7 Most Rattlesnake-Infested Areas In Oregon (Stay Alert)
As warm weather approaches, outdoor activity increases-and so does the likelihood of encountering wild animals, like rattlesnakes. Oregon is home to one venomous snake species, the western rattlesnake (Crotalus oreganus), but that doesn't mean sightings are rare. Because of that, it's best to know places they tend to call home. To help you out, we listed the six most rattlesnake-infested areas in Oregon to avoid.
There are actually two subspecies of the rattlesnake found in different regions of the state, which can make avoiding them a bit more difficult. The Northern Pacific rattlesnake (Crotalus oreganus oreganus), which has a muted, earthy coloration is most often seen in central and northeastern Oregon, where it inhabits woodlands and rocky canyon areas. The Great Basin rattlesnake (Crotalus oreganus lutosus), has lighter yellowish-tan coloring and is more common in the dry, open landscapes of the southeast, including sagebrush plains and desert basins. Both snakes reach lengths of about 30 to 36 inches and can often be found soaking up the sun on rocky outcrops and south-facing slopes.
Although they have a dangerous reputation, these rattlesnakes are not usually aggressive and typically avoid people. They rarely bite unless they feel threatened. However, since wild animals are unpredictable, knowing rattlesnake infested areas in Oregon is never a bad thing if you live there or are planning to visit. After all, there are certain locations where encounters are more likely to happen and you have a higher chance to run into a rattlesnake. That's why it's important to stay aware and cautious when exploring the outdoors whether you're alone or with a group of people.
So, where are rattlesnakes found in Oregon? Tons actually live in tourist areas and in popular hiking spots. Below are six places where you are most likely to see a in western rattlesnake in Oregon.
Lower Deschutes River Canyon
One rattlesnake-infested place in Oregon is Lower Deschutes Canyon. This stunning natural area, carved by the Deschutes River as it flows 252 miles toward the Columbia River, features rugged terrain and diverse ecosystems. Near the bottom of the canyon, the landscape becomes increasingly rocky and dry, creating the perfect environment for western rattlesnakes to thrive. These snakes are especially drawn to the canyon's rocky outcrops, sun-warmed slopes, and secluded crevices, making it one of the top rattlesnake habitats in Oregon, especially during early spring and late fall during warmer mornings and evenings.
Smith Rock State Park
With over 1,800 climbing routes and elevations between 2,600 and 3,200 feet, it's easy to see why Smith Rock State Park is so beloved. Though besides views of stunning cliffs overlooking the Crooked River, hikers are also likely to see rattlesnakes in this central Oregon location.
According to the state park, western rattlesnake sightings are more common there than in other parts of Oregon particularly from April to October. These venomous snakes can be found on trails like Wolf Tree Trail and new dry, rocky areas near the river as well.
One of the most recent reports of a hiker being bit there was in 2024, who was flown to a hospital in Bend to be treated, according to KTVZ News.
Steens Mountain and Malheur National Wildlife Refuge
If you want to avoid rattlesnakes, the Oregon Natural Desert Association notes that western rattlesnakes love this Oregon area, as the river edges and rocky outcrops provide the perfect habitat for them. You will find them on the lower elevations along the western approach road on Steens Mountain, as well as in the terrain.
Owyhee Canyonlands
In the southeastern corner of Oregon lies Owyhee Canyonlands. It happens to be one of the most snake populated places of Oregon. Because this is where the Owyhee River cuts through hundreds of miles of canyon country, Great Basin rattlesnakes and reptile like horned lizards thrive there.
Besides the Owyhee River, another rattlesnake hotspot there is Leslie Gulch. This rattlesnake concentrated area even has a river called Snake River where hikers often report rattlesnake sightings.
Wallowa-Whitman National Forest
If you're outside of La Grande, the Wallowa-Whitman National Forest may be an area you want to explore. However, be aware that this picture-worthy destination is also crawling with highly venomous rattlesnakes. In fact, the 2.4 million acres is one of the most rattlesnake-filled areas in Oregon. So, keep that in mind if you visit.
John Day Fossil Beds National Monument
When it comes to Oregon rattlesnake locations, John Day Fossil Beds National Monument is one. The most active period to encounter Northern Pacific rattlesnakes is from April through October.
Table Rocks, Rogue Valley
Where are rattlesnakes most common in Oregon? Just outside Medford, are two volcanic mesas north of the Rogue River called Upper Table Rock and Lower Table Rock where you'll find them. In fact, while hikers love going there to see the wildflowers bloom, the pretty scenery can be dangerous as its a high rattlesnake zone and where Oregon's only venomous reptile in southwestern Oregon lives: the western rattlesnake. They are frequently spotted in the tall, grassy slopes, so its best to stick to the trails when you're there March through May, as that's when the snakes are most active. By doing so, you'll most likely be at a safer distance from where they are roaming.

While rattlesnake bites are rare, it's important to act quickly and stay calm if one does occur. After all, knowing the right steps can make all the difference while you, someone you know or a pet is waiting for medical help. Here is what Poison Control advises you do:
- Call 911 and seek help from poison center experts by phone at 1-800-222-1222.
- Don't panic and stay as calm and still as possible to slow the spread of venom.
- Don't use outdated first aid remedies: no tourniquets, ice, or cutting the wound and sucking out the venom. None of these "treatments" help and most of them make things worse.
- Keep the arm or leg (usual sites for snakebite) at the level of the heart.
- Remove any jewelry, watches, or tight clothing from the bite area.
- Dowash the area gently with soap and water.
