. The C&O Canal Towpath offers opportunities for hiking and biking. Fishing is permitted in the adjacent canal waters.

Infrastructure & Amenities

Restrooms are available at the Paw Paw Tunnel Trailhead. Shade is provided by the surrounding forest. Cell phone signal is intermittent within the tunnel and along the towpath. No food vendors are located directly at the tunnel; provisions should be brought from nearby towns.

Best Time to Visit

Daylight hours are recommended for visiting the tunnel to ensure visibility. Spring and autumn offer moderate temperatures for outdoor activities. The canal water level is generally stable, so tide considerations are not applicable.

Facts & Legends

During construction, workers encountered significant geological challenges and labor disputes. A persistent local anecdote claims that the tunnel is haunted by the spirits of workers who died during its construction, though no verifiable records support this.
