Great views from the top ran it at night not too long ago and didn't find it particularly challenging. Lots of camping spots and offshoots to explore. Wish needle's eye was open though. Kinda sucks to get up there and not crossover.

Hello! Oh man.. where are my dog people to help a sistah out? This trail in its entirety is NOT DOG FRIENDLY. I hope All Trails can change to "some parts of the trail are accessible for dogs." I only saw one review with any robust mentioning of dogs and what you can't access here.

The Spring Loop goes north and south, and the south part of the loop does not allow dogs. There are several places in this area that do not allow dogs. I heard from another hiker that this was due to bears...but not sure what would stop them from moving to the other side. My friend and I had to do another part of the trail.. still pretty, but was an out and back instead of a loop. That was disappointing. The sign on the trailhead says no dogs on the south side and on one other part, but All Trails made me think we could do a loop by the above description. Not true! It says you will get fined, and yes, there were rangers out.

Here are the good parts:
FEE: $5 for non Boulder County residents
TERRAIN: Pretty smooth... a few gravelly areas, but mainly nice!
VIEWS: The lush fall colors were in effect. Pretty meadows and some forest areas.

Here are the bad parts (sorry bikers..)
BIKING: Tons of bikers! Beware. I wouldn't wear headphones. NO. Too many trail runners and bikers. At one point coming back down, we got stuck in a spot because there were so many bikers/runners that we tried to pull over for. Most were nice, but they DID NOT use bells of any sort to warn people. I was surprised I couldn't hear the bikers behind me until they were right up on us.

SINGLE FILE TRAIL IN SOME AREAS: some areas are wide open and so nice, but some parts are single file and hard to get off to the side for the fast-rushing bikers.

OVERALL: I was much happier as we moved on into the mountain...less peeps and just gorgeous fall colors. There is hardly any shade, so it is more of a fall hike. Tons of people and the issue with no dogs on the south made for a different hike than expected. I liked the North Loop part very much and liked down to the Fowler part of the trail. Very well marked. Beware though- lots of people and lots of bikers make for a bit of a "look behind your shoulder all the time" effect.

Trail had a large amount of traffic on a Tuesday afternoon and some liter, other than that pretty good.
Great scenery, but no vistas. Trail follows Creek most of the way. Just okay viewing of fall foliage.
Lots of dogs off leashes which I don't mind. Trail is really in between easy and moderate.
Given the 70 minute one way drive, I would only come back if I had dogs with me.

10-4-18 trail is blocked by a couple big trees that have fallen down. also right after the entrance somebody shot skeet and didnt bother to pick up at least 20 to 30 bright yellow shotgun shells. classy... :(

Rock formations and soil color were beautiful. Not much shade.

good trail to take your jeep for a nice drive

pretty enjoyable trail. Couple mostly easy beside the downhill at the back of that trail. I had a wheel up a time or two. You'll want a spotter and or armor underneath

Switzerland trail was not a challenge at all! we saw a mini van out here. look out for lots of pedestrians on foot and on their pedal bikes. IF you choose to go down Pennsylvania gultch, then make sure you have a good 4×4 and clearance. It is extremely tight and very challenging. stock jku Rubicon

Quiet hike on a weekday . Super easy flat terrain . Aspens looked beautiful

Nice walk through the woods along the creek. Aspens were changing but not peak yet. Well maintained trail with lots of spots to sit and enjoy nature. Easy to find.

Had a Great day on Pole Hill. Not a ton of foliage but still great views. Ran in stock 2018 4 runner TRD off road. Some places where clearance was a bit of an issue but nothing I was unable to handle. Had a great spotter which made it possible. Glad I have a front skid plate.

Because it’s one of the few mountain bike trails, I avoid it and let them have it to themselves. Much better hiking trails about a mile into the Eldorado canyon.

Beautiful trail. Well maintained and well marked with benches placed along the trail. As other reviews mentioned as a hiker you constantly have to step off of the trail for MTBs.

I enjoyed this trail. Much of it is through the woods so shade is appreciated on a hot day. Wildflowers we’re past time so I would like to do it in mid summer. Nice walk with dogs. Not difficult.

It’s a great trail awaiting the re-opening!!! A friend of mine introduced me to this trail back in 2003 it was wonderful-Columbines in bloom everywhere!!!

it was fun until the road got to steep. I tried to do this in a can am 850 outlander but didn't make it to the end. ended up rolling the atv. it was still fun.

Lovely little trail, lots of fall color right now. Saw a few people but mostly had the trail to myself. Easy enough for my short-legged dog to tag along. I didn't see a lot of poop bags like others have complained about and found this trail to be very enjoyable. Will definitely be coming back and would bring out of state friends!

