As spring settles across San Bernardino County, residents heading outdoors may begin to notice a familiar seasonal presence returning to local trails: rattlesnakes.
Across inland Southern California, rattlesnakes typically emerge from winter dormancy around March and remain active through October, according to the California Department of Fish and Wildlife. Activity tends to peak during the spring mating season—April through May—and again in early fall. As temperatures rise, these reptiles often shift their movement to cooler parts of the day, meaning early mornings, evenings, and nighttime are when encounters are more likely.
In communities like Redlands and surrounding areas, local trails and open spaces are shared habitats. The Redlands Conservancy has reminded residents that popular outdoor destinations double as wildlife corridors, particularly this time of year.
That includes frequently visited locations such as Herngt 'Aki' Preserve, San Timoteo Nature Sanctuary, Teddy’s Trail, and Creekside Trail, where sightings have already been reported this season.
“Trail users, whether on two feet, four feet, or two wheels, need to stay alert,” the Conservancy shared in a recent community message. “Rattlesnakes may be using the same paths you are.”
Wildlife officials emphasize that the presence of rattlesnakes is a natural part of the region’s ecosystem and not a reason to avoid outdoor recreation. Instead, they recommend taking simple, practical precautions consistent with guidance from the California Department of Fish and Wildlife:
- Wear long pants instead of shorts
- Keep dogs leashed and nearby
- Watch trail edges and shaded areas
- Listen for the distinctive rattle
- Give any snake ample space and turn back if necessary
- Stay on designated trails
In one recent instance shared locally, hikers encountered a rattlesnake that remained on the trail for more than 10 minutes. Rather than attempt to pass, they chose to turn around—avoiding a potentially dangerous interaction.
Encounters like this serve as a reminder that throughout San Bernardino County, outdoor spaces are active habitats. With awareness and caution, residents can continue to safely enjoy the region’s trails during the spring and beyond!
