Trail is 3.5 miles long from the parking lot to the summit. The trail is almost entirely in the Mount Evans Wilderness. No mountain bikes are allowed in the Wilderness. Stay on the trail to avoid trampling the vegetation. This is a great all day hike in which you will climb two 4ers, Mt. Bierstadt and Mt. Evans. In the process you will also traverse the saw tooth that seperates these two mountains. The hike up Bierstadt itself is faily easy and we even ran into people with their dogs. However, the crossing of the saw tooth will take you on a very intense class 3 scramble and is not dog or little child friendly. In fact, its not friendly for anyone who is not in shape or not able to take on a class 3 scramble. Its a great hike and a fun way to bag two 14ers in one day! Start out early if you plan to do both peaks, especially if you aren't used to the altitude. Wear clothes that will keep you warn during the ascent up Mt. Bierstadt and that will be easy to shed once you reach the peak and sunshine. Also, be prepared for strong winds and colder temps on the way up Bierstadt. I would strongly recommend leather gloves for the crossing of the saw tooth.

Tough trail on Sunday Oct. 16, 2016. It was 40 degrees with 60mph of wind. I had a 30lb pack on my back. It took 4.5 hrs to get to the top in these harsh conditions. 2.5 down. More than half of the people out that day turned around at or before the half way mark. The trail was very steep and had numerous icy and very muddy spots that were very slippery. I recommend ice cleats and also to dress very warm and bring hand warmers and warm wind proof gear, (which thankfully I had) if snow and cold temperatures are present. I braved the weather and made it to the summit. It was a challenge in the weather but well worth the effort! I would do this trail again in nicer conditions but I warn you it is a lot tougher than it's rated for being the so called "easy" 14er. I clocked 4.2 miles from the parking lot to the summit. 8.4 round trip on the GPS. Good times!!

Hiked 10/13/16. Great trail that provides a little challenge if you push yourself. I went on a Thursday and didn't see many people on the trail. Took 3 hours to summit but I was pushing myself and packed a heavy pack with additional weight. Although I didn't do it- for those who want additional challenge - you can cross the sawtooth from the summit over to the Mt Evans summit. **watch every step on the decent! The snow patches get packed down and freeze- very slippery!

Took me and my wife a while to get up but very well worth it.

Oct. 9th - We got an early start: 6:30am & there were about 4-6 other cars in the lot. Feeling a bit under the weather the climb was a little difficult for me. There are a lot of misleading trails going up. Some snowy patches. 3 hours up, freezing cold/windy at the summit. Great views, totally worth it! 2 hours down. Had to be extra careful coming down on the ice/packed snow & also passed 141 people going the earlier the better! Would do again

Be prepared for the weather changes. Even in the end of June, there's still some snow on the trail. I started with a tank top and ended up with a hoodie and a down jacket on at the top. The view was absolutely beautiful and breathtaking. One thing I would have to say is it's kind of hard when you are going down. My knees hurt a bit by keep going down for about 3 hours.

I've hiked this twice, about 3 years apart (almost to the date, by accident haha). It's a great hike, especially for getting your feet wet with summiting 14ers. As with all 14ers, look at the most recent trail reports, check the weather, bring lots of layers/food/water, and starting earlier is always better.

The weather conditions were great today with little wind, mild temperatures and partly cloudy skies. The trail was gorgeous and well laid out but quite challenging for me. Unfortunately, I lost my white gold wedding band in the rocks on the final ascent to the summit and was not able to locate it. If anyone happens to discover it on subsequent hikes, please email me at djgagne at ou dot edu.

Well maintained trail making it easy for hiking. Lots of up hill so it's a lung buster! Lower half has more shrubs while the upper is rocky and open. The wind blows pretty hard as you ascend. Be prepared with warm clothing. Breathtaking views at the top with some great flat rocks for a picnic hidden from the wind in the sun.

Beautiful, well maintained trails. Very cold- my camelback tubing froze, but I was prepared. The wind close to the summit was such that I had trouble standing- was kinda crawling up the scramble. I had to turn back because of this. Lightly packed snow below 13 k and not icy. Gorgeous day and can't wait to try again!!!

Mount Bierstadt was great day hike. It was my first 14er. High traffic trail, but everyone was so friendly and encouraging. Great views once you summit. Very windy, and a bit cool.

This was my first 14er and it was a nice start! We hiked it in the middle of the week so there was not much traffic. The first mile and a half is mostly boardwalks but It gets progressively harder. The top is a scramble, but the cairns give a good idea of the best way up. I would not recommend bringing your dog unless he/she is quite surefooted and can jump up big boulders. There is even a little geocache at the top. This was a very fun and rewarding hike!

There are always a ton of people, so that's just something you have to deal with. It's a gorgeous hike across a valley and up the ridge to the summit where you can see Evans, Grays, and Torrey's. Not too hard for a 14er so a great one if it is your first. Have fun!

This was my first 14er experience and it did not disappoint. The weather today was beautiful. I brought lots of layers and ended up stuffing them in my backpack, which wasn't so fun (7 miles hauling around a bulky/heavy pack is no fun). Started the trail at 7:30 am and summited in 2 hours and 45 mins. I was pleasantly surprised by how few people were out at this time (I'm sure I have Monday to thank for that). There were definitely a lot more people coming up when we were heading down. I would highly recommend this hike for someone's first time conquering a 14er!

This was my very first 14er and I loved it! the views were spectacular and it isn't too far a drive from Denver. The only thing I wasn't a fan of was the amount of other people at this trail. It's very popular!

Terrific hike, started at 2:30 a.m. since we were hoping to do the sawtooth over to Mount Evans. Didn't get to it, to much cloud cover and there was about 3 inches of fresh snow on the summit this morning. No cover the entire trail and muddy at the start.

This us rated as difficult here, or a class 2 14er everywhere else, but I really enjoyed the scramble at the top! It was surprisingly fun, and the fall colors are out in full swing right now on your way down. Only a little ice on the trail, did not need spikes. Went on a Friday morning in early September, left the lot at 7:30 and there were still a few spots left. Would recommend going later in the season like this because there was just the right amount of hikers.

PLEASE pack out what you pack in and stay on the trail. This trail is being restored because so many people go around mud and stuff on the trail, and end up meadow stomping. Also, so much toilet paper just left in the buses.

Hiking on a Wed in September has many advantages. I left the trailhead at 7:00 am. There were only about 7 other people on the trail at that time. I wore 3 layers the whole hike. It was VERY windy the top one third of the hike. Cold. Needed full hat and gloves. It took me about 2.5 hours up and 2:15 down. I used hiking poles coming down. Beautiful day. As I came down crossed paths with approximately 30 other people hiking up.
