Hidden along County Road 112 in Cisco, Texas, sits a forgotten treasure that most road trippers zoom right past without a second glance.
The Old Zoo Nature Trails transform what was once a bustling 1920s zoo into a hauntingly beautiful hiking area where nature has reclaimed crumbling cages and weathered stone enclosures.
Travelers seeking off-the-beaten-path adventures flock here for the unique blend of history, mystery, and rugged terrain that makes every step feel like a journey through time. This isn’t your typical Texas hike.
It’s a scavenger hunt meets history lesson meets rock-scrambling adventure all rolled into one unforgettable experience.
A Zoo Frozen in Time Since the 1920s

Walking through these trails feels like stepping into a time capsule that nobody bothered to seal properly. Built during the roaring twenties when Cisco was a booming oil town, this zoo attracted families from all over Texas who wanted to see exotic animals without traveling to big cities.
Imagine flappers and Model Ts rolling up to see lions, bears, and monkeys tucked into rocky hillside enclosures that used natural caves and cliffs as part of the habitat design.
The zoo mysteriously closed decades ago, and the reasons remain shrouded in local legend and speculation that keeps history buffs endlessly fascinated. Some say financial troubles doomed the attraction while others whisper about more dramatic circumstances that forced the gates to shut forever.
What remains today are bent metal bars, crumbling stone walls, and the ghostly outlines of where animals once paced and played.
Volunteers work tirelessly to maintain the trails and preserve this unique piece of Texas history for future explorers to discover and appreciate. The sense of abandonment mixed with careful preservation creates an atmosphere that’s equal parts melancholy and magical, making every visit feel deeply personal.
You can almost hear the echoes of children’s laughter and animal calls drifting through the trees if you stop and listen closely enough.
The Great Medallion Treasure Hunt

Before you hit the trails, snap a photo of the totem pole near the entrance that displays ten animal medallions representing creatures that once called this zoo home. This isn’t just a cute photo op but your treasure map for one of the most engaging scavenger hunts you’ll ever experience on a hiking trail.
Each medallion is hidden somewhere along the trails, mounted near the former enclosures where those specific animals lived all those decades ago.
Finding all ten requires sharp eyes, a good sense of direction, and a bit of luck since some medallions have sadly been stolen by thoughtless visitors over the years. Most hikers report finding between six and eight, which still feels like a major victory worth celebrating with a victory dance.
The hunt adds an extra layer of excitement to your hike, especially if you’re traveling with kids who need extra motivation to keep moving.
Each discovery feels like unwrapping a small gift from the past, connecting you directly to the zoo’s history in a tangible and thrilling way. The medallions feature beautiful metalwork depicting lions, bears, monkeys, and other animals that once captivated visitors generations ago.
Don’t forget to check the map posted at the entrance, which shows approximate locations and helps you plan your route strategically for maximum medallion-finding success.
Boulder Scrambling Paradise

Forget flat, boring trails that put you to sleep with their predictability and lack of challenge or visual interest whatsoever. The Old Zoo Nature Trails deliver serious rock-scrambling action that engages your whole body and keeps your adrenaline pumping throughout the entire adventure.
Massive boulders jut from the hillside, creating natural climbing opportunities that range from beginner-friendly to moderately challenging depending on which route you choose.
The same rock formations that once formed the backdrop for animal enclosures now serve as your personal playground for channeling your inner mountain goat.
Climbing atop these ancient stones rewards you with stunning views of the surrounding landscape, Lake Cisco shimmering in the distance, and a genuine sense of accomplishment.
Kids absolutely love the physical challenge, though parents should definitely supervise younger climbers on the trickier sections.
Spider Rock Trail leads to a particularly impressive formation topped with a lion medallion that makes the climb totally worth every bead of sweat. The uneven terrain and elevation changes provide a workout that feels more like play than exercise, which is exactly how hiking should feel.
Wear closed-toe shoes with good grip because tennis shoes on smooth rock can get slippery, especially if morning dew still clings to the surfaces when you arrive early.
Creepy Cages That Tell Stories

