High Plains Trail

Only One Connection North Of Quincy, Closed At Ireland Way To The South

October, 2021 by jadc55

From Quincy north this is a nice wide cement trail that is in great condition. Only a gentle climb here and there, great views, and no traffic issues make this trail a pleasure to ride. However there are no connections until the end at Stephen D Hogan Pkwy. Hampden is an overpass to the trail and 470 with no connection, and Hampden is not bike friendly at all at this location. Jewell is a tunnel underpass. On both sides there are dirt construction roads that are no longer being used and are quickly becoming overgrown with weeds. You can still access Jewell but beware the goat head stickers and be warned that Jewell is only semi bike friendly. There is a shoulder but traffic flies by at highway speed. The trail ends at SDH Pkwy. Here there is a soft trail on the south side of the Pkwy and at highway 30 (where SDH becomes 6th Ave) you are fenced in and forced to take the underpass. After the underpass you can continue on the Sand Creek soft trail or ride up a dirt path to 6th Ave. On the north side of SDH you can ride the shoulder but after highway 30, while on 6th, the shoulder disappears for about a half mile and again it is a scary ride.

From Quincy south you start on an asphalt road then back on cement. It is a climb to Smoky Hill Rd. The crossing is on grade and there is a lot of traffic. Right after the crossing is a steep decent, then a climb again as the trail and 470 are on an overpass of Arapahoe Rd. (You can access Arapahoe by taking a descending trail to Ponderosa and that to Arapahoe) Another climb to Gartrell Rd. where you have to ride the sidewalk to the light at Dry Creek to cross, then back up to the trail. And finally another climb past Liberty Middle School to Ireland Way where the trail is closed behind a locked gate. You can see the trail continue but there is no safe way to cross Parker Rd at Cottonwood so the trail is closed here. You can read more here:

Loveland Recreation Trail

The Gap is Done

October, 2021 by dvjames48

The trail work on the Northern gap is completed! It was done sometime before October 4th, 2021. Instead of riding on a scary West 57th Street there is a safe concrete multi-use path. My wife and I love this 18 mile loop trail in Loveland even if we do live on Boulder.

Unnamed Creek Trail

My Second Trail

October, 2021 by jadc55

When I first got my bike I had no idea all these trails existed. A friend came over to show me a few things and we discovered the Toll Gate Trail by accident. Later, while riding the Toll Gate, I saw a trail map by Hutchinson Pond and discovered the sidewalk that led to the Central Rec Center was actually the start of the Unnamed Creek Trail. The trail has a signaled crossing at Tower, follows the creek, loops through Flanders Park, and runs along the creek again to the soccer fields near Hampden and Himalaya. Technically the trail ends here but there is an underpass at Hampden and you can hook up with the Conservatory Trail south to Quincy. There is a climb to Reservoir Rd then a descent back to the Toll Gate for a short loop. You can also go north on Conservatory to Power Line to Toll Gate for a longer loop.

Piney Creek Trail

Beautiful and not crowded

October, 2021 by loridishneau

It got a little bit confusing in a few areas for those of us who are directionally challenged. But it was a fine fall flat ride. ¿

Long View Trail

Great Ride,I loved it

September, 2021 by alianna222

I did the Long view trail for the first time and it was a challenge. It has some good sized hills. I did the long loop from Laporte to Loveland over to Boyd lake and back to north Fort Collins. I started from my home town of Laporte and ended north Fort Collins near highway One. 34 miles.

Poudre Trail (Fort Collins)

Great Ride and Lunch

September, 2021 by rxrayinc

We started at the Environment Education Center and rode to Bellvue. Even with a stronger than mild wind the scenery kept my mind off the wind. (Coming back with the wind was great!¿) On the way back we followed signs to down town And found, Tom Kha Thai Asian Bistro. What a delightful restaurant and reasonably priced for lunch. We continued through town across the college campus and found the Spring Canyon Park trail. Spring Canyon was beautiful. We found a blow snake more than half the path width! Back across town to the truck. Overall a 40 mile ride!

St. Vrain Greenway

easy ride

September, 2021 by rxrayinc

Both the main trails in Longmont are flat, concrete and perfectly maintained. There is currently a bike detour to get between the trails but it is hard to see going NW.

Corridor Trail

fun and short

Farmers' High Line Canal Trail

ban on ebikes in 2 jurisdictions

September, 2021 by jpdakine

Beware Cherry Hills and Greenwood Village portions of this trail. These jurisdictions have banned ebikes and are bike police monitoring

Cherry Creek Regional Trail

2 Trails in One

August, 2021 by rebpls.co

The southern 26 miles (upstream from Cherry Creek Dam) is definitely 5- Star (Arapahoe and Douglas Counties). The southern part has many areas in natural and beautiful settings and the use is moderate. Very pleasant. Parker and South-Suburban does a great job keeping them nice.

The Northern 14 miles (Downstream from dam) is 3-star (Denver City & County). It is urban, lots of local road traffic as well as high use. Watch out for the bikers and the Lance-Wannabees who will not call themselves out as the pass and ride between 15 - 30 mph. They can ride in pelotons dominating the path and get angry if you are in there way. Many though are courteous. Be very careful though if you are out with your kids and leashed dogs. There are also an increasing amount of e-bikes as well that are riding fast even though they are forbidden on the trail. Denver does not patrol their paths and trails

High Line Canal Trail (CO)

Walked all 71+- miles both ways.

August, 2021 by rebpls.co

Good trail overall. No trail between mile 9.5 and 11.25. Do not try to walk on Santa Fe here - that is suicidal. Best trail (in the rich neighborhoods) between Hampden / CO Blvd to Broadway-Very Nice. Denver parts are so-so to OK, same with Aurora. Only a few mile-post markers missing. Watch out for bike riders, many feel they own the trail and maybe 5% call out before passing you. I walked all the trail after having hip replacement surgery between April -August 2021.

Kipling Trail

August, 2021 by peenfre7368
