Trailhead & Parking: Mills Lake Rocky Mountain National Park
The trailhead to reach Mills Lake, located at either Glacier Gorge or Bear Lake, is also the starting point for your stunning 5.6-mile out-and-back hike.
This side of the park is much easier to access from Estes Park than Grand Lake because of the distance.
Parking can be found near both trailheads, but keep in mind that lots tend to fill up quickly during peak times and on weekends so plan accordingly.
Once you’ve parked your car, the adventure begins! Along with the breathtaking views, spectacular waterfalls, and crystal-clear lakes, the hike leads to a beautiful, serene lake destination.
Glacier Gorge Trailhead
The Glacier Gorge Trailhead is the perfect starting point for your Mills Lake adventure. The 5.6-mile hike offers a plethora of stunning views and is ideal for hikers of many skill levels. The elevation gain is also a little bit less from this trailhead than from Bear Lake trailhead.
The parking lot at the Glacier Gorge Trailhead is definitely small. It often fills up by 5 am on summer weekends. We got the last parking spot on a Sunday in late July, and we arrived around 4:45 am!
From the trailhead, the route is extremely well marked heading past Alberta Falls to the junction where you will decide to either head to Mills Lake or the Loch and Sky Pond.
Bear Lake Trailhead
The Bear Lake Trailhead is the perfect alternative starting point for your Mills Lake adventure. This route only adds two-tenths of a mile, to end in a 5.8-mile hike.
At 800 feet of elevation gain, it’s just a little more than the route from Glacier Gorge, but going at your own pace makes this hike very doable.
From the trailhead, you can follow signs to Alberta Falls and onward to the Mills Junction, where you’ll take the trail to the left.
After passing through some thick forests and past rocky creeks, you’ll reach the beautiful, crystal-clear Mills Lake.

Alberta Falls at 0.8 miles
Alberta Falls is one of the first must-see sights you’ll come across on your journey to Mills Lake in Rocky Mountain National Park. Located just 0.8 miles from the Glacier Gorge Trailhead, this gorgeous 25-foot waterfall leaps and crashes into boulders below, creating a magical setting for hikers and photographers alike.
During autumn, glowing aspens line the trail and creek, making Alberta Falls even more breathtaking during this time of year. Make sure to bring your camera along so you can capture the sights!
Along with its scenic beauty, Alberta Falls also has some history behind it—the falls were named after Abner Sprague’s wife, an early local resident.
This is the first of the beautiful sites along this trail, and it does get busy during the day. We’d recommend setting out early or waiting until evening to enjoy Alberta Falls.

Mills Lake at 2.8 miles
You’ll reach Mills Lake 2.8 miles from the Glacier Gorge Trail. It is a sight you don’t want to miss on your journey through Rocky Mountain National Park!
This stunning lake provides visitors with peaceful and picturesque views. As you walk the trail, look out for the log bridges that cross Glacier Creek and rocky overlooks with sweeping vistas of Longs Peak and tiny alpine lakes in the distance.
When you arrive at Mills Lake, be sure to take in its majestic beauty—the lake’s long shoreline is dotted with flat rocks that seem to float above the water. Pack a picnic lunch (or breakfast, if you started early) and find a spot along the shore or on one of these flat rocks; enjoy a bite to eat while taking in the breathtaking scenery!
As if that weren’t enough, Mills Lake was even featured on Colorado’s state quarter – how cool is that?
The trail to Mills Lake continues along the shore on the left side of the lake for a stunning stretch of views.

Jewel Lake at 3.2 miles
If you haven’t seen enough stunning scenery at Mills Lake, Jewel Lake at 3.2 miles is a stunning gem in Rocky Mountain National Park! Just a hop and a skip from Mills Lake, Jewel Lake is the perfect place to continue exploring.
The lake’s crystal-clear waters are surrounded by lush greenery and more towering peaks – what more could you ask for? If you didn’t have your packed lunch at Mills Lake, find a spot along this shoreline where you can admire the breathtaking views while enjoying a bite to eat.
Want to Go Even Further?
Ready to explore even more of Rocky Mountain National Park? If so, the trail from Mills Lake continues for nearly 2 more miles to Ribbon Falls and Black Lake. Black Lake is 5.0 miles from the Glacier Gorge Trailhead.
Alternatively, you can start tracking back from Mills Lake, and at the trail junction, decide to head up to the Loch and even Sky Pond. This would be a difficult hike with a lot of elevation gain. It’s not for the faint of heart.
You could also head over to Lake Haiyaha for an easier route and to create part of a loop. It’s another stunning alpine lake in Rocky Mountain National Park, and one you should certainly visit at some point during your visit to the park.
Insider Hints for Mills Lake
If you’re planning a visit to Mills Lake, there are a few insider hints that can help make your trip even more enjoyable. Firstly, be sure to bring plenty of water and snacks with you – there’s nothing worse than being unprepared on the trail!
Secondly, make sure you get an early start; not only will it be cooler in the morning, but the views will be much better before the crowds arrive.