Nothing prepares you for the eerie feeling of standing inside an old animal enclosure where bears or big cats once lived out their days. The bent and rusted cage bars, some twisted as if by superhuman strength, spark imagination about the animals that tested these boundaries long ago.
Modern sensibilities make these tiny spaces heartbreaking to witness, reminding us how far animal welfare standards have evolved since the early twentieth century.
Graffiti covers many surfaces, which some visitors find disrespectful while others view as layers of history marking different eras of human interaction with this space.
The vandalism does detract from the natural beauty, but it also creates an undeniably urban-exploration vibe that attracts photographers and adventure seekers specifically.
Cave-like enclosures carved into natural rock faces show incredible ingenuity in zoo design, using the landscape itself as part of the habitat structure.
Peering into these dark spaces, you can almost visualize the animals that once sheltered there from Texas heat and the curious gazes of Depression-era families.
The combination of natural beauty and human-made decay creates a hauntingly photogenic environment that looks incredible in every season and lighting condition.
Respect the space by leaving only footprints, even if others before you didn’t show the same courtesy to this irreplaceable historical site.
Lake Views and Dam Drama

Your hike comes with bonus scenery courtesy of Lake Cisco and its impressive dam structure that dominates the landscape with industrial-age engineering prowess. The trails sit on the back side of the dam, offering unique vantage points that most lake visitors never experience from the main access areas.
Water glimmers through the trees as you hike, providing cooling visual relief on hot Texas days when the sun beats down relentlessly.
Fishing spots near the trails attract anglers hoping to land bass, catfish, or whatever else swims in these waters, adding another activity option to your visit. The combination of water, rocks, woods, and historical ruins creates a diverse landscape that keeps your eyes constantly discovering new details and perspectives.
Just remember to respect private property boundaries clearly marked in certain areas, as neighboring landowners understandably protect their spaces from trespassers.
The dam itself makes an impressive backdrop for photos, especially during golden hour when the light hits the water and concrete structure just right.
Seasonal water levels change the lake’s appearance dramatically, so visiting multiple times throughout the year reveals completely different scenery and moods.
Bring binoculars if you’re into birdwatching because the water attracts numerous species that make this area part of their migration routes or permanent territory throughout the year.
Trail Difficulty and What to Expect

The trails cover about 1.5 miles total with a loop option that takes most people one to two hours depending on exploration enthusiasm and medallion-hunting dedication.
Elevation changes keep things interesting without being brutally difficult, though summer heat definitely increases the challenge factor exponentially compared to cooler seasons.
Shaded wooded sections provide relief, but you’ll also traverse exposed areas where the Texas sun shows absolutely no mercy to unprepared hikers.
Some paths are beautifully maintained by dedicated volunteers while others show signs of overgrowth, particularly thorny bushes that grab at shorts and bare legs viciously.
Long pants and closed-toe shoes aren’t just recommendations but essential gear if you plan to explore beyond the main loop into secondary trails.
Uneven footing, rocky steps, and scrambling sections mean this isn’t the right choice for people with serious mobility issues or very young children who tire easily.
That said, families with elementary-age kids regularly tackle these trails successfully and have absolute blast doing so together as a team. The terrain variety means you can customize your experience, sticking to easier paths or seeking out the most challenging scrambles depending on your group’s abilities.
Bring plenty of water because there’s none available on the trails, and Texas heat combined with physical exertion will dehydrate you faster than you expect.
Pet-Friendly Adventures with Cautions

Many visitors successfully bring their dogs along for the adventure, though you’ll need to exercise extra caution regarding broken glass scattered in some areas, particularly near the entrance.
Reviews mention glass concerns frequently enough that it’s worth taking seriously, even though most of the trails stay relatively clear thanks to volunteer cleanup efforts.
Keep your pup on a leash both for safety and to respect other hikers who might not appreciate surprise dog encounters on narrow trail sections.
The rocky terrain and uneven surfaces don’t bother most dogs, especially breeds built for outdoor adventures, but tiny or elderly dogs might struggle with the scrambling sections.
One reviewer even brought their cat in a harness, proving that adventure knows no species boundaries when you’ve got the right gear and attitude.
Just remember that thorny bushes don’t discriminate between human and animal skin, so protect your furry friend’s paws and body from painful encounters.
Water bowls aren’t available on-site, so pack enough for both you and your four-legged hiking partner to stay properly hydrated throughout your exploration.
The combination of scents, sights, and interesting terrain makes this an enriching experience for dogs who need more mental stimulation than typical neighborhood walks provide.
Check your pet thoroughly for ticks and stickers after your hike because Texas vegetation loves to hitchhike home on unsuspecting fur.
Amenities That Enhance Your Visit

