12 National Parks With Fewer Bugs In September

There’s a universal truth to adventuring outdoors: bugs can ruin the mood faster than forgetting your hiking boots. But fear not, September is right around the corner. And it is the golden child of getaway months, ushering in cooler breezes, fewer pests, and a crispness in the air that practically begs you to hit the trails.

Imagine standing in a sunlit meadow where the only buzz you hear comes from the faint hum of the wind, not an incessant mosquito choir demanding your blood donation. With September’s gentle touch, the sizzling summer heat retreats, leaving behind landscapes brushed with amber and gold, ready for your wandering feet.

From the towering sequoias of California to the rugged peaks of Montana, we’re spotlighting national parks where bugs take a back seat next month, letting you soak in all the natural wonder… sans pesky interruptions.

Got your own secrets to bug-free bliss? Toss them in the comments on MSN.


Rocky Mountain National Park, Colorado

Situated in the heart of the Rockies, this park is a haven for anyone craving crisp, bug-free mountain air. Here, the pine-scented breeze flirts with your senses while golden aspens dance against a backdrop of rugged peaks.

September graciously rolls in, chasing off those bloodthirsty mosquitoes like a stern campground ranger. And elk bugles echo through the valleys, adding a soundtrack that’s both haunting and majestic.

Trek along the Dream Lake trail, where reflections of snow-dusted peaks ripple in icy-clear water, and tell me mosquitoes could handle this chill (don’t worry, they can’t.) If you combine the mosquito-busting weather with the sheer grandeur of the Rockies, you’ve got the ultimate recipe for a fall escape that leaves your spirits soaring higher than Longs Peak.

Yosemite National Park, California

Yosemite in late summer; think fewer lazily circling bugs and more time marveling at granite giants like El Capitan. Turns out, the dry air isn’t just a win for your hair; it’s bad news for mosquitoes, who apparently prefer moisture over monoliths.

Meander through the fragrant cedar forests of Yosemite Valley as the Merced River sparkles under the late-afternoon sun, reflecting ribbons of golden light. At dusk, as you stand in the shadows of Half Dome, you’ll feel an otherworldly stillness that those winged nuisances can’t ruin.

Plus, with the crowds thinning out post-summer, you might just get a moment of solitude to appreciate nature’s cathedral in peace (or at least without slapping your own arms).

Zion National Park, Utah

September in Zion is a revelation. With cooler nights finally muscling out the summer heat, those whining gnats and buzzing mosquitoes decide to pack it in early. Lucky you.

With rust-red cliffs glowing under the softer sunlight, the park beckons you to wander through the Narrows or tackle Angel’s Landing. But don’t worry, the only thing biting at you now is the crisp autumn breeze.

And as you stand amidst the towering cliffs, you might be struck by one simple thought: this place belongs on a postcard (but thankfully, not on a mosquito’s travel itinerary).

Bryce Canyon National Park, Utah

Fancy walking in an amphitheater of crimson and pink hoodoos without needing to swat at mosquitoes? Bryce Canyon delivers. At over 8,000 feet, it’s fall, and insects can’t hack the altitude or the drop in temperatures.

Stroll along the Rim Trail, where each jagged spire seems to glow under the slanted autumn sunlight. Pine trees pepper the air with a sharp, woody scent, and the occasional rustle might just be a mule deer quietly pondering its own path.

And brace yourself for stargazing nights so clear it feels like you’ve crash-landed in another galaxy, where no mosquito nets are required.

Grand Canyon National Park, Arizona

The Grand Canyon in September? Pure magic. Dry, cooler weather arrives like a well-timed relief pitcher, giving you permission to gawk at the sheer enormity of the canyon without that pesky “buzz.”

The air carries a hint of desert warmth, laced with sagebrush and a metallic tang from the sunbaked rocks. And sunrise over the South Rim unveils cascading hues of orange, red, and gold. But guess what’s not there to photobomb your moment? Mosquitoes.

Hike the Bright Angel Trail or simply linger on the rim, letting the grandeur sink in. It’s a classic bucket-list destination, but September’s bug-free charm is the underrated bonus you didn’t know your trip needed.

Great Sand Dunes National Park, Colorado

The tallest sand dunes in North America aren’t just a feast for the eyes; they’re also a bug-free blessing, thanks to the dry, autumn air. Imagine trudging up 750-foot dunes under a sky so blue it could make a sapphire jealous, feeling gritty sand shift beneath your feet, and not a bug in sight.

