If you’ve been to Lake Haiyaha before summer 2022, you need to go back! The color of the lake is completely different and no one knows how long it will remain the magical milky blue-green turquoise color. The trail to Lake Haiyaha is typically covered in snow through May and possibly early June, but it’s melted by July-Sept and would be a great time to visit if you can snag a permit!

2025 Lake Haiyaha conditions update
I recently went back to Lake Haiyaha on July 9, 2025 to see what the color looks like since the rockfall. The glacial silt is holding strong and the color is more turquoise now than the milky green color from right after the incident. It’s 100% worth visiting right now! Keep reading for full details on how to hike Lake Haiyaha.
Do you need a pass for Lake Haiyaha?
Rocky Mountain National Park requires timed entry reservations from May 23 – Oct 19, 2025 between the hours of 5 am to 6 pm — make sure you select the option with Bear Lake Corridor Road.
The reservation allows a two-hour block for entry and you can stay as late as you’d like in the day. 40% of reservations are released the night before your selected day at 7 pm MT so if you didn’t book an advance reservation, there’s still a chance!
Lake Haiyaha is just one of the many alpine lake hikes near Denver, CO but it should be at the top of your summer bucket list!
Why is Lake Haiyaha so blue now? How is it a different color than before?
A rockfall event on the South Slope of Hallet Peak on June 28, 2022 caused rocks to slide into Upper Chaos Canyon with Lake Haiyaha just below it. This event transported a lot of glacial silt into Lake Haiyaha which creates that milky turquoise blue color

How long is the Lake Haiyaha hike?
According to the NPS site, it’s 4.2 miles out and back; however, my GPS tracker marked it as 2.74 miles round trip, and the Caltopo maps tracked it at 3.2 miles. Regardless, it is a relatively short hike that can be done in less than three hours total but leave some time to enjoy the lake.
How hard is the hike to Lake Haiyaha?
The hike is short and easy for all levels. I visited Rocky Mountain National Park during the busy season when reservations are required from May through October. If you’re planning a trip to visit Rocky Mountain National Park in the summer, this next bit may help.
Lake Haiyaha Trailhead
It gets very crowded in the summer months and there is a shuttle system in place for overflow parking to easily access the Bear Lake Trailhead – the shuttle comes often and the ride is short, only about 2-3 stops.

Lake Haiyaha Trip Report
We started our hike at 10:26 am and within 10 mins, we passed Nymph Lake which was incredible to see with lilypad-like leaves floating along the edge of the lake. The trail goes through the forest and along the edge of the mountains so there is plenty of shade and although it is only <2 miles one way on a very crowded trail, the hike still provides a feeling of wandering in the wilderness.
Once you reach Lake Haiyaha, there are a lot of large boulders you can sit on for a snack to enjoy the view of Hallet Peak. Since it is a popular trail, you may want to get away from the crowds but still be by the water – walk around to the east end of the lake (your right side when staring at Hallet Peak) and cross some logs and rocks at the end of the lake to find some solitude.
With very little elevation gain overall and epic views of Rocky Mountain National Park along the way, this hike is perfect for the whole family!
This trail also splits off to Dream Lake and Emerald Lake which are only an extra 0.7 miles one way. Dream Lake is literally just around the corner from the trail junction so check it out on your visit!