A decent parking area provides easy access without the frustration of circling endlessly or hiking miles just to reach the trailhead entrance.
Public restrooms across from the main gate mean you don’t have to plan your entire day around bathroom availability, which honestly makes or breaks many outdoor adventures.
During some periods, porta-potties equipped with toilet paper serve visitors, earning enthusiastic praise from reviewers who appreciate this thoughtful touch tremendously.
Picnic tables scattered throughout the area, including one specifically located in the old zoo section marked on trail maps, invite you to pack lunch and make a full day of your visit.
A playground near the parking area keeps younger children entertained before or after the hike when their energy levels don’t quite match the trail demands.
The flagpole area features a delightful painted rock snake created by visitors who add their own decorated stones, creating a collaborative art project that grows continuously.
A QR code posted at the entrance allows you to donate directly to trail preservation efforts, supporting the volunteers who maintain this space for public enjoyment.
These amenities transform what could be a rough wilderness experience into a comfortable family outing that doesn’t require extensive planning or survival skills.
The combination of facilities and wild spaces strikes a perfect balance that welcomes both hardcore hikers and casual nature lovers equally well.
Seasonal Considerations and Best Times

Summer visits require serious heat management strategies including early morning starts, abundant water supplies, and realistic expectations about physical limits in oppressive temperatures.
The trails open at 6 AM daily, making dawn hikes possible when temperatures stay relatively reasonable and wildlife activity peaks for better nature observation opportunities.
Fall and spring offer ideal conditions with moderate temperatures that let you explore comfortably without melting into puddles of regret halfway through.
Winter hiking provides its own unique charm with bare trees revealing views that summer foliage obscures completely, plus you’ll likely have the trails almost entirely to yourself.
Seasonal water level changes at Lake Cisco alter the scenery dramatically, rewarding repeat visitors with fresh perspectives on familiar landscapes throughout the calendar year.
Weather can shift quickly in Texas, so check forecasts and prepare for sudden temperature changes, especially during spring when conditions fluctuate wildly.
Rainy periods make trails muddy and slippery, increasing difficulty and potentially making rock scrambling dangerous rather than merely challenging and fun. The trails close at 9 PM, giving you plenty of daylight during longer summer days to explore thoroughly without rushing through your adventure.
Weekdays tend to be quieter than weekends if you prefer solitude over socializing with fellow hikers on the trails and at medallion locations.
Why This Place Deserves Your Road Trip

Cisco itself might not scream destination hotspot, but that’s precisely what makes discovering this hidden gem feel so rewarding and special to adventurous travelers.
The town’s history as a booming oil center followed by economic decline mirrors countless Texas communities, yet few have such a unique attraction preserved for public enjoyment.
Combining your trail visit with lunch at a local non-franchise restaurant, as several reviewers recommend, supports the community while adding authentic flavor to your adventure.
The 4.7-star rating from nearly 300 reviews speaks volumes about how this place exceeds expectations for visitors willing to venture off major highways.
Multiple reviewers drove one to four hours specifically to experience these trails, testament to the site’s unique appeal that you simply cannot replicate anywhere else.
The combination of history, mystery, physical challenge, scavenger hunt excitement, and natural beauty creates a multifaceted experience that satisfies diverse interests simultaneously.
Volunteers and the City of Cisco deserve massive credit for transforming what could have been a forgotten eyesore into a celebrated attraction that brings visitors and positive attention to the area.
The trails represent community pride, historical preservation, and environmental stewardship working together to create something truly special and worth protecting.
Pack your bags, charge your camera, and point your GPS toward Cisco because this abandoned zoo adventure absolutely belongs on your Texas bucket list immediately.
