Colorado summers make it hard to stay indoors. Between scenic foothill trails, shaded creek paths, and mountain overlooks, Englewood residents have no shortage of places to explore. Whether you’re hiking around South Platte River Trail, heading toward Red Rocks for the day, or taking a weekend drive into the Rockies, spending time outdoors is one of the best parts of living in Colorado.
Unfortunately, hiking season also brings an increase in skin rashes, allergic reactions, sun-related irritation, and plant exposure injuries. Many hikers expect poison ivy to be the main concern, but Colorado trails can expose you to several other plants and environmental irritants that can leave your skin red, itchy, swollen, or painfully irritated.
At AFC Englewood, CO, we commonly treat patients dealing with hiking-related rashes during the warmer months. Knowing what causes these rashes, how to prevent them, and when to seek medical care can help you enjoy Colorado’s trails with a little more confidence.

Why Hiking in Colorado Can Trigger Skin Irritation
Colorado’s dry climate and higher elevation create unique conditions for outdoor skin irritation. Strong UV exposure, warm temperatures, sweat buildup, and contact with local vegetation can all contribute to rashes after a hike.
Some of the most common causes include:
- Poison ivy exposure
- Contact dermatitis from wild plants
- Heat rash from trapped sweat
- Sunburn or sun poisoning
- Exercise-induced vasculitis (“hiker’s rash”)
- Insect bites and allergic reactions
- Skin irritation from dry mountain air and friction
According to the National Park Service, hikers in Colorado should stay alert for trail vegetation and environmental hazards, especially during peak summer hiking season.
Colorado Plants Besides Poison Ivy That Can Cause Rashes
Most people know to avoid poison ivy, poison oak, and poison sumac, but Colorado hikers encounter several additional plants that can irritate the skin.
Stinging Nettle
Stinging nettle grows near streams, wooded trails, and moist areas throughout Colorado. Tiny hairs on the plant release irritating chemicals when touched, often causing:
- Burning or stinging sensations
- Raised bumps or welts
- Temporary numbness
- Redness and itching
The irritation usually fades within a few hours but can linger longer for people with sensitive skin.
Wild Parsnip
Wild parsnip contains sap that reacts with sunlight and may cause phytophotodermatitis, a painful skin reaction that can resemble a burn.
Symptoms may include:
- Blistering
- Dark skin discoloration
- Painful redness
- Skin sensitivity after sun exposure
Ponderosa Pine and Juniper Irritation
While not poisonous, sap, pollen, and oils from pine and juniper trees can irritate sensitive skin during long hikes or windy conditions.
Ragweed and Sagebrush
These common Colorado plants can trigger allergic skin reactions and worsen seasonal allergy symptoms during late summer and early fall.
How to Prevent Hiking Rashes Before You Hit the Trail
A little preparation can dramatically lower your chances of developing a hiking-related rash.
Before your next outdoor adventure:
- Wear lightweight long sleeves and hiking pants on overgrown trails
- Apply broad-spectrum sunscreen regularly
- Stay hydrated throughout your hike
- Avoid touching unfamiliar plants
- Change sweaty clothes quickly after hiking
- Shower soon after returning home
- Wash backpacks, socks, and pets after trail exposure
- Wear moisture-wicking fabrics to reduce heat rash
If your skin has been exposed to a poisonous plant while hiking, it’s also a good idea to wash your hands in cold, fresh water with a degreasing soap such as Dawn to break down the oils in the plant before they spread.
What To Do at Home if a Rash Develops
Even experienced hikers occasionally develop skin irritation after spending time outdoors. Fortunately, many mild rashes can be treated at home.
If you notice itching or redness after a hike:
- Wash the affected area with cool water and gentle degreasing soap
- Apply cool compresses to reduce inflammation
- Use over-the-counter hydrocortisone cream or calamine lotion
- Avoid scratching the rash
- Wear loose-fitting clothing while the skin heals
- Drink extra water to stay hydrated
For hiker’s rash or exercise-induced vasculitis, elevating your legs and resting indoors often helps improve symptoms within several days.
