  2. Silence is Golden: Move quietly. Loud noises can scare away animals. If you’re hiking in a group, communicate in hushed tones.
  3. Stay on the Trail: While the urge to venture off the beaten path can be strong, it’s essential to stay on designated trails to minimize disturbance to wildlife habitats.
  4. Binoculars and Cameras: Always carry a pair of binoculars and a camera. Binoculars enhance your viewing experience, and a camera helps capture those unexpected moments.
  5. Safety First: While encounters with wildlife can be exhilarating, it’s crucial to maintain a safe distance. Never approach or feed wild animals. If you come across predators like mountain lions or bears, avoid direct eye contact, make yourself appear larger, and back away slowly.
  6. Educate Yourself: Before embarking on a hike, familiarize yourself with the wildlife native to the area. This not only enhances your experience but also ensures that you can identify and appreciate the creatures you come across.
  7. Leave No Trace: Preserve the beauty and sanctity of the forest by adhering to the ‘Leave No Trace’ principles. Carry out whatever you carry in, and avoid leaving food scraps that might attract wildlife.

The Arapaho National Forest, with its rich biodiversity and network of trails, is a paradise for wildlife enthusiasts. Each hike offers a unique opportunity to connect with nature, to witness the raw, untamed beauty of the wild, and to carry back memories that last a lifetime.

As you lace up your hiking boots and set out on these trails, remember that you’re not just a visitor; you’re a custodian of the forest’s timeless legacy.

15 Tips to See Animals While Hiking in Arapaho National Forest

  1. Seasonal Timing: Visit during late spring or early summer. Many animals in Arapaho, like elk and mule deer, are more active during their calving season, which typically falls in these months.
  2. Dawn and Dusk at Echo Lake: The Echo Lake Trail is known for birdwatching. Plan your hike during the early morning or late evening when birds like the Red-tailed Hawk or Bald Eagle are most active.
  3. Niwot Ridge for Larger Mammals: For a chance to spot elk or even the elusive mountain lion, hike the Niwot Ridge Trail, especially around dawn or dusk.
  4. Listen for Pikas: As you traverse areas with rocky terrains, like parts of the Rainbow Lakes Trail, listen for the distinctive calls of pikas, especially during warmer months.
  5. High Altitude Hikes for Bighorns: Trails that ascend to higher altitudes, such as Jones Pass Trail, often have herds of bighorn sheep grazing in alpine meadows.
  6. Stay Overnight: Consider multi-day hikes or camping in designated areas. Animals are often more active during the night, and the serene early mornings can offer excellent viewing opportunities.
  7. Look for Animal Tracks: Familiarize yourself with the tracks of animals native to Arapaho. Fresh tracks can guide you to recent animal activity.
  8. Visit Water Sources: Animals frequent water sources, especially during dryer months. Trails that pass by streams or lakes, like parts of the Vasquez Peak Wilderness, can be hotspots for wildlife.
  9. Be Patient at Clearings: Open areas or clearings, especially in dense forest regions, are often grazing spots for deer and elk. Find a quiet spot, sit down, and wait patiently.
  10. Avoid Peak Human Traffic: Animals tend to shy away during peak hiking hours. Opt for weekdays or off-peak hours to hike popular trails.
  11. Use Local Knowledge: Before setting out, chat with local rangers or visit the Arapaho National Forest’s visitor center. They often have up-to-date information on recent wildlife sightings.
  12. Minimize Noise: While it’s essential to make noise in bear country to avoid startling them, in general areas, move quietly to observe more wildlife.
  13. Look Up: While hiking in forested areas, don’t just focus on the ground. The dense canopies of Arapaho are home to various bird species. Carry a bird guide specific to Colorado to identify them.
  14. Bear Safety: Black bears are residents of Arapaho. While it’s thrilling to spot one, ensure you’re aware of bear safety guidelines. Carry bear spray, especially if venturing into dense, less-traveled areas.
  15. Respect Wildlife: Always view animals from a distance. Approaching or feeding them not only endangers you but can also harm the animals and alter their natural behaviors.

