I didn’t think much about snakes when I first visited Yosemite in California. I was more focused on waterfalls, granite cliffs, and filling pages in my sketchbook with trees and bears. But after stumbling across a gopher snake on a quiet trail near Tuolumne Meadows, I started paying more attention to the wildlife at ground level. Snakes in Yosemite aren’t something to be afraid of – but they’re definitely something to be aware of.
And not just for our own safety. Being mindful of where snakes live and how they behave is just as important for the sake of the snakes themselves. Many of them are easily injured by unaware hikers or even killed out of fear. These reptiles are an essential part of the park’s ecosystem, and honestly, they’re fascinating to observe. Seeing one in the wild is a real privilege.
If you’re planning to hike, sketch, or camp anywhere in the park, especially during the warmer months, it’s worth taking a few minutes to learn what kinds of snakes live in Yosemite, how to identify them, and how to stay safe and respectful – to them and yourself.

Key things to know about snakes in Yosemite
Here are the three things I think are most helpful to know before heading out on the trail:
- You’re unlikely to see a rattlesnake, but it’s good to know how to spot one. They’re shy, avoid humans, and are most active in summer.
- Not all snakes in Yosemite are venomous. In fact, most are harmless, like the common garter snake or gopher snake.
- Watch where you step or sit, especially near logs, rocks, or sunlit trails. Most snake encounters happen when they’re basking or hiding.
Types of snakes in Yosemite
There are several species of snakes in Yosemite, and while you probably won’t see most of them unless you’re specifically looking, it’s good to be familiar with the main ones. That way, if you do spot one, you’ll know how to respond – and maybe even enjoy the moment.
Northern Pacific Rattlesnake
This is the only venomous snake in the park, and it tends to stick to lower elevations. I’ve never seen one while sketching, but I have heard the occasional rattle in dry, grassy areas in the foothills. They have a triangular head, heat-sensing pits, and of course, a rattle at the end of their tail. If you give them space, they usually move on quietly.
Rattlesnakes are often misunderstood. They don’t go out of their way to bite people, and their warning rattle is actually their way of avoiding confrontation. It’s a kind of courtesy in the animal world: a signal that you’re too close. Backing off calmly is all you need to do.
Gopher Snake
These are easy to mistake for rattlesnakes because of their coloring and behavior. I once saw one flatten its head and shake its tail in the leaves – which sounded enough like a rattle to make me jump. Totally harmless, though. They’re non-venomous and often hang out in open meadows or forest edges.
If you’re quiet and still, you can sometimes watch them flick their tongues and slowly glide through the grass. For me, sketching them from a distance has been a peaceful experience.
Common Garter Snake
If you see a snake near water or a meadow, it’s probably this one. They’re colorful, fast-moving, and completely harmless. I’ve sketched these a few times near small creeks – they’re beautiful when the light hits their stripes.
These snakes are excellent swimmers and tend to be quite active in the morning. If you’re nature journaling near water, they’re a real treat to watch.
For more examples of how I draw these kinds of animals, I shared some techniques in how to draw animals.
When and where you’re likely to see them
Snakes are most active from late spring through early fall, especially on warm days. They like to bask on trails, rocks, and roads during the morning or late afternoon. I’ve seen them most often in open, sunny areas around 4,000 to 6,000 feet elevation.
If you’re staying in Yosemite Valley, Wawona, or the foothills, your chances of seeing a snake go up. Higher elevations like Tuolumne have fewer sightings but it’s not impossible.
They tend to avoid heavily trafficked trails, but if you’re in a quieter area, especially near water or rocky outcrops, it’s worth keeping your eyes open. And don’t forget to look down now and then – not just to avoid stepping on something, but because you might be lucky enough to see one basking in the sun.
Staying safe and respectful
I think a lot of fear around snakes comes from not knowing what to expect. Most snakes in Yosemite want nothing to do with humans. I’ve found that by staying alert and giving them space, it’s easy to avoid problems.
- Stay on the trail. This reduces the chance of accidentally stepping on a basking snake.
- Look before you sit or put your hands somewhere. Especially around rocks and fallen logs.
- Don’t try to pick up or move a snake. Even non-venomous ones can bite if threatened.
- Educate the people you’re with. Kids especially benefit from knowing that snakes aren’t “bad” animals – they’re just doing their thing.
If you do see a rattlesnake, just slowly back away. They don’t want to waste venom on you and usually only strike when cornered. Remember that most bites in the U.S. happen when someone tries to pick up or harass a snake.
Respect goes both ways in nature. We tread lightly so they can continue to thrive.
Why snakes matter to the ecosystem
As someone who loves drawing wildlife and thinking about ecological connections, I find snakes fascinating. They control rodent populations, feed birds and mammals, and contribute to the natural balance of the Sierra Nevada ecosystem. Without them, the populations of mice, voles, and other small mammals would skyrocket, which could damage plant communities and increase the risk of disease.
They also serve as prey for hawks, eagles, and coyotes. In other words, snakes are right in the middle of Yosemite’s food web, quietly keeping the ecosystem in check.
You can read more about other wildlife areas in California to get a broader sense of how places like Yosemite fit into the larger picture.
I’ve also written about wildlife in Joshua Tree National Park if you’re curious how different desert and mountain habitats compare.
Nature journaling tip
If you like to draw or keep a nature journal, sketching snakes is a great way to slow down and observe. I recommend drawing from photos or at a distance if you’re lucky enough to spot one in the wild. I usually start with the curve of the spine, then build up the body and patterning.
I often jot down notes about the habitat, time of day, and behavior I see. Those little observations become part of the memory and deepen my appreciation for the animal.
