The Colorado River Trail is a trail that starts near the Grand Lake Golf Course and ends at the Colorado River. There are many short but exciting singletrack bike trails that crisscross the Colorado River Trail, making an endless number of loops that can be done in this trail network. Please Note: The trails are available on a seasonable basis. During the winter months they are used for the Nordic Center skiing and snowshoeing trails and a trail fee is required.

There has been a fire here.

Do not hike this trail. Only hike this trail if you want a rude man to drive past and threaten to call the sheriff on you when there are no trail closed signs posted. Come back in ten years or so.

This trail looks terrible. I understand now there was a fire and it’s very apparent. Do not waste your time walking through the dirt and ash this year.

What wasn't damaged by the beetle kill mitigation project is now sadly burned due to the "Golf Course Fire" in late June early July 2018. It will hopefully be a great area to hike in less then 10 years.

We drove to the trailhead and it was closed due to a 20 acre forest fire. It was devastating to see. Hope to try again in the future.

Great little trail that saves the best for last. I agree the damage from beetle kill is distracting, but being able to take your dog along makes up for it. We saw a moose hanging out by the lakes, which offered great photo opportunities.

Too much damage and debris from pine beetle mitigation work. Trail rerouted away from many of the best parts. Very disappointed.

Loved the hike and the CO River was a nice break 1/2 way through the 4 mi hike. Didn’t see any moose but was on the lookout since we had our dog with us. Sad to see the forest hurt by the beetles and fires.

Starts off in the woods and covered for a while with bits of the river until you are right along side of it. We ran into MULTIPLE foxes on this trail so keep your wits about ya.

We would have given this trail 4-5 stars last summer. Nice ponds, numerous trails, dog friendly, and even saw a moose that forced us to go through The Maze. In fact, this is where my profile pic was taken. However, went today and at least the entire north along River Trail is completely logged and piles of debris are covering the trails. Not sure which trails are still good. I would stay to the east and take Warbler trail to the south of The Maze. I hope at least the east and south are good.

All the trails are surrounded by dead or cut down trees. Not an interesting hike at all.

good trail. mountain biking. lots of options

It's a nice mild hike, nothing too steep or too hazardous. There's a lot of criss-crossing trails to choose from, we followed the River Trail, which has a nice payoff. It seemed like there were a lot of cars in the parking lot, but we only ran into two people and a family of mountain bikers. Downside: there is a lot of fallen timber & logging, and swaths of it are kinda depressing to see. Saw two deer, plenty of chipmunks, but no moose or bears.

Fun, but not for family. Lots of rocks

Nice hike but due to the pine beetle - significant tree damage along hike. Ending spot is nice place on the river.

The trail was in amazing shape and really well maintained, so if this review was just based on that I would give it 5 stars! However, there were sooo many downed trees that it looked like you were walking through some sort of post apocalyptic movie scene. For that reason I can only give it 3 stars.

Horrible trail. They are logging everything down around this trail but no sign anywhere telling you this. Not great views whatsoever

Great hike! Signs everywhere to help guide you. Fairly easy trails. There are lots of resting spots with benches and views. The river of course the best part, great place to grab some grub. Great for dogs. Found it to be lightly trafficked, always that noontime though gets busy.

Good level trail. Some sections are closed due to logging activity. Saw no wildlife today.

Tuesday, May 30, 2017

Lots of beautiful ponds to hike around, great for kids and dogs. Not difficult with lots of signage, but easy to get turned around as there are lots of trails and logging roads. Ends near the Colorado River with some nice views.

Don't try this in winter... as far as I can tell the trail is not used in winter but does intersect with trails groomed by the nordic center. We snowshoed a short while following some other tracks and when we came back a grumpy nordic center employee drove to the trailhead to tell us we should have brought a trail pass. Not the best experience.

great trail to take dogs on. some signs are kind of vague. bring plenty of water.

A great easy hike with several elk. The Red Mtn. trail was tougher and mostly uphill, but the nature was worth it, so was the gorgeous creek!

Beautiful marshes blending into lily pad ponds reminiscent of monet's paintings! The trail can often be confusing, leaden with signs which seem to only make it more confusing. The forest is thick and beautiful yet also paranoia inducing. Large boulders, fallen logs and a carved wooden bear all make for small heart attacks :). Keep an eye out for moose as you most definitely will see one or two. Early June towards the end of summer is a dangerous time for moose encounters, as often the mom is rearing babies. Be careful, I cannot stress this enough, moose are not afraid to stomp your head in!!!!!! Keep talking somewhat loudly throughout the hike to avoid spooking anything. Other than that, a simply gorgeous hike that keeps the mind and body in constant movement!

A little bit rocky and technical on beginning of single track. Once you get further into trail, you can join up with double track which makes for a more enjoyable experience. The trail takes you to a beautiful spot right next to river with benches and bridge crossing.

By itself, the Colorado River Trail is not particularly exciting. It is mostly flat, and has both single track and double track. However, it is crisscrossed by many loops and sections of single track bike trails. All intersections are marked with both the name of the loop and the difficulty, ranging from easy to most difficult. Not many views because you are in the forest the whole time, but the riding is very fun.