The wind whispers through the valley, kicking up grains that sparkle like tiny diamonds in the sun. And nights here are an astronomer’s dream, showcasing stars so bright they almost seem unreal.

The ancient San Luis Valley holds stories, from the Native American legends about the dunes’ formation to the whispers of early settlers searching for fortune. And without pesky insects to ruin your stargazing or sandboarding, it’s just you, the dunes, and the unspoiled wonder of it all.

Glacier National Park, Montana

September in Glacier is a swan song for liquid summer and, thankfully, for mosquito season too. The crisp nights usher those winged mischief-makers into hibernation mode while you soak up the last golden days of this alpine paradise.

During your visit, meander along the Going-to-the-Sun Road, where jagged peaks rise against an impossibly blue sky, and waterfalls tumble down moss-carpeted slopes. And the scent of pine needles and damp earth follows you on trails around Lake McDonald.

When the local wildlife (grizzlies, mountain goats, and maybe that one friend who’s always lagging) steal the show, the absence of biting distractions feels like nature’s final gift of the season.

Yellowstone National Park, Wyoming

Yellowstone in cooler weather means fewer mosquito swarms, and who wouldn’t be thankful for that? Here, steaming geysers bubble like natural cauldrons, and plumes of sulfur-scented steam curl into the brisk autumn air.

Along trails lined with golden aspen, you might catch sight of bison snorting out clouds of breath into the cold morning mist. The park’s rugged beauty really shines when the pesky bugs take a break, no swatting required as you wander past rainbow-hued hot springs or the edge of Yellowstone Lake.

And don’t forget the history; this is America’s first national park, after all. It’s as though the park itself, born of volcanic fury and shaped by time, is inviting you to explore its raw, untamed grandeur, uninterrupted by tiny winged assassins.

Grand Teton National Park, Wyoming

Chilly mornings in the Grand Tetons bring a sharpness to the air that awakens every sense. Frost clings to the meadows as you lace up your boots and gaze at the towering, sawtooth peaks bathed in first light. And the early hours not only chill your nose but also slow down those six-legged nuisances that thrive in warmer months, clearing the way for uninterrupted wandering.

Consider floating along the Snake River, its clear waters reflecting the mountain spires, or watch elk bugle in wide valley fields during a visit.

Here, nature is both stark and immense, leaving you small and spellbound, but content in knowing that the only swarming you’ll encounter is from the sheer magnificence of your surroundings.

Under the towering giants of Sequoia National Park, the crisp autumn air carries the nostalgic scent of pine and cool earth, while buzzing insects are noticeably absent thanks to the changing weather.

Standing in the shadow of General Sherman, the world’s largest tree, is a humbling experience. Its gnarled bark, aglow in the filtered sunlight, echoes centuries of history (it was sprouting long before your grandparents’ grandparents were born). And the quiet serenity of the groves is broken only by the occasional scurry of squirrels and the whisper of falling leaves.

Explore marble caves or gaze down into plunging canyons without swatting at a single fly; just pure, uninterrupted awe beneath skies boasting that signature California gold.

Death Valley National Park, California

Death Valley throws its weight behind extremes, and bug-free bliss is no different. How could anything survive in the land of blistering salt flats and rolling, sand-filled barrenness where temperatures flirt with record-breaking heights?

Autumn’s cooler charm makes the park more approachable, but insects? They’ve checked out entirely. Wander through the surreal landscape of Badwater Basin, where cracked salt stretches to the horizon, or capture the blazing hues of Artist’s Palette, where the hills shimmer in colors you almost don’t believe are real.

The silence here has a weight, a gravity that sinks deep into your bones. And without bugs to interrupt your thoughts, Death Valley becomes less an assault on the senses and more a raw exhibition of nature’s extremes.

Arches National Park, Utah

Utah’s Arches National Park, where rock formations bend and curve in seemingly impossible ways, offers not just a geological wonderland but insect relief, too. The dry landscape leaves little room for stagnant water or bugs to thrive.

Step (or carefully stumble) across rusty red trails winding beneath Delicate Arch, a structure so iconic it proudly graces Utah’s license plates. The sharp scent of desert sage mixes with the dry air, and you’ll hear the crunch of sand beneath your boots as you marvel at how wind and water shaped this surreal masterpiece.

Time slows as the golden hour drapes the arches in fiery light, etching the park into your memory. And with no mosquitoes to steal attention as the day winds down, it’s the perfect time to stay for the stars putting on their show in the pitch-perfect darkness.
