Dog Hiking Map

Arrived early enough in the season to be the only hikers on the trail. Also, no boaters in sight just a few people fishing on the banks. Pretty easy/moderate hike with lots of rocks but great views. Dogs will love this one too!

Good view of the distant snow-strewn peaks and a reservoir. Wildflowers are starting to emerge now. Not a lot of scenery to look at unless you're at the very highest point of the trail, but besides that it was an easy trail with decent enough reward at the top. Very few people hiking on a Monday afternoon. Only passed two groups of people.

Once you get to the point on this trail where it turns into a road that heads back to the parking lot (clearly marked with a sign) and there's a building where the reservoir water flows out into a river, I'd also suggest heading up the 'Hummingbird Switchback Trail' that goes up to the Ralph Price Reservoir. It's short and you get a good view of the water, and can even follow a trail all the way around the lake if you want. From there you can take the road that goes around the reservoir a bit and also leads back to the parking lot.

Forgotten Valley is actually probably only about 3.5 miles round trip. I’d rate it as moderate... plenty of uphill. Beautiful bright blue pond and old houses from the 1800s at the end of the trail. Went 4/16 and no snow. Make sure to keep track of where you turn as there are a few times the trail branches off.

Amazing views especially the loop at the top but I would not hike this trail again. We got passed by 50+ bikers some who were nicer than others in sharing the trail. Biker experience took away from the hike. I would definitely not recommend taking a dog on this trail.

Pretty hike and a good workout but WAY too many mountain bikes. No exaggeration, we passed (or got passed by) 75+ bikes today. We hiked about 8.5 miles (Belcher to Mustang to Sawmill and back) and there were bikes throughout the entire way.

Fairly easy hike but the terrain is rocky.

Nice hike. Did this last September. Definitely on the easier side of Moderate. Nice and shady for most of the hike. The dam is awesome and a great place for lunch. Some nice views along the way as well.

Beautiful rugged hike. You start out the first half mile or so on a service road but it’s going along side the St Vrain creek, so the scenery is still beautiful. Also I’d say the last 1.5 miles of the loop are coming back down the service road, but again, still feels plenty secluded. We went on a Wednesday and hardly ran into anyone else and parking was not an issue. Once you take the trail (it’s on the left off the service road) it is pretty steadily inclining for a while. Gorgeous views of Longs Peak at the pinnacle. Would definitely do again!


Snow was not a concern for the most part, but I will say there was about a mile long stretch where I wish I had my spikes. still totally doable, but would have made things a little more enjoyable.

with the warm weather coming I assume beautiful conditions from here on out.

Loved the scenery on Sleepy Lion Trail! Make sure to turn left onto the trail off the main road. I accidentally made a left turn into Hall Ranch and turned my 5 mile hike into over 10 miles, but a lovely mistake! I saw over 20 deer close-up and a huge mountain peak before returning to Sleepy Lion Trail. Also saw eagles, wildflowers, and a rabbit. Finally hit the dam and took Hummingbird Switchback Trail up to Ralph Price Reservoir. Absolutely beautiful around 430pm! Took the road back to the car and enjoyed walking by the river.

Beautiful trail on a lovely day with my pup. There were lots of hikers and bikes at lower elevations on a Sunday afternoon, but the trail cleared out as you got higher. A really great hike!

Quick morning hike with lots to look at. Trail was essentially dry on 4/7/18 which is always a plus.

Got to the lake right at daybreak and sat there listening to the ice melt under the surface. Was an awesome experience!

worth the hike! the last mile is tough but the views are spectacular. This is my favorite hike in Colorado.

Good hike. Don't let the beginning fool you, the last mile is a heck of an elevation gain. We were pooped by the end of it. Gorgeous views.

Parking is very limited so get an early start, especially during tourist season.

Up until the bridge (even a mile or so after), was packed snow, no traction or snowshoes needed. After that, started to punch thru and didn't even make it halfway and lost the trail at one point due to snow drifting. Recommend snowshoes after bridge based on conditions today.

Great time, still pretty deep snow near the end.

As someone mentioned before me, this mapped trail leads to windy peak - which is beautiful. Moderate difficulty, good view from the top. Last about 0.7 mile had packed icy snow. Extra traction would have been helpful, especially on the way down (I ate it once). But doable just in boots. Good hike!

The title Forgotten Valley is misleading as the map shows a route to Windy Peak; Forgotten valley is just to the west of this route and sings along the way will indicate. There is a state park fee to enter this area and parking is available for about 20 vehicles near the trailhead. This route begins on the burro trail and ascends to a junction with mountain lion trail. You take mountain lion up to the north shoulder of windy peak and then it reconnects with burro. Signs lead the way to the summit which raises up to around 9,000ft. There were a few snowy patches and micro spikes would have been helpful for the last half mile. There was skipping and sliding today. Windy peak lived up to its name and provides amazing views to the west across golden gate and to the snowy high altitude peaks beyond. The whole journey took me just under 3 hours including some rest time at the top.

Great time with my new pup Misha, she did really well for her first time in the mountains!

This was the best hike I've been on since my last 14er. The ist 4-5 miles is steadily uphill but doable if you're in decent shape. My 21 year old daughter led the way with our dogs, Miller (living the High Life) and Ellie. My 14 1/2 year old wire haired mutt that keeps going and going...... The views are expansive and the trails are either dirt or dirt/rocks. We began on the southern part of Belcher Trail, hiked a few miles and turned left on the Mustang trail. Once the Mustang Trail hit the Sawmill Trail we continued to climb a not too steep pather until we reached the Sawmill Trail campsite near 7500'. This is the high point of the hike. The campsite is amazing! It has excellent tent sites, fire pits, picnic tables, free firewood, clean restroom metal bear bends, No one was camping but my daughter and I decided to backpack and camp their a night or two on our next visit. We did come across a couple of people riding horses, a handful of mountain bikers, runners, and small groups of hikers throughout the trip. But we were alone for a good portion of Mustang and Sawmill Trails. Sawmill eventually intersected with Belcher Trail again and it was downhill from there. There was some snow in the higher elevations but not enough to pull out crampons. The trail was dry for 97% of the hike. We began at 1:30pm and ended around 5:15pm. We hiked a total of 8.8 miles, climbed 130+ floors, and took over 20,000 steps. Overall, it was one of my favorites. We're all going to sleep well tonight. Adios for now

Saw literally 5+ moose early last fall. One of the best- really not too bad.

3/31/18. Trail was mostly clear of snow in the sun spots, where there was snow, you didn’t need micro spikes. Not many views, but a nice hike

Back side of the trail was still pretty snowy but no need for spikes!

Currently mostly snow covered with a hard pack. No spikes or snowshoes needed!

Still a rewarding trek on snowshoes this week, but starting to get slushy down low. No bare spots by any means, but made for an icy trip back at the end of the day. Still parking at the HWY14 turn off for The Craggs at this point which adds some distance/time. Always love this hike!!

Great hike! Barely any snow. Saw a moose!

This was a very pretty trail to walk. It had very little elevation change, parallels the lake the whole time, and I only saw a few others on the trail. Very enjoyable!

This is a beautiful hiking trail! I would not recommend it for trail running however. It is a very rocky path about 75% of the way. Yay hiking/nay running.
