South Park Drive closes to cars for migrating newts on November 1—but it remains open to people walking dogs. Here is how to share the route without putting a dog or wildlife at risk.
Yes. East Bay Regional Park District says South Park Drive remains open to people walking dogs while it is closed to motor vehicles from November 1, 2026, through March 31, 2027. Keep your dog close and away from every newt; Salt Hound recommends using a leash for the entire road during migration season. If a dog mouths or eats a newt, contact a veterinarian, emergency hospital or animal poison-control service immediately, and do not induce vomiting unless a veterinary professional tells you to.
What changes on November 1?
The seasonal closure applies to motor vehicles on South Park Drive in Tilden Regional Park. People may still walk, bicycle and bring dogs on the road. The park district closes the road so California newts can move between forest habitat and Wildcat Creek with less risk from traffic.
Migration activity is most likely when the ground is damp—during rain, after rain or under heavy fog. A clear morning does not guarantee the road is clear of newts, and their small size and muted coloring can make them difficult to see against wet pavement and leaf litter.
The vehicle closure does not suspend Tilden’s normal dog rules. Dogs must be leashed in parking lots, picnic and developed areas, wherever signs require it, and within the first 200 feet of a trailhead. Elsewhere, park rules still require control. For this particular route, Salt Hound’s safer recommendation is simpler: keep the leash on for the whole walk during newt season.
Why should dogs stay away from newts?
Newts have a defensive toxin that can be dangerous if a dog mouths or eats one. The risk is not a reason to avoid Tilden; it is a reason to prevent contact. Do not let a dog sniff closely, lick, paw at or pick up a newt, even if the animal is motionless.
People should not handle or move the newts either. The park district prohibits collecting or disturbing wildlife. If a newt is on the road, stop, give it space and let it continue at its own pace.
How can you make the walk safer?
- Use a short, fixed leash. A long line or fully extended retractable leash can put a dog beside a newt before you see it.
- Scan several yards ahead. Look carefully along the road edges, in leaf litter and across damp patches.
- Slow down after rain or fog. Moist conditions are when migrating newts are most likely to be moving.
- Keep food and play off the pavement. Tossed treats or toys can send a dog’s mouth toward something hidden on the road.
- Turn around if you cannot prevent contact. There is no prize for completing the route when visibility, crowding or leash handling makes the walk unsafe.

What should you do after possible contact?
If you think your dog mouthed or swallowed a newt, move away from the animal and contact your veterinarian, the nearest emergency veterinary hospital or an animal poison-control service immediately. Do not wait for symptoms to decide whether to call, and do not try to make your dog vomit unless a veterinary professional specifically instructs you to do so.
Be ready to explain what happened, when it happened and what you observed. Veterinary teams and poison specialists can decide what evaluation or treatment is appropriate for the individual dog. Salt Hound’s Dog Help Desk can help you find the right next resource, but it does not replace urgent veterinary care.
What should you check before leaving home?
Tilden has other projects and temporary closures that can affect parking, trail access and the best way to reach South Park Drive. Check the current Tilden Regional Park page on the day of your visit. A seasonal vehicle closure and a separate construction or fuels-reduction closure are different things, and one should not be used to infer the other.
Reader action: Before a November-through-March visit, pack a short leash, check the current park alerts and save your veterinarian’s and nearest emergency hospital’s contact information.
