Summary (tl;dr)

Yosemite National Park is experiencing a significant surge in visitors, leading to widespread congestion and overcrowding, primarily due to the National Park Service's decision to eliminate the park's timed-entry reservation system for 2026.

Essential Background

For several years, Yosemite National Park, like many other popular national parks, utilized a timed-entry reservation system, first implemented in 2020 due to COVID-19 and then continued to manage increasing visitor numbers and reduce congestion. This system had successfully helped to spread out visitation and mitigate traffic jams and overcrowding at popular sites.

The Full Story

Following a review of 2025 traffic and parking data, the National Park Service (NPS) announced in February 2026 that Yosemite would no longer require timed-entry reservations for the 2026 season, asserting that a season-wide reservation was not the most effective approach. Since this change, the park has seen a sharp rise in attendance. March 2026 visitor numbers reportedly increased by approximately 45% compared to the same period in the previous year, making it the busiest March since 2016. Visitors are now reporting extensive entrance delays, some lasting up to 90 minutes, packed parking lots often reaching capacity before midday, and overcrowded conditions on trails and at viewpoints, particularly on weekends and holidays. This surge has also led to concerns about illegal parking in meadows and along roadsides, and some visitors have likened the experience to visiting a theme park like Disneyland.

Why It Matters

The current visitor surge raises significant concerns for both the visitor experience and the long-term preservation of Yosemite's natural resources. Overcrowding can diminish the quality of visits, with reports of "shoulder to shoulder" crowds and "chaos" in popular areas. Environmental advocates and park officials express worry about potential damage to the park's fragile ecosystems due to increased foot traffic, illegal parking, and strain on infrastructure. The situation underscores the ongoing challenge national parks face in balancing public access with the need to protect these treasured landscapes for future generations.
