Reserve campsites/lodging
If you are going to be staying at a resort or hotel, then you will need to reserve those accommodations early. But, if you are CAMPING (either tent camping, or Sprinter Van/RV/Camper camping), you will NEED to reserve these spots super early. They go like hotcakes. I’m not really sure what that means, either. But, let’s just agree to agree that they sell out quickly. Make sure to check out how we tell you all the amazing apps you can use to find campgrounds!

Prepping Gear
Depending on where you are going, and when, and who is going with you, you will need to pack certain gear. Take time before to find, purchase, and pack the gear you need. Consider our 17 things you need to pack, but didn’t think of, as well as our list of essentials for a day hike.

Gear is really important, and give yourself the time to think, research, and plan for the things that you will most need and want during your vacation. Frankly, I even make lists for food and clothing. (But like I said, I’m a planner, people.)

Step by Step DETAILED Directions (TWO OPTIONS!)
Your days of feeling “Map-ically Challenged” are over! (Trademark on that pending!) These maps (both simple and detailed), along with exceptionally clear instructions, are all provided for you in this post!
3D Map
Please note: The 3D maps in this post, and below are NOT FACING NORTH (on purpose!). Repeat: These maps do NOT face North. These maps are shown specifically for those of us who are “map-ically challenged” and need to visually see which way we are hiking. Please refer to the compass at the bottom right of the map below to show where NORTH actually is!
CLICK ON THE MAP BELOW, OR CLICK HERE, AND YOU WILL LINK TO THIS EXACT GOOGLE MAP. You can zoom in on it and take as many screenshots as you would like! If you bring up the map in Google, if you use your mouse and hit CONTROL, then you can MOVE the map to the direction in which you are ACTUALLY HEADED!!!! (Amazing!)
When you click on this, and open the map, you can then click on the link below the blue box on the left and have these directions sent DIRECTLY TO YOUR PHONE!
You can then screenshot those images, so that you can see these directions, and maps, even if you do not have wi-fi as you are hiking!
Finally – look look LOOK! AT THE BOTTOM RIGHT of the map. See that little yellow guy? Click on him when you open up the map on your phone. You can see ACTUAL PICTURES on the blue dots that people have taken. This is a GREAT resource to have. If you look at your map before you go, you can screenshot what the intersections in the trail look like to help you navigate your way, and not get lost!
First Option – From Glacier Gorge Trailhead
- Start early, especially if you are traveling to Mills Lake from Denver, grab your coffee at Kind Coffee in Estes Park, and head out!
- Travel on US 36 highway to Bear Lake Road.
- Travel to the Glacier Gorge Trailhead (Travel 8 miles on Bear Lake Road from US 36). Park in the parking lot. Jump out of your car, stretch (always stretch first haha!) and check the signs. You really should be able to only hike one way, and the signs are clearly marked.
- When you get to the fork in the road, go LEFT towards Alberta Falls. You will be heading southeast at this point, and there should also be signs. Just stay on this trail. Don’t veer off of it (for example, don’t take another left onto Prospect Canyon Trail.) After some time you will see the waterfalls! Enjoy! But this isn’t your final destination! You have much further to go!
- Keep going towards Mills Lake. There should really only be one major trail to go on from Alberta Falls. So take that one, obviously! This will have you traveling for the most part in a twisty, but southerly direction.
- Don’t take the left towards North Longs Peak Trail. Keep going on the Loch Vale Trail.
- This is SUPER IMPORTANT – we got lost going to Mills Lake because we weren’t on point really looking at the signs!
- Then get excited because you are about to take a RIGHT onto Black Lake Trail. Keep going in a south-y kind of direction until you get to it!
- Side note: If you want (and if you have the energy) you can jump back on the trail headed back to your car, but instead of going home and resting with a nice glass of wine, take a LEFT! Don’t take the right on the trail towards Lake Haiyaha or Dream Lake. Just keep going on Loch Vale Trail.
- Then you will see it!!!! The Loch! You will be adding about 1.5 to 2 hours to your trip but it will be worth it and you are in the area – but it’s up to you!
Second Option – Bear Lake Trailhead

Bear Lake Trailhead Map
- The Glacier Gorge Trailhead parking lot can get full quickly. A second option to get to Mills Lake is the Bear Lake Trailhead a bit further up the road (about a mile) on twisty, turn-y Bear Lake Road, instead of the Glacier Gorge Trailhead. The Bear Lake trailhead has a larger parking lot. Again, park in the parking lot and use that restroom if you need to!
- When you get to the actual trailhead, you will see the huge sign for the Bear Lake Hike to your right. Instead, walk a bit to the LEFT, and then when you get to another fork in the road, go LEFT AGAIN. The signs are clearly marked.
- At this point you will walk straight (which will be southeast) all the way!
- Don’t turn right at Dream-Emerald Lakes Trail, unless you want to go to Nymph Lake or beyond.
- Don’t turn right to go to the Glacier Gorge Trailhead (you didn’t park there!) or right onto Prospect Canyon Trail. Just keep going straight, baby! The falls are gorgeous! They are gorgeous! Then continue on to Mills Lake following the directions above. This will add about a mile each way total, so definitely take that into account!

Final Thoughts on Mills Lake Hike
Mills Lake is an incredibly popular hike, and the lake itself is right under the towering and majestic Longs Peak.
Mills Lake is named after Enos Mills, who is really known as the father of RMNP. He wrote many books and really lobbied hard to make the area a national park. The park was officially established in 1915.
This is a moderate hike, but with this guide you will be prepared! You will definitely get your work out, but not to the point of being needed to be airlifted out due to exhaustion. It’s a good five hours of work, and if you add it some time at Alberta Falls, or head back to Bear Lake, it definitely will make a whole day of it. The stunning views will be worth it though, and you will keep a memory of a lifetime.