A beautiful walk through the forest with minimal elevation gain, but some areas of moderately rocky/uneven footing. Shade is plentiful throughout.

Teresa’s review below offers great directions to use. I’m only giving this trail 4 stars because it is not entirely marked well. After climbing on the dirt road towards the lake past most of the car camping sites, you need to turn left onto the single track trail. It is relatively hidden by grown up foliage but if you have made it to the lake you have gone too far. Once you have made the turn, the single track is great for mountain biking or hiking and is relatively low trafficked since I’m sure most of the campers aren’t even aware that the trail is there. I plan to come back and use it for camping and mountain biking. I mountain biked and would do it again.

One of my favorite trails for trail running. Not super difficult but a nice workout. Pretty views!

Pretty mellow trail. Good for people just starting to wheel. Jenny creek, although now rerouted, is a little more techy if your wanting a bit more of challenge. Took a bit for the snow to fully melt though.

A bit difficult going uphill on the bike unless you're good with super technical / steep climbs. Down hill was a blast tho. Only saw a couple other bikes on the trail, but it was a Monday morning so..

Great trail to start on and practice. This is the first trail I went on off-roading and have been back a number of times since.

From what I can see however, this map only shows about half of the trail.

I'd break it down into 3 sections:

1) The start the Peak To Peak highway to the old station clearing at the Sugarloaf Mountain side.

2) Station to Fourmile Canyon Drive (shown as the end on this map).

3) The trail continues on the other side of the road (marked by a blue sign saying alternative evacuation route) and up to gold hill road.
This section includes the Mount Alto picnic area.

As noted in other reviews there are a couple of other trails off here (Pennsylvania Gulch stands out as being the toughest of the bunch, it's very rocky in places and needs high clearance, 4 low to get through without issue, not really a trail for beginners. The others off of here are on par with the rest of this trail though)

They are very similar in difficulty, there's no big rocks and only a few narrow stretches.
You can generally find a place to pass really close, should you meet somebody coming the other way on one of these narrow places.
Most of it is wide enough for 2 to pass.

For me, not keen on heights at all, there are some places with quite the drop off the side of the trail.
The one springs to mind, is close to the Mount Alto Picnic area, where there is a large stone on the driver side of the trail that looks a little bit like a tree stump, though it's actually fairly wide.
Still it is not that scary, even for me, who has an issue with heights.

My fear of heights is something that off-roading in Colorado is helping me come to terms with! LOL :-)

I have seen 2wd cars on this trail, so it's a really good place to get used to your 4wd vehicle and off-roading in general.
This trail has been recommended as a starting trail by a number of different people and is very popular.

Airing down helps make the trail smoother, though I've done it without airing down (because I am a newbie!).
If you don't have a decent air compressor, there are 2 places in Nederland nearby you can air up at. The Gas station on the roundabout and the Kwik Mart across from it.

Note for the complete new starter to 4x4 offroading:

If you're still not sure you want to start with this one, do the Old Fall river road in Rocky Mountains National park about an hour north of this.
That's an unpaved road and really only needs 2wd, has some awesome views up in the Alpine Biome and it is a one way only road, so no need to worry about passing.
It's not listed on this site for some reason though.

Came here with my partner and dog. we are 20 somethings that live at 5000+ ft altitude and are not in fantastic shape. This was very challenging for me. More so the length than the hike itself. The view by the sign in the valley was more stunning than the top view. we came here labor day weekend and got stuck in all the Estes traffic but only saw about 6 people on the trail.

Pretty fun trail! Decided to take the truck up for her maiden off road trip, and she did great. The trail itself is more advanced than I had anticipated. I've been up the Mount Antero trail many times in other trucks, rated as "Moderate" like this one. This trail is far more advanced than the Antero trail. Scraped the skid plates and running boards a couple of times on this one. Awesome trail with amazing views though! Going again tomorrow with the family!

2013 F-150 SuperCrew, completely stock with exception of 295/70/17 tires.

trails were confusing. ended upcoming out by Nederland high school so to get back to my truck I had to jump on a bus and then walk about a mile south on 119. although, the views of the mountains where excellent!

Great hike overall! But do not go on the part of the trail marked 247D. This part of the trail is completely overgrown and very hard to find a path past all the fallen trees and tall grass. Everything else was a great challenge with a few beautiful vantage points (although not at the highest point in elevation, as you’d expect).

Gorgeous views. Not the easiest but definitely doable- a fun challenge with our twins strapped to us!

This trail is so pretty and it is a very entertaining hike everyone in my family loves it including the dogs. The creek is so fun to play in together!

Poor signage. More of a mountain bike trail than a hiking trail. And the red line on the map above is not the trail.
