In Texas, unique destinations often attract those looking for a glimpse into the past, and the mysterious abandoned zoo near Cisco is no exception. Once a lively tourist attraction where families gathered, this site now presents a haunting landscape as nature steadily overtakes the remnants of its former life.
Visitors find themselves drawn to the blend of history and intrigue, a setting that feels almost like the backdrop of a classic murder mystery. The empty animal enclosures and overgrown paths invite exploration, making this location a notable spot for those interested in Texas history and eerie adventures.
The Early Years and Evolution of Cisco’s Abandoned Wildlife Park
The roots of the now-abandoned zoo in Cisco, Texas, stretch back to the early 1930s. Positioned near Lake Cisco Dam and established during a time of civic growth and outdoor entertainment, the Cisco Zoo was considered a marvel of its era. Local residents and travelers alike found themselves drawn to Cisco, less than two hours west of Fort Worth, eager to witness the beauty and novelty of exotic animals up close.
Notable animals and features in the 1930s:
- Bears: Among the first to call Cisco Zoo home.
 - Peacocks: Brilliantly colored birds that roamed the park.
 - Monkeys: Entertained families and added a lively atmosphere.
 - Deer and other animals: Rounded out the collection.
 - Animal medallions: Decorative elements celebrating the diversity of creatures once on display.
 
A unique aspect of this site was its array of attractions beyond animal exhibits. There was a massive public concrete swimming pool—often described as one of the largest in the country—that spanned nearly the size of two football fields.
Guests could also explore a mini amusement park, cool down at an icehouse, and even spend the night in stone cabins designed for visitors. These features created an environment where families could spend an entire day, making memories in a blend of natural and manufactured beauty.
| Feature | Description | 
|---|---|
| Exotic animals | Monkeys, bears, flamingos, deer, birds | 
| Swimming pool | At its peak, one of the world’s largest | 
| Amusement facilities | Ice rink, amusement park, stone cottages | 
| Landscape | Lush gardens and tree-lined paths | 
Despite its popularity, the zoo’s fortunes changed in the late 1930s. A mysterious incident claimed the life of a bear by poisoning, and not long after, a deer died under suspicious circumstances. These events led to concern among the community and cast a shadow over the park. In the wake of these controversies, many animals were relocated to other facilities.
By the end of the 1930s, the zoo was permanently closed. Nature began to reclaim the abandoned site. Enclosures and buildings deteriorated, and gardens grew wild. The enormous pool remained in use for several decades, finally falling into disrepair by the late 1970s. Now, the ruins stand as a reminder of Cisco’s vibrant past and its brief moment as a local center of wonder and beauty.
Exploring the Old Zoo Paths
The Old Zoo Nature Trails offer visitors a unique experience walking through the reclaimed grounds of the former zoo near Lake Cisco. This hiking area covers about 1.5 miles and is mostly easy to navigate, though some sections can be a bit uneven or steep. Wearing sturdy shoes is recommended for the cracked paths and occasional rocky spots.
While following the trail, hikers notice remnants of the zoo’s original structures. Rusted cages, the outlines of old enclosures, and fences now surrounded by thick vegetation are visible along the way. Nature has taken over much of the site, with vines climbing former animal habitats and moss spreading across stone walls. These sights create a mix of historical curiosity and the feeling of being somewhere hidden and remote.

Points of interest found along the way include:
- The stone cabins where zoo workers and visitors once stayed
 - An old concrete swimming pool, now filled with algae, with a high diving platform still standing
 - Various animal enclosures, now empty and silent
 
For families and younger hikers, a scavenger hunt has become a popular addition on the Old Zoo Nature Trail. Participants search for ten animal medallions placed around the hiking paths, each tucked away near notable features from the zoo’s past. This activity encourages exploration and keeps children engaged as they trek through the overgrown grounds.
Visitors should plan for an outing of one to two hours, depending on how much time they spend pausing to observe the old ruins or take pictures. There are several side trails and offshoots that allow for a longer or more varied hike, appealing to those who enjoy wandering off the main route. Since there are no facilities or shops nearby, it’s advisable to bring water and snacks for the trip.
| Feature | Notes |

| Trail Length | ~1.5 miles | 
| Difficulty | Easy, but uneven in places | 
| Main attractions | Old zoo structures, stone buildings, overgrown scenery |
