About visiting Harriet Tubman Underground Railroad

Harriet Tubman Underground Railroad National Historical Park is a National Historical Park in MD and one of the system's hidden, low-traffic units, drawing about 15,000 recreation visits in 2025. Visitation has held fairly steady over the past decade. Crowds concentrate sharply by season: July is the busiest month at about 1.6× the park's average month, while January is the calmest at roughly 0.4× — a 4-to-1 swing between high and low season. Roughly 37% of the year's visitors arrive in the three summer months of June, July and August alone, so timing a trip outside that window is the single biggest lever on how crowded the park feels. If avoiding people matters most, January offers the thinnest crowds of the year, though you'll trade some warmth and daylight for the solitude. Daylight ranges from about 9.3 hours in midwinter to 14.7 hours near the summer solstice, which shapes how much ground you can cover in a day. These crowd figures are drawn from 2023–2025 of National Park Service visitor-use records, and are updated as new monthly data is released.

Park overview

Harriet Tubman was a deeply spiritual woman who lived her ideals and dedicated her life to freedom. She is the Underground Railroad’s best known conductor and before the Civil War repeatedly risked her life to guide 70 enslaved people north to new lives of freedom. This new national historical park preserves the same landscapes that Tubman used to carry herself and others away from slavery.
