Alamo Heights (78209) holds two fenced off-leash dog parks, four verified on-leash trail systems, and a walkable street grid connecting residents to parks that most newcomers find only by word of mouth. This guide covers all of them: where they are, what they offer, which ones flood after a storm, and what the summer heat means for the timing of your dog’s walk.
Alamo Heights is a separate incorporated city, not a San Antonio neighborhood. It has its own government, police department, and school district. For dog owners, that distinction is more than a civic footnote. The streets, parks, and walking culture here give Alamo Heights a character that makes it one of the most genuinely walkable communities in the metro for people with dogs.
Key Facts: Dog Walking in Alamo Heights (78209)
- Off-leash parks in 78209: Two separate fenced areas within the zip code. The Bark Park of Alamo Heights: 103 La Jara, sunrise to sunset, seven days, separate large/small dog sections. The Dog Park at Olmos Basin Park: 103 Alamo Heights Blvd, fenced with shade trees.
- Safe walk window (June through September): Before 8 a.m. or after 7 p.m. on summer afternoons. Asphalt can burn paws in under 60 seconds when surface temperatures peak. Specific temperature data is in the heat section below.
- Shaded trail options near 78209: Judson Nature Trails (246 Viesca, Alamo Heights, 1.5 miles, natural surface), Olmos Basin Park (500 Devine Rd, 1.37 miles paved plus approximately 5 miles dirt), Headwaters Sanctuary at the University of the Incarnate Word (4503 Broadway, 1.4-mile loop, free, 24 hours).

Off-Leash in 78209: Two Parks Most Residents Don’t Know About
Alamo Heights has two separate fenced off-leash dog parks within walking distance of each other, both inside 78209. Most residents know about one. Fewer know about both.
Before You Go: Bark Park Practicalities
The on-site water trough at the Bark Park of Alamo Heights is shut off from roughly December through January. Bring your own water in winter. Saturday mornings are the busiest stretch, especially after 9 a.m. If your dog gets stressed in crowds, a Tuesday morning is a quieter visit. The new crushed-granite parking lot on the Normandy right-of-way (24 spaces) made weekend parking much more manageable than it used to be.
The Bark Park of Alamo Heights (103 La Jara)
The Bark Park of Alamo Heights is located at 103 La Jara, Alamo Heights, TX 78209, near the baseball fields at the corner of Alamo Heights Blvd and La Jara. The Bark Park of Alamo Heights is community-run, not city-owned. Local dog owners in 78209 created it, maintain it through donations, and volunteer their time to keep it usable.
The park operates sunrise to sunset, seven days a week. Two separate fenced sections serve large and small dogs, which matters if your smaller dog gets overwhelmed by high-energy larger breeds. Large oak trees provide genuine shade even in July. A water trough is on-site from spring through fall, though it is shut off during winter months. Worth bringing your own water in December and January.
Parking has historically been limited, but the city approved improvements: 24 spaces on an extended Normandy right-of-way, finished with crushed granite. That’s a meaningful upgrade for a park that fills up on Saturday mornings.
One thing worth knowing: the longtime volunteer who coordinated maintenance relocated out of state in late 2025. The city of Alamo Heights is discussing whether to take over formal management or relocate the park to the Judson Nature Trails area. The Bark Park of Alamo Heights is still operating and the community is actively engaged in its future. This is a neighborhood that takes its parks seriously.

