TL;DR: Bear Hollow Cave is an 8-acre nature preserve in Bella Vista, Benton County, Arkansas, acquired by The Nature Conservancy in 1998 through donation and protected as habitat for an endangered cave crayfish found nowhere else but here and two other caves worldwide (The Nature Conservancy, nature.org, accessed August 2026).
A Protected Natural Landmark in Bella Vista
Bear Hollow Cave is an 8-acre nature preserve located in Bella Vista, Benton County, Arkansas. The Nature Conservancy acquired the property in 1998 through donation. It is protected because it is one of only three caves in the world known to harbor the endangered Benton County cave crayfish, Cambarus aculabrum — a level of biological rarity that drives strict limits on access.

Bear Hollow Cave: Access Restrictions
The preserve is open to the public for viewing the entrance and surrounding woodlands, but the cave's underground passages are gated and closed to the public; interior access is limited to guided Nature Conservancy field trips and cleanup events (The Nature Conservancy, nature.org, accessed August 2026). This is a landmark to see from the outside, not a cave you can tour or explore on your own — plan a visit accordingly.
Nature Conservancy staff have carried out ongoing stewardship at the site, including graffiti removal, entrance-gate repair and preventing vehicle trespass (The Nature Conservancy, nature.org, accessed August 2026). Those efforts keep the site safe and intact for the rare species it protects, and for the woodlands visitors are welcome to see.
Bear Hollow and the Back 40 Trailhead
'Bear Hollow' is also the name of one of the Back 40 trail system's eight primary trailheads in Bella Vista, alongside Blowing Springs, Metfield Pump Track, Metfield Cart Barn, Buckingham, Lake Ann, Bella Vista Community Church and Tower (City of Bella Vista, bellavistaar.gov, accessed August 2026). The Back 40 comprises roughly 40 miles of soft-surface, singletrack mountain-biking and hiking trail on Bella Vista's east side, open daily 5 a.m. to 10 p.m. (City of Bella Vista, bellavistaar.gov, accessed August 2026). It's a useful landmark for orienting yourself on that side of the trail network, whether or not you plan to visit the cave itself. The Back 40 mountain-bike trail system opened its first 15-mile section in August 2016, funded by a $3 million grant from the Walton Family Foundation to NWA Trailblazers, which built the trails (Talk Business & Politics, August 2016), and today it spans trails across three skill levels, from a beginner loop under a mile long to advanced routes like The Ledges (City of Bella Vista, bellavistaar.gov, accessed August 2026).
Because Bear Hollow Cave is protected land owned and managed by The Nature Conservancy, it is not a property available for purchase or development — its long-term status is conservation, not real estate. Anyone drawn to the area for its natural scenery should look at homes elsewhere in Bella Vista rather than assume anything about this specific parcel. The trailhead that shares its name is a public access point on the trail system, distinct from the cave preserve itself, and both are worth understanding separately before you plan a visit.

Bella Vista's population reached an estimated 34,518 as of July 1, 2025, up from 30,104 residents at the April 1, 2020 Census, according to the U.S. Census Bureau QuickFacts — a simple headcount, not a signal about any particular property.
