The loop begins at the foot of the Maroon Bells in the Elk Mountains, just outside Aspen. It spans 28 miles, includes 7,000 feet of vertical gain, and crosses four mountain passes above 12,400 feet.
Over a recent long weekend a friend and I took on the loop. What seemed like thousands of others had the same idea. We arrived at the trailhead just before 6am, luckily out to grab the last spot in the lower lot. Car trunks opened as we headed to Maroon Lake to enjoy sunrise, revealing hikers who'd spent the night to reserve their own spot. That's Colorado for you.
We decided to travel counter-clockwise, which fewer people do because it's supposedly harder. While the jury’s still out on the complete truth of that, a tougher first day was well worth it to avoid some of the crowds.
Ten miles and 3,000 vertical feet later we arrived at Snowmass Lake. I could've ended the trip there completely satisfied.
"I was constantly reminded that we don't conquer mountains, they let us exist in their world."
Over the next four days I was constantly reminded that we don't conquer mountains, they let us exist in their world. We enjoyed perfect weather, and every day a new pass greeted us with another spectacular view completely different than the last. The usual attention tung of war between social media, TV, and advertising was replaced by towering peaks, pristine alpine lakes, and fields of wildflowers.
We met an older man from Australia who joked about rules against running on the trail when we passed him. A lady from New Hampshire said the exposure in the mountains here makes her cry. Her husband mouthed "thank you" when we told her the rest of the way was well protected. Our final day was spent with a crew of guys from Salt Lake swapping stories and quotes from Dumb and Dumber.
It wasn't a quiet trip by any means, but meeting people from all over the world is a part of the Four Pass experience. It reminded us how special this place is, how lucky we are to live in Colorado, and how many experiences are better shared.

10 Do's and Don'ts for Backpacking Aspen’s Four Pass Loop
DO go when the wildflowers are in bloom. Usually before September.
DO take four days to finish. It's worth taking the time to soak it all in.
DON’T forget rain gear. Especially in early season there's a high chance you'll get stormed on at least once.
DON’T be selfish. With so many people on this trail, you'll witness a lot of disrespect for the rules. Read the regulations and leave no trace. Please.
DO catch a sunrise at Maroon Lake, Crater Lake, and Snowmass Lake.
DO bring a bandana or wide brim hat. You'll spend a lot of time above tree line with no shade. Pro tip: soak your bandana in a stream and then put it on. Life-changing.
DO share the adventure. People come from all over the world to hike here. Swap stories and get to know those on the journey with you.
DON’T forget trekking poles. They help immensely with all the steep uphill and downhill on this route.
DON’T go the typical way (clockwise) if it's busy. The first day is tougher, but you'll have more solitude.
DO drive Independence Pass on your way in or out. The views are simply spectacular.
