Major US national parks are experiencing severe strain this summer as record-breaking visitor numbers collide with significant staffing shortages and infrastructure backlogs. Reports from sites like Zion, Yellowstone, and Yosemite describe traffic conditions comparable to urban rush hours, with parking lots reaching capacity before mid-morning.
According to an analysis by the National Parks Conservation Association (NPCA), the National Park Service (NPS) lost nearly 25% of its permanent staff in 2025. These personnel reductions, compounded by deferred maintenance estimated at $24 billion, have led to the removal of timed-entry reservation systems in several parks. While the NPS claims this strategy increases access, critics argue it has returned parks to a state of unpredictable congestion and reduced service quality.
The surge is driven by a long-term trend of increasing visitation, heavily influenced by social media popularity. However, the crowding remains concentrated; the ten busiest parks accounted for more than half of all visits in 2025. Travel experts suggest that visitors seeking a better experience should look toward lesser-known sites, such as North Cascades or Capitol Reef, to avoid the gridlock currently plaguing iconic destinations.
