Glacier visitation by year.

Glacier by the year.

Each row is the park's total recreation visits for that calendar year, drawn from the official NPS Visitor Use Statistics Data Package, 2025 (Statistic = TRV, summed from monthly to annual). The full 1979-2025 history is shown — 47 years. Bar widths are proportional to the all-time peak; the orange bar marks the peak year and the teal bar marks the lowest year in the full window.

What the trend says

Glacier's annual recreation visits over the full 1979-2025 dataset show a long, lumpy climb constrained by the park's notoriously short Going-to-the-Sun Road season. The dataset begins in 1979 at roughly 1.45 million — also the lowest year in the full 47-year series — and the 1980s ran in the 1.5-to-1.85 million range with a decade mean near 1.66 million. The 1990s held in the 1.7-to-2.1 million band; visits crossed 2 million for the first time in 1993 but the park spent most of the decade just below that line.

The 2000s settled in the 1.9-to-2.2 million range. The 2010s broke the pattern decisively: visits crossed 2.5 million in 2014, 2.9 million in 2016 with the NPS Centennial, and the all-time peak in the full 1979-2025 series is 3.31 million in 2017 — the high water mark in the dataset and an early sign of the late-2010s outdoor-recreation surge. The 2010s decade mean was 2.86 million, more than 70% above the 1980s decade mean. The 2020 pandemic year fell to 1.70 million — the deepest single-year dip in the modern series and below every reading since the early 1990s — driven by NPS's late opening and reduced operations.

Recovery since 2020 has been notable but uneven. 2021 introduced a ticketed-entry pilot for Going-to-the-Sun and visits rebounded to 3.08 million; 2022 fell back to 2.91 million, 2023 to 2.93 million, then 2024 climbed to 3.21 million and 2025 settled at 3.14 million — the third-highest reading in the dataset but still below the 2017 record. The 47-year mean is roughly 2.20 million; 2025 sits about 940,000 visits above that long-term mean but about 170,000 below the 2017 peak. Read across the full window, the structural story is a slow 1980s-1990s climb into a 2-million floor by the 2000s, a 2010s breakout to the 3-million plateau, a single deep pandemic-year trough, and a managed-entry recovery just under the 2017 record. Year-to-year movement on top of the current plateau is dominated by Going-to-the-Sun Road operations (vehicle reservation rules, plowing timing, wildfire smoke), not by underlying demand shifts.

Methodology

Annual recreation visits come from the official NPS Visitor Use Statistics Data Package, 2025 on NPS IRMA Stats. The statistic shown is Recreation Visits — the NPS visitor-count category that excludes Tent Campers, Backcountry Campers, and Recreation Visit Hours. Annual totals are computed by summing the twelve monthly TRV (Total Recreation Visits) values for each year. The window displayed here is the full 1979-2025 history available in the NPS dataset.
