Major construction projects in the Chisos Basin area of Big Bend National Park are scheduled to begin May 1, 2026, triggering a full closure of the basin while work is underway, park officials said.
The projects, funded through the Great American Outdoors Act, include the replacement of the aging Chisos Mountains Lodge and a comprehensive overhaul of the basin’s water distribution system. Construction is expected to last approximately two years, with completion targeted for summer 2028.
Once work begins, the Chisos Basin area will be closed to visitor entry. The closure will include Basin Road, lodging units, the Basin Campground, restaurant, National Park Service visitor center, camper store and all trails within the basin.
Park officials emphasized that the closure is limited to the Chisos Basin and that the rest of Big Bend National Park will remain open year-round. The park spans more than 800,000 acres and includes hundreds of miles of scenic drives, river access points, campsites and more than 150 miles of hiking trails that will remain accessible.
The start date was set for early May to align with the park’s seasonal visitation trends, as visitor numbers typically decline with the onset of hotter temperatures.
Through April 30, 2026, facilities in the Chisos Basin — including the visitor center, campground, camper store and trail system — are expected to remain open. Visitor services such as food offerings and retail operations will continue to be provided by the park’s concessioner during that period, and lodging availability will be managed separately.
The lodge replacement project addresses long-standing structural issues with the existing facility, which was built in 1964 on unstable clay soils. Over time, foundation movement has caused extensive damage to the building’s structure and systems, making continued maintenance unsustainable.
Plans call for a new lodge constructed within the existing footprint, designed to reflect the historic Mission 66 architectural style while incorporating modern improvements. The updated facility is expected to include expanded visitor amenities, improved operational efficiency and design features such as solar energy capability and enhanced outdoor viewing areas.
At the same time, crews will replace aging water infrastructure serving the basin, including a pipeline system dating back to the 1950s. The upgrades are intended to reduce water loss, improve reliability and support long-term resource conservation in the desert environment.
As construction progresses, park managers will periodically evaluate which portions of the basin can be safely reopened.
Additional updates and project information are available through the National Park Service.
