America’s national parks are enduring a punishing stretch of environmental crises. The Grand Canyon, a crown jewel of the system, was hit by devastating floods last week that damaged nearly 40% of its sole water pipeline and triggered search-and-rescue operations. That disaster came on the heels of wildfires that scorched the park’s northern edge earlier in 2025, marking two major natural calamities in less than a year.

But the Grand Canyon is not alone in its struggle. Yosemite National Park is currently battling wildfires that have forced the closure of Highway 140, a key artery for visitors. Now, the park faces a different kind of threat — not from nature, but from a private developer seeking to carve out a piece of its land.

Kingsbarn Realty Capital, a real estate firm, has been in discussions with the National Park Service (NPS) for nearly a year over a proposed transfer of roughly 700 feet of parkland. The company owns an 83-acre parcel called Hazel Green Ranch, located just outside Yosemite’s western boundary. This property, historically significant as a stagecoach route into the park from the late 1800s to the early 1900s, lost its role as an entrance when automobiles replaced horse-drawn carriages.

Kingsbarn wants to build a road across the 700-foot strip to connect Hazel Green Ranch to Big Oak Flat Road, a major thoroughfare inside Yosemite. Currently, access to the ranch requires an 11-mile drive on forestry roads through Stanislaus National Forest. The developer argues that a direct road would reduce traffic on those Forest Service roads, ease congestion around Yosemite, and benefit the environment.

In a statement to Fortune, the Department of Interior, which oversees the NPS, said there has been “no political pressure to reach a predetermined outcome” and that “no final decisions have been made.” The department emphasized that any land exchange or access proposal would be subject to all applicable federal laws, regulations, and policies, including environmental review and public notification. “If a proposal advances, the Department will follow established procedures to ensure appropriate coordination, transparency and public involvement consistent with federal law,” the statement read.

Kingsbarn’s attorney, Lanny Davis, told Fortune that the company has held more than a dozen meetings with the NPS to find a legal path forward. “We’ve been negotiating the mechanics of a land exchange that is legal,” Davis said. “A purchase of a right of way or even the actual property from the Park Service is not legal by a private developer. The only thing that’s a legal way of doing it is an exchange.”

The legal landscape for transferring public park land to private hands is murky. The NPS’s FAQ site states that only government entities can acquire surplus federal property for park and recreational use through its Federal Lands to Parks program. However, the Department of Interior’s Bureau of Land Management notes that it “does occasionally sell parcels of public land” when land-use planning deems it appropriate and in the public interest. Such sales require the land to meet one of three criteria: it is scattered and hard to manage, no longer needed for its original purpose, or disposal would serve important public objectives like community expansion or economic development.

Davis argues that the Hazel Green Ranch road project meets the public interest test. “Hazel Green has agreed to build and maintain this road at its expense to meet all federal, state, and local standards,” he said. “It is good for the environment, keeps cars off the Forest Service roads, and helps ease congestion in, and around, Yosemite National Park. Clearly, these benefits are in the public interest.”

As the negotiations continue, Yosemite’s wildfire crisis underscores the park’s vulnerability. The proposed land exchange could set a precedent for private development within national park boundaries, a move that conservationists are likely to scrutinize closely. For now, the fate of that 700-foot strip rests on legal interpretations, environmental reviews, and the balance between public access and private gain.