Remember, while the goal is to witness the majestic wildlife of Arapaho National Forest, it’s equally crucial to ensure their safety and well-being. Always prioritize responsible wildlife viewing practices.

Best Time to Visit Arapaho National Forest for Animal Sightings

Arapaho National Forest, a mosaic of pristine landscapes and diverse habitats, is a wildlife enthusiast’s dream. The forest’s inhabitants, from majestic elk to chirping birds, follow the rhythms of the seasons, making certain times of the year particularly rewarding for sightings.

While each season has its charm, based on our extensive experiences and observations, we highly recommend visiting during the fall. Here’s why:

Overview of Seasonal Animal Activities:

Spring (April to June): Spring heralds the forest’s awakening. As the snow retreats, elk and mule deer begin their calving season. Birds return from their winter migrations, filling the air with melodic songs. While spring is vibrant, the unpredictable weather can sometimes be a deterrent.

Summer (July to September): Summer in Arapaho is a bustling time. Pikas, snowshoe hares, and squirrels are especially active. Birds, from Lark Buntings to Red-tailed Hawks, are in abundance. However, the trails can get crowded, and the animals, wary of human presence, might be less visible during peak hours.

Fall (October to November): Fall is a magical time in Arapaho. The forest is a canvas of golds and reds, and the cooler temperatures make hiking a pleasure. This is the period of the elk rut, where male elks engage in powerful displays of dominance. The crisp air and reduced foot traffic mean animals are more active during the day, increasing the chances of sightings.

Winter (December to March): Winter transforms Arapaho into a serene wonderland. While many animals hibernate or migrate, you can still spot snowshoe hares and resilient bighorn sheep. Birds of prey, like Bald Eagles, stand out against the snowy backdrop.

Recommendations Based on Personal Experiences:

Why Fall Stands Out: Our treks during fall, especially on the Rainbow Lakes Trail, have been nothing short of spectacular. The forest, with its vibrant foliage, creates a backdrop that accentuates the beauty of its inhabitants.


The reduced human activity means animals like bobcats, black bears, and mule deer are more visible and less skittish. The sounds of the forest, particularly the haunting bugle of the male elk, add an auditory depth to the experience.

Insights on Migration Patterns and Breeding Seasons:

Bird enthusiasts should note that many avian species in Arapaho are migratory. While spring sees their return, fall is when they prepare for their onward journey, making it a bustling time for bird activity.

Elk, the forest’s crown jewels, are particularly active during fall. The rutting season, with its displays of strength and dominance, is a must-witness event. The cooler temperatures also mean that animals are active for longer periods during the day, increasing the chances of sightings.

While Arapaho National Forest promises a rich wildlife experience throughout the year, fall stands out as the prime time for animal sightings.

The combination of favorable weather, reduced crowds, and heightened animal activity makes it our top recommendation. Whether you’re an avid wildlife photographer or someone seeking a serene communion with nature, a fall visit to Arapaho will undoubtedly be a memorable one.


Arapaho National Forest, with its vast landscapes, diverse ecosystems, and rich tapestry of wildlife, stands as a testament to nature’s grandeur. Each trail, wilderness area, and season offers a unique window into the forest’s soul, revealing stories of survival, beauty, and coexistence.

While every visit promises a blend of adventure and serenity, it’s the informed choices, based on understanding the forest’s rhythms and respecting its inhabitants, that make the experience truly enriching.

Whether you’re tracing the footsteps of elusive mountain lions, witnessing the powerful elk rut, or simply soaking in the forest’s tranquility, Arapaho beckons with experiences that linger long after the journey ends.

As stewards of nature, it’s our privilege to explore, appreciate, and protect this magnificent realm, ensuring that its stories continue to inspire generations to come.
