Rangers recommmended that I did not go up the royal arch without micro spikes! Flat irons loop was icy and snowy as it is!

Icy and snowy on trails! Need micro spikes or at the very least hiking shoes!

Hiked 1/12/2019. Lots of snow, microspikes are helpful. Trail is easy to find. Started at 8:30am, only passed a few people coming up, but trail was busy on our descent.

Great hike and definitely doable and safe for children. I did see the same pit bull the lady below complained about today. It was super friendly and gentle. Unlike her I didn’t see a single pile of poop so not sure if she was looking in the trash or what lol.

Extremely unsafe trail to bring younger children due to lack of enforcement of off leash dog rules. There are literally hundreds of piles of dog excrement within a few short miles.
I can no longer bring my nephew here after we were rushed by an off leash pit bull. Of course the owner thought it was funny. Dog owners in Boulder County are the most entitled and ignorant bunch of people you will ever encounter.

Love this trail. Great length and amazing views. Fenced dog park perfect for wearing out your pup at the end of the trail. Typically do this trail/visit the dog park 1-2 a week.

a challenging hike especially if you’re not used to the elevation. Incline right away and pretty much the whole time, but definitely worth it.

Definetly the hardest hike I’ve been on, bring lots of water and a small snack. If you’re from the Midwest like myself be prepared for the elevation difference, lots of yawns.

We saw 20-30 other groups out on this trail during our 3 hour hike today. Gorgeous views. No snow on the trail, but icy in spots as was mentioned a few days ago.

I hiked this with a group in the fall. Outstanding hike and view at the arch. Hoping to trail run up to the "false summit" in the near future.

Not bad for a quick hike close to the city. You're close to roads and can hear traffic through a good part of it.

Nice short hike, rather steep, cool arch. Currently icy in spots, microspikes very helpful.

Hiked to Lake Dorothy up the Arapahoe pass on Sept 17, 2018. A beautiful day, we arrived at the trail head at 8:30 AM and were able to find a legal parking space just down the hill from the camping area. We only saw 5 other hikers the entire trip; one woman coming down, two college men who passed us on the way up and three people going up on our way down.
Very windy at the lake, The "shelter" at the the lake is little more than an organized pile of rocks that is too short to protect you from the wind. The Arapahoe trail was protected from the wind, and the sunny south exposure was very pleasant. Completed the 7.6 mile round trip in a little less than 4 hours with a lunch break at the lake.

Absolutely loved this trail! It was difficult and beautiful with an amazing arch worth hiking to. We hiked in Arches NP previously and this arch rivals many there, in fact, we were able to get directly under this one and were impressed with its size. The trail was well marked, offered varied terrain, and excellent views. The elevation, icy surfaces, steep inclines, and rock scrambles provided a nice challenge for us, but may make it challenging for some. Many parts of the trail had a thin layer of snow over solid ice, so consider wearing shoes with good traction.

Hiked this trail on 12/30, west side up and east side down. The west side is steep but beautiful, with no ice, and the east side was also scenic with only a couple patches of ice. A great afternoon hike!

Went up from the east to west side - wouldn’t do that again! Decided to do this to get the “ice” out of the way.. yes there was some black ice, but just be aware of the ground when on the top part of the east side. The west side has stairs and I prefer going up stairs than down. This hike was about two hours to go up, enjoy the view, and return to the car with my dog. This hike has a steady incline! Be ready!

I would highly recommend wearing spikes. It was extremely icy- especially closer to the arch. There were point I was crawling on all fours and had to slide down some parts on my butt because it was so icy. Beautiful views though!

Great workout, nice views, and not far from Denver. Would happily do this hike again anytime I’m looking for something short.

Fun to get there! Lots of cool places to climb off trail and great views. Went in December- be prepared for cold weather and ice. Take extra traction if possible to make it easier, not impossible without though.

Great trail & great views. The flat irons are massive and amazing to see!

My partner and I hiked Royal Arch Dec 26th. We left the pup at home, and I’m glad we did because some parts were icy and a little bit more difficult to traverse. I was surprised to see so many folks of all ages on the trail despite being the day after the holiday and how slippery some of the inclines were. It took slightly longer than I had expected but not too bad. I’m glad the weather held off until after we finished though, because I definitely did not look at the forecast. I would recommend making sure it isn’t going to snow/rain for about three hours before embarking.

Overall, the views were great and the arch is bigger than I expected based on the photo. Glad I brought a full bottle of water and let my small pup at home.

Excellent hike with a beautiful view your reward after steep climbing. Spikes needed in some areas today. Not all the great arches are in Utah!

Hiked this mid day on 12/22. Light snow to start then clouds and sun. Second half of the trail is steep and a fair amount of ice. Most people were in tennis shoes but we saw quite a few falls. We were happy to have poles and microspikes. The views from the arch are amazing. Great photo opp.

Nice hike, more moderate than hard, I was able to hike up and down in less than an hour, but definitely take some time to hang out at the top. Views of the flatirons are nice, and Boulder if you’re into that kinda thing.

Hiked this today on 12/20. I wouldn’t say this should be rated a “hard” hike; more like “moderate”. We started off on the West ridge route up to Sanitas and then came down the East ridge route. You start the ground running on a great incline most of the way, and then it lets up a bit. No snow or ice whatsoever on the West ridge, nor at the summit, but there was black ice on the East ridge route when we descended that way. So if you are wary of ice, then take the West ridge back down after summitting. But we managed fine in hiking boots. The hike in general is a good one. Great workout for sure.

Hiked this today on 12/20. Great hike, with a steady incline the whole way (except near the arch). Would have been awesome if it weren’t for the ice that covered most of the trail. We only had hiking boots, but poles and traction would have helped. It’s manageable with just boots, but watch your step, and be wary for black ice. No snow on the trails as of today.

Good trail for an afternoon hike nice and close to town. We did it when in town for Thanksgiving and it was a nice day. The view from the top is ok. You can see some snowy peaks if you look west from the top. The hike up is pretty steep; it's a good workout trail. In November, it was pretty icy on the way down to the valley where some parts were on a north-facing slant.

Went early Sunday morning (12/9). Microspikes would have been nice, but by no means did you NEED them. 90% of the hikers were wearing tennis shoes (including me). Just take it slow if you are nervous about slipping.

Wouldn’t say is hard- solid moderate. Short. Trail crosses rock slide which is fantastic. Trail takes you to back of first flatiron, which cool, is bit of anticlimax...
