Recent Trail Reviews

Fossil Creek Trail

highly recommended

December, 2017 by auerbach_j

Did the western section of this trail only and as an earlier reviewer noted, it is beautiful. It is rare to get such a nice paved (concrete) trail in the open grasslands. During its meandering course, it is relatively far from roads/houses until you get near to the western end. Though overall it climbs from east to west, the path winds and undulates in tune with the landscape making it fun and interesting traveling in both directions.

Wonderland Creek Greenway

Looking forward

December, 2017 by auerbach_j

This path is getting a major face lift with new and redone sections between Foothills Pkwy and 28th St./Palo Pkwy slated to be completed Spring of 2018. Along with the existing sections, these improvements will make this greenway path one of the best/most convenient in the Boulder system.

Goose Creek Greenway

Another great Boulder path

December, 2017 by auerbach_j

This is a very good east/west trail that provides access to many other trails/areas of Boulder. It is one of the relatively newer Boulder paths so is nice and wide and in good shape. As with other Boulder paths, there are some blind spots and other path users to be aware of. There is one road crossing at 47th St. that is usually not too bad. Watch out for crazed Prairie Dogs darting in front of you in the open eastern portion!

Accordion

Elmer's Two Mile Creek Greenway

Good connector

December, 2017 by auerbach_j

This is a good little north/south connector trail. It is one of the relatively newer Boulder paths so is nice and wide and in good shape. As with other Boulder paths, there are some blind spots and other path users to be aware of. There is one road crossing at Glenwood Drive that is not particularly well marked and can be a little sketchy at certain times due to car traffic.

Boulder Creek Path

Classic

December, 2017 by auerbach_j

The classic Boulder multiuse path. It is a very scenic cruise for its entire length. The path is usually always in great shape (unless recent flooding, blow down, or construction) and there are no street crossings (all are underpasses). Going west to east (down creek) you can get your speed up in areas but be cautious as there are some blind corners. More importantly, there are a lot of other trail users, so best to take it easy. Note that there are newly redone sections in the western part of town that help segregate walkers from wheeled traffic by having specific, marked "lanes" for each. Still, as always, pays to be alert and courteous.

Bear Creek Path

great path

December, 2017 by auerbach_j

This is a great little section of trail and is quite pretty as it follows along Bear Creek. The path is usually always in great shape and there are no street crossings (all are underpasses). Going west to east (down creek) can be a fun, quick ride! There are some sharp and blind corners that warrant some caution/awareness. Like other Boulder paths, the only downside is occasional encounters with other "traffic"... bikers, hikers, moms pushing baby carriages, roller bladers, dogs off leash, etc. Best to be on the alert and courteous.

Poudre Trail (Fort Collins)

Excellent “urban” trail

December, 2017 by auerbach_j

Though this trail is in the city of Fort Collins, it is hard to call it an “urban” trail as most of it twists and turns pleasantly through the pretty woodlands and open grasslands along the Poudre River. There are many parks and nature areas along the way. The sections that are in the city proper are still very nice and do not give the ugly industrial scenes or heavily residential views other urban trails usually end up providing. Except for a couple brief sections, it is not very close to roads. There are only 2 road crossings that have to be made. Trail itself was in excellent condition with some newly reopened/repaired sections. Only place where there was construction was at the far western end in Bellevue - a couple hundred yards from the end of the trail anyway.

Rock Island Trail (CO)

Fantastic from Union to Powers

December, 2017 by 8 wheel transit

Wide concrete trail from Union east to Powers. Several sections were recently reconstructed. There are a few street crossings and an underpass at Circle Dr.

