The Hike to Twin Sisters Peak

Location: Just outside the town of Estes Park, Colorado, in Rocky Mountain National Park.
Distance: Approximately 7.5 miles round trip.
Elevation Gain: Around 2,500 feet, with the trail reaching a summit elevation of 11,428 feet.
Difficulty: Moderately strenuous due to the elevation gain and high altitude, but it’s considered manageable for most intermediate hikers.

The hike starts at the Twin Sisters Trailhead, located just south of Lily Lake. The trail is well-marked and winds through a variety of terrain. You’ll pass through dense pine forests, which gradually open up to reveal incredible views of Longs Peak, Meeker Peak, and the Continental Divide.

As you climb higher, the landscape becomes more rugged and rocky. After about 3 miles, you’ll emerge from the tree line and reach a saddle between the Twin Sisters Peaks. From here, the final push to the summit is more exposed but offers breathtaking panoramic views, including Estes Park, Rocky Mountain National Park, and even the Great Plains to the east on a clear day.

Twin Sisters Peak: Highlights

Stunning Summit Views: Once at the top, you’ll enjoy sweeping 360-degree vistas of the surrounding mountains, particularly Longs Peak and Mount Meeker.
Wildlife Spotting: It’s not uncommon to spot wildlife like elk, mule deer, and even bighorn sheep along the trail, especially in the lower forested areas.
Alpine Terrain: After emerging from the trees, the trail takes you into a more alpine, rocky environment, offering a true mountain hiking experience.

Know Before You Go: Hiking Twin Sisters Peak

Permits: No permits are required to hike Twin Sisters Peak, but if you’re entering the park from Estes Park, you will need a timed Entry Permit or a National Parks Pass during peak season.
Weather: Be mindful of weather conditions, as thunderstorms are common in the afternoons, and temperatures can drop significantly at higher elevations.
Trail Conditions: In winter and spring, parts of the trail can be snow-covered or icy, so microspikes or snowshoes may be necessary.

What to Bring: Hiking Twin Sisters Peak

When hiking Twin Sisters Peak in Rocky Mountain National Park, it’s important to come prepared, as the trail is moderately strenuous, and weather conditions can change quickly at higher elevations. Here’s a comprehensive list of essentials and recommended gear to bring:

Daypack: A comfortable, durable backpack with enough space for water, snacks, layers, and other essentials. Here is the super reasonably priced one I use from REI!

Hiking Boots: Sturdy, waterproof hiking boots with good ankle support. The trail is rocky and uneven in places, so you’ll want footwear with excellent traction. Below are my tried and true hiking boots that I’ve used for years.

Layers of Clothing:
- Base Layer: Moisture-wicking, breathable fabric like merino wool or synthetic materials.
- Mid-Layer: An insulating layer, such as a fleece or lightweight puffy jacket, to keep you warm as you gain elevation.
- Outer Layer: A windproof and waterproof jacket for sudden weather changes, especially at the exposed summit.

Hat and Gloves: Even in summer, it can be chilly and windy at the top. I use the REI gloves I have linked below as well as a few of the beanies I own. The North Face and Carhartt ones are my go-tos!

Water: Bring plenty of water (at least 2-3 liters), as the elevation gain and dry mountain air can lead to dehydration quickly. Consider a hydration bladder for easy access. This hydration bladder from amazon is perfectly compatible with my REI daypack!

Snacks/Food: Pack high-energy snacks such as trail mix, protein bars, dried fruit, or sandwiches to refuel along the way.
Trekking Poles: Useful for stability on steep, rocky sections, particularly during the descent. I got the ones below from amazon for next to nothing and they get the job done!

Sunscreen & Sunglasses: The sun at higher altitudes is much stronger, so protect your skin and eyes even on cloudy days.

Map or GPS: Although the trail is well-marked, it’s always a good idea to carry a trail map or have a GPS device for navigation, especially in poor visibility.
Headlamp: If you start early or expect to hike in low light, a headlamp is handy. I never leave for a hike without mine!

Microspikes or Traction Devices: If you’re hiking in late spring, fall, or winter, snow and ice may still cover parts of the trail. Traction devices provide stability in icy conditions. These crampons I ordered from amazon are nice because they aren’t too heavy and provide good traction.

First Aid Kit: A small, lightweight kit with essentials like bandages, blister care, pain relievers, and any personal medications.
Emergency Shelter: Consider a small, lightweight emergency blanket or bivy for added safety in case of unexpected weather.
Phone and Portable Charger: Keep your phone for navigation, photos, and emergencies, but bring a portable charger since batteries tend to drain faster in cold weather.
Permit/National Park Pass: Make sure you have your National Park Pass or Timed Entry Permit if visiting during peak season, especially if entering from the Estes Park side.
Bear Spray: Though sightings are rare in this area, carrying bear spray is a good precaution in case of an encounter with wildlife.
Cold Weather: Extra layers, a thermal hat, and a buff or neck gaiter.
Rainy Conditions: A rain cover for your backpack and waterproof pants in case of a sudden downpour.

Final Tips:

Start Early: Afternoon thunderstorms are common in the mountains, so it’s best to start your hike early to avoid weather risks. It is worth noting that I did this hike for sunset and stargazing. Luckily I only dealt with a brief mild drizzle.
Check the Weather: Always check the forecast before heading out and be prepared to turn around if the weather worsens.
Pace Yourself: The elevation can be tough, so take breaks, hydrate often, and don’t rush the ascent (I did experience some altitude sickness symptoms).

Having the right gear and preparation will make your hike more enjoyable and safer, allowing you to fully appreciate the incredible views and experience on Twin Sisters Peak!
