Cherry Creek Regional Trail

Well Designed but Crowded

May, 2018 by razryan98

Trail has bikers, walkers and joggers with heavy usage. It's relatively flat and any novice can do it. However be warned, there are numerous bikers who ride at speeds over 20mph (posted limit of 15) and don't care to slowdown for congestion or warn people being overtaken. While every ride is enjoyable, this one was more stressful than any I've been on.

Big Dry Creek Trail (Westminster)

Ruined Trail

May, 2018 by an_gel2668

This use to be one of the best running trails until the paved it with hard concrete. The sides are unusable to runners as they are filled with rocks, puddles and leftover concrete. Not to mention I have never seen a stroller/wheelchair since they paved it. Seems like a shame they traded the majority of use for a demographic that doesn't even use it.

Big Dry Creek Trail (Westminster)

Trail enhancements are great

April, 2018 by travisdebell

Great to see the trail is being paved along with the addition of a 4 feet gravel path. Love seeing the city enhancing the trail to accommodate those who need it paved (wheel chairs, strollers, bikes, etc). and those that also want a gravel path.

Big Dry Creek Trail (Westminster)

Concrete ruined the natural feel...

April, 2018 by ginginrini

They put in concrete in the area around 128th and Huron, Zuni. Ruined the nice, peaceful, natural feel. Still blocked off, so can't tell if they at least left a natural path to walk on for dogs and people with knee problems.

Big Dry Creek Trail (Westminster)

Big Dry Creek Trail

April, 2018 by alock2win

Used to be a great trail for runners but this spring they 'improved' it with concrete. So disappointed! Why would they would they go out of their way to ruin such a beautiful area? The Joni Mitchell song comes to mind, "They paved paradise and put up a parking lot".

Just because they had the money to do it, doesn't mean they should. Disgusted.

Big Dry Creek Trail (Littleton)

Great Trail

February, 2018 by docjaakkola_tl

We Parked near South Suburban golf course on the east end of the trail and headed west. Majority of trail was packed dirt with intermittent concrete sections. The trail follows Big Dry Creek the whole way. Wonderful, quiet trail. Only have to cross the road once at Colorado Blvd near South Suburban golf course. The trail goes under the road at Dry Creek Rd, Arapahoe Rd and University Blvd. You pass through a very nice park, Cherry Knolls Park complete with open bathrooms in the winter. We ended at DeKoevend Park near the Goodson Rec Center on the east side of University Blvd. This trail connects to the Highline Vanal Teail here. Loved the trail. Felt like we were in a rural area.

New Santa Fe Regional Trail

Great trail

January, 2018 by philcavinta

My wife and son rode from North gate to Palmer Lake and back. It’s a good track that’s relatively flat as compared to section 16 that my son and I normally ride. Recommend this section for and easy ride.

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!

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.
