Glacier Gorge, Lake Haiyaha and Emerald Lake Loop

The Glacier Gorge, Lake Haiyaha and Emerald Lake Loop typically starts from the Bear Lake Trailhead in Rocky Mountain National Park. Parking at Bear Lake can be very challenging, especially during peak season. It's highly recommended to arrive early in the morning or utilize the park's free shuttle bus system. You can find more information on shuttle services and parking on the NPS website.

Yes, Rocky Mountain National Park requires a timed entry permit reservation to access the Bear Lake Road Corridor, where this trailhead is located, during peak seasons (typically May through October). You will also need a park entrance pass. Check the Recreation.gov website for current requirements and to make reservations.

This loop is generally rated as moderate. While some initial sections are relatively easy, the cumulative distance, elevation gain, and rocky terrain, especially around Lake Haiyaha, make it more challenging than a simple stroll. It can be suitable for active families with older children who are accustomed to hiking, but younger children or absolute beginners might find it strenuous due to the length and varied terrain.

The terrain is quite varied. You'll find relatively flat, well-marked paths, some even paved, near the start. As you progress, the trail becomes more rocky and rugged, with switchbacks and gradual inclines. The approach to Lake Haiyaha involves navigating large boulders. Expect a mix of wide, maintained paths and more challenging, less manicured sections.

This route is packed with stunning alpine scenery. You'll encounter several beautiful lakes, including Nymph Lake (known for lily pads), Dream Lake, Emerald Lake, and the uniquely turquoise Lake Haiyaha. You'll also pass by Alberta Falls and enjoy spectacular mountain views, including the dramatic cliffs of Hallett Peak.

Lake Haiyaha's distinctive blue-green, almost turquoise, hue is a result of a 2022 rockslide. This event ground rocks into fine silt and clay, which now reflect light in a glacial blue shade, making it a particularly captivating sight.

The best time to hike is typically during the summer and early fall (June through September) when the trails are mostly clear of snow and the weather is generally pleasant. Fall offers beautiful autumn colors. However, this is also the busiest time, so expect crowds and plan for timed entry permits. Winter hiking is possible but requires proper gear, experience with snow and ice, and awareness of avalanche conditions.

No, dogs are generally not allowed on hiking trails in Rocky Mountain National Park, including this loop. Pets are permitted only in developed areas, on roads, in campgrounds, and in parking lots. Service animals are an exception.

Yes, the trail system in this area is highly interconnected. This route utilizes sections of the Glacier Gorge Trail, Emerald Lake Trail, and Lake Haiyaha Trail. It also briefly touches the Bear Lake Trail. You can extend your hike to other destinations like Mills Lake or The Loch if you're looking for a longer adventure.

Given the moderate difficulty and alpine environment, you should bring plenty of water, snacks, layers of clothing (weather can change quickly), rain gear, sunscreen, a hat, and sturdy hiking boots. Trekking poles can be helpful for rocky sections and descents. Always carry a map and compass or a GPS device, and inform someone of your hiking plans.

The Bear Lake Trailhead area has restrooms. For more extensive amenities like cafes, restaurants, and accommodation, you'll need to visit the nearby town of Estes Park, which is the main gateway community for Rocky Mountain National Park.
