Really cool trail! Especially if you’re looking for a hike that isn’t going to take all day. The fire tower was amazing, the views were insane! My boyfriend discovered that he was terrified of heights but definitely worth the climb! Haha.

beautiful, moderate hike, very crowded on the weekends. recommend arriving at trailhead before 730am. diamond lake has plenty of space for the masses but is busy by 930am. recommended!

Attempted this hike today and saw 2 Rattlesnakes on the trail within the first .5 miles. I was alone and decided not to risk it but will re-attempt in cooler temps with a buddy. Trail looks very nice but minimal shade.

As with many others, this was my first "fourteener" and it was a blast. Couldn't of asked for better weather. Stayed in Georgetown, and got to the Guanella pass parking lot at approximately 0600. Yes, it was already full, however the summit overlook parking lot still had spaces left.I'm a flatlander from northeast Ks. but went prepared. Took my time, with frequent breaks, especially the higher I got. The scramble to the top was probably the toughest part, but by that point you've gone to far to not do it. While many folks, myself included, do Mount Bierstadt because their research reports it as being the easiest fourteener. Be forewarned - if you are a flatlander, even one who is in decent shape, there is nothing easy about trying to breathe at altitude.However do not let that dissuade you from doing this hike, as I can assure you that you will not be alone. Start to finish approximately 6 hours, half hour to 45 minutes on the summit.

Quintessential Boulder hike. Went clockwise today - I prefer to tackle the big “steps” on the ascent and come down through the valley. Always nice to have bathrooms (across the street from the trailhead.) Friendly faces and interesting terrain. A perennial favorite.

Nice trail with a variety of terrain. This trail may be considered hard for those who do not hike frequently... some narrow, rocky areas with over 1000 ft of elevation change. The river was a nice spot to stop for a rest half way through the hike.

Great hike! Definitely not too difficult... fairly trafficked on the weekend as of you approach the Lake. Lots of fun waterfalls and little features along the way.... If you’re doing this on a weekend definitely make it to the trail head by 7-7:15AM or you’ll be in a jam to find parking! We made it at 8 and parked about a half mile down!

Great hike. A little crowded on weekends but worth it.

Great trail. Lots of climbing on the way up, but it’s all worth it for the views at the top. Go early to avoid the crowds – it was already pretty busy at 7am and people were lined up inching along the narrow paths on on the way down. Free parking is available about 10 blocks away.

This hike is great for a very easy hike with some awesome views. If you enter from Eldorado Springs you'll have to pay $8 to park your car, but you really see where that money goes while walk the well manicured trail with retaining walls on the side. If you park at the other end of the trail it's free (considered Boulder Open Space). The first half of the hike is very scenic, while the rest is pretty open and not as many views. I would suggest branching off to Spring Brook North Trail or Rattlesnake Gultch.

Vraiment beau paysage !!

Beautiful trail. Definitely arrive by 7:30 am to avoid heavy traffic. If you are not an early riser and always lucky, arrive around 10 am to take the early birds' spots.

Great morning hike! Took me 2 hours with a 15 min stop at peak.

A perfect hike for a time period of about 2 hours! Amazing views at the top! Have hiked this trail multiple times and it never disappoints!

A nice workout with a strong hill qt the end. - beautiful - the river was great for my dog too :)

Great 14er for first timers and out of staters.

Beautiful scenery but there are better ones than this lake.

I liked that this trail had variety of sceneries. Many shaded area as well as some meadows and rocky terrains. Great for dogs since there is a creek running by, and the lakes to get to. Wild flowers are beautiful in August. I saw a coyote (I think) and moose!

Certainly challenging, but nothing to lose sleep over. Expect to wait in line if you’re hoping to get decent pictures at the top.

This hike offered a quick escape from Denver heat today, but not much escape from crowds. We enjoyed the trail, but it was very crowded and of course, there was a lot of dog poop along the trail and two dogs off leash, despite someone asking the owner to leash them. I think this hike would be much better during the week; it was just too busy on a weekend.

Quick and fun. Did it with my nephews - both 7 years old. They enjoyed the Tower and talking with the Ranger at the top. The views are fantastic.

"Stairmaster Sanitas" is a great place to get a very real workout in. We are in decent shape and climbed up Sanitas and went back around the valley loop trail within 2.5 hours. I would categorize this as "moderate to hard" given a few of the rocks you have to scramble over and how steep it is. While you can carry a child on a backpack up an down, it's not the greatest one to choose for that since you might have to shuffle a bit over rocks, etc.

Great scenic trail. Seems crowded on weekends.

Loved the hike there. Got to the trailhead at 5:45 PM for a sunset hike and finished the hike at 8:20.. about 2.5 hours of hiking and gaping at how beautiful Golden/Colorado is at the golden hour and at sundown.. the trailhead is wayyyy less trafficked at the time we went. Had my dog on a leash all the time because of the rattlesnakes but seemed to be ok!

Great hike. Decently steep towards the top before the lake but gem lake is beautiful. Went further to balanced rock which was an 8 mile round trip and had some good views along the way. Would hike again!!

It's worth the uphill grade to see Emerald Lake. Very pretty and attainable.

Scenic and forested. The last 3/4 of the hike got hard and had me wondering if I was ever going to make it, but it was worth the effort to get to beautiful mountain lakes.