Dog Park at Olmos Basin Park (103 Alamo Heights Blvd)
The second off-leash option in 78209 is the fenced dog park within the larger Olmos Basin Park complex, at 103 Alamo Heights Blvd, San Antonio, TX 78209. This park is separate from the Bark Park of Alamo Heights on La Jara, and the two are often confused.
The Dog Park at Olmos Basin Park is fenced, shaded, and has a water trough. It operates adjacent to the City of San Antonio park system, distinct from the Alamo Heights city limits. Alamo Heights residents within 78209 can choose between the Bark Park of Alamo Heights and the Dog Park at Olmos Basin Park based on crowd levels, grass conditions, or route preference on any given morning.
On-Leash Walks Worth Making: Trails and Parks Near 78209
For structured walks with your dog on a leash, Alamo Heights and its immediate surroundings offer more variety than most residents have tried.
Olmos Basin Park (500 Devine Rd)
Olmos Basin Park sits just outside Alamo Heights city limits but is directly accessible on foot from most of 78209. The park runs daily from 5 a.m. to 11 p.m.
Two trail systems run through the park. Approximately 1.37 miles of paved concrete path follow Olmos Creek, mostly shaded, with a mix of dirt and paved sections. A second network of unpaved dirt trails winds through the floodplain, adding up to roughly 5 miles of additional options for dogs that need longer outings.
One thing every regular knows: Olmos Basin Park is a designed flood-detention structure, built after the catastrophic 1921 San Antonio flood to capture and hold stormwater. After significant rain, the low-lying sections of the trail become impassable, sometimes dramatically so. After any major storm, check conditions before heading to the lower trails. This is the kind of thing you learn once before planning a walk there, not something to find out mid-walk with a wet dog.
Leash required on all trails.
Judson Nature Trails (246 Viesca, Alamo Heights)
The Judson Nature Trails are located inside the Olmos Flood Basin along Hondo and Olmos creeks, at 246 Viesca, Alamo Heights, TX 78209. The trailhead is a 5 to 10 minute walk from most of the Alamo Heights core. The trails run 1.5 miles over natural-surface dirt and rock, through bottomland habitat that stays shaded and cooler than asphalt routes even on warm mornings. No motorized vehicles use the trails. Restrooms are available at the trailhead.
The natural surface is the key advantage in summer. Dirt and rock don’t absorb and radiate heat the way asphalt does. A 7 a.m. walk on the Judson Nature Trails is a meaningfully different experience from a 7 a.m. walk on Broadway, even at the same air temperature.
The trail runs along creek-bottom habitat that draws a surprising range of birds: red-shouldered hawks, barred owls, and cardinals are common sightings. Worth mentioning to any dog owner who hasn’t been.
Dog-friendly with leash required.
Headwaters Sanctuary at the University of the Incarnate Word (4503 Broadway)
Headwaters Sanctuary at the University of the Incarnate Word (UIW) sits at 4503 Broadway, San Antonio, TX 78209, near the southern edge of Alamo Heights. The main loop runs 1.4 miles, easy grade, shaded throughout. Free admission, open 24 hours. Dogs are welcome on leash.
The Blue Hole on the property is the source spring of the San Antonio River, a legitimate local landmark worth seeing once. The sanctuary itself is quiet and somewhat removed from the Broadway traffic, which makes it a different experience than the parks closer to the Alamo Heights core.
Mahncke Park and Brackenridge Park
Mahncke Park, at 3400 N New Braunfels Ave, San Antonio, TX 78209, offers a 1.0-mile easy loop directly accessible on foot from southern Alamo Heights. Mature tree canopy, quieter traffic than Brackenridge, and a neighborhood feel that works well for a routine daily walk. It connects to Brackenridge Park trails for owners who want to extend the outing.
Brackenridge Park, at 3700 N St Mary’s St, San Antonio, TX 78212, is about a mile from Alamo Heights proper. At 343 acres, it’s a longer destination, heavily shaded, with connections to the San Antonio River trail system. Leash required. Worth the trip when you want more space than the neighborhood parks provide.
The Heat Window: What Every Alamo Heights Dog Owner Should Know Before July
San Antonio’s summer heat is not a vague concern. San Antonio’s July average high is 95.5 degrees F. August averages 96.6 degrees F. The summer heat index peaks at 116 to 118 degrees F.
The 7-Second Pavement Test
Place the back of your hand flat on the pavement and hold it there. If you pull away before seven seconds, the surface is too hot for your dog’s paws. Asphalt in direct sun hits approximately 135 degrees F when the air temperature is just 86 degrees F, and paw burns can begin in under 60 seconds at 120 degrees F. This test costs nothing and takes one second to perform. Do it before every summer walk.
What that means for the pavement under your dog’s paws is more specific than most people expect. When air temperature is 86 degrees F, asphalt in direct sun reaches approximately 135 degrees F. Burns can begin in under 60 seconds at 120 degrees F surface temperature.
The 7-second test gives you a field check: place the back of your hand flat on the pavement and hold it there. If you cannot hold it for seven seconds, the surface is too hot for your dog’s paws. This test is cited by the AKC, the ASPCA, and Pet Sitters International.
The safe walk window from late May through September runs before 8 to 9 a.m. and after 7 to 8 p.m. On a Tuesday in August, that morning window closes before 9 a.m. For a household where both people leave by 7:30, the window is already gone before the workday starts. That math is where professional dog walking becomes less of a convenience and more of a safety issue.
The natural-surface trails at Judson Nature Trails and the shaded paths through Olmos Basin Park run cooler than street-level asphalt routes. If your timing is tight, those trails extend the usable window slightly.
What a Professional Dog Walker Actually Does Differently in This Neighborhood
A dog walker who works regularly in Alamo Heights and Terrell Hills operates with a specific body of knowledge that doesn’t come from a map.

Fire Ant Warning: What to Watch for on Trails
Red imported fire ants are active year-round in Bexar County. Peak mound-building runs March through May. New mounds appear along grass edges, under park benches, and at shaded trail margins. If your dog suddenly lifts a paw, licks frantically, or snaps at the air, move away from the area immediately. Those signs appear before symptoms escalate, and quick exit is the difference between a minor incident and a vet visit.
The trail edges at Judson Nature Trails and Olmos Basin Park are where mounds show up most often. Walk center-trail when possible in spring.
Cathy’s Critter Care walkers know the Olmos Basin Park trail conditions after rain. The team routes dogs onto shaded residential streets and grass rather than staying on exposed asphalt when Broadway pavement heats up fast by mid-morning in July. They also know where fire ant mounds appear in spring along the unmaintained trail edges at Judson Nature Trails and Olmos Basin Park.
Fire ants are worth understanding. Red imported fire ants (Solenopsis invicta) are active throughout Bexar County year-round, with peak mound-building in spring, from March through May. New mounds appear in sheltered spots: along grass edges, under park benches, at the margins of shaded trails.
A dog sniffing along a trail edge can reach a mound before the owner registers the danger. Fire ants don’t sting once; they grip with their mandibles and sting repeatedly. A disturbed mound sends dozens of ants swarming within seconds.
A trained walker recognizes the early signs of stings: sudden paw lifting, frantic licking, snapping at the air. Those signs appear before symptoms escalate, and knowing to exit the area quickly is the difference between a minor incident and a vet visit.
There is also a reliability argument. Cathy’s Critter Care runs a team of 20 sitters, with 365-day availability. A solo walker who gets sick means a missed walk. A team has a backup. For a working household in 78209 where the dog’s midday walk is not optional, that consistency is worth more than it sounds on paper.
Cathy Vaughan has been providing pet care in Alamo Heights since 1998. Her team is background-checked, bonded, and insured. In 2018, Pet Sitters International named her Pet Sitter of the Year. That credential comes from the industry’s primary professional association, and it reflects what 28 years of operating in one market looks like.