Glenwood Canyon Recreation Trail

Glenwood Canyon and Colorado River Up Close

November, 2017 by mbcallawa

I drove I-70 west to Glenwood Springs in order to bicycle the Rio Grande Rail Trail (from Glenwood Springs to Aspen, a former candidate for the Rail Trail Hall of Fame). I was disappointed to be driving through such a spectacular canyon at high speed, not able to enjoy the canyon and river views because all my attention was riveted on the Interstate traffic. At Glenwood Springs, I asked at a bicycle shop where the start of the Rio Grande Trail was. The bike shop guy said I should definitely check out the Glenwood Canyon Trail, too, which I did the next day. Glad I did! There is no better way to enjoy the river and the canyon scenery. I relished seeing what I had missed in my car. The Colorado was in June flood, and one section of the trail had several inches of water on it - that's how up close and personal you get to the massive rapids. There is one brief section on regular roads with some short hills, but they have little traffic. The rest of the paved trail is right next to the river with a gentle grade east, up river. You can see and hear the railroad trains on the other side of the river, and you are adjacent to and below I-70 on the north bank. This is not a wilderness experience, but the architecture of the road and trail on one side, and the RR and tunnels on the other are interesting in their own right. Towering over it all are the massive red canyon walls. Overall it was a sublime experience; an ideal cycling day ride (28 miles out and back), car free and carefree, with spectacular canyon views and roaring rapids.

Glenwood Canyon Recreation Trail

look beyond the interstate

November, 2017 by auerbach_j

I pretty much concur with the other reviewers comments but I have to knock off a star for the proximity to the busy, noisy, ugly interstate. If there was no super highway it would be a 6 star ride! But to be honest, if there was no interstate there would be no path. If you can keep your focus toward the nicer natural side of things, it is an incredibly unique and scenic place and fun, stress free riding. 

¿This is not a flat, riverside trail but it is not that difficult. As to be expected, it climbs going up river with the western half (up to Hanging Lake) having more climbing (a few hundred feet total). The eastern half (east of Hanging Lake) is mostly flat¿ but is a little more exposed to the winds, and the winds tend to blow pretty good out of the west through the canyon. So even though you may be going downriver/slightly downhill in the eastern half, it can be some work if the wind picks up. 

¿At certain times of the year (fall/winter), sections of the river are de-watered (dam is closed).... it looks kind of weird and there is no whitewater symphony to drown out the highway cacophony.¿ Guess that makes up for other times when there is an abundance of water and it can be over the path! ;-)

Being a relatively narrow and tall canyon means not a lot of sunlight gets in at certain times at certain places. On hot summer days this is great; on cooler shoulder season days, be prepared for some chilly spots.

Colorado Riverfront Trail

Nice and pleasant

November, 2017 by auerbach_j

A nice and pleasant, flat ride especially if you keep your focus toward the river and not the usual urbanization or industrial influences or highway hijinks in the opposite view direction. Brief sections have less intrusive stuff and more natural beauty than others. Only climb of note is the short easy one to Eagle Rim Park where you can take a lap and do some tricks in the nice bike park there. There is a very good overlook of the entire Grand Junction valley there too.

There is some great public art, "graffiti-like", along the way too. 

This area of Colorado can be exceptionally hot in the summer. But that means it can be really pleasant in the cooler months and very ride-able on nice winter days. Given the abundance of vegetation along the river course (lots of big Cottonwood trees), it would be spectacular in fall when the leaves are changing. Spring would nice too with it all greened out and likely lots of birds.

Bear Creek Trail (Denver)

Inline Skating Review

November, 2017 by wmloving

Starting at River Point, near Regal Cinemas Stadium and 85/285 intersection, the first 1/2 mile or so along the golf course is 7-8' wide smooth concrete, with 4 wood plank bridges crossing the creek. The next 1/4+ mile section is narrower, twists and turns a bit, and is combination of somewhat uneven asphalt and older concrete, a section of which is pitted on one side from winter weather. I would recommend skipping over this section if you are an inexperienced skater; experienced skaters should be fine. From S Lowell Street on the trail is newly paved, smooth and wider (9-10') and makes for wonderful, fast skating with many places to stop for a break. If you want to skip the first section, consider starting at Bear Creek Park. I didn't travel to the end but will update my review if the western parts have any issues for skaters.
