About This Trail

actions now above photo
 
Betasso is a quick smooth loop through forested hills, with plenty of tight turns and speedy downhill sections. The climbs and descents alternate enough to allow even a beginner to have a good time on this track. In some places the trail is cut right into the side of the mountain, so you are looking at a serious drop off if you\'re not paying attention. The trail has some nice views and is well maintained. The trail directions alternates monthly, so make sure you read the signs at the trailhead. Regardless of the trail direction, you will start off descending, and finish up climbing. There are two main (directional) loops: from the main parking lot you will start on the canyon loop, about halfway through, there is a connector trail that leads to the flowy, somewhat less technical, Benjamin loop.

Bikes are not allowed on this trail on Wednesdays and Saturdays.

Review: Great mix of ups and downs for front range riding. Also enjoyed the shade during the middle of the day.

Review: I like this trail a lot, it gets a ton of traffic on the weekends as others have said. not very technical, great for beginner riders that don't want an easy trail. be careful on the 2 way section that connects the two loops, there are a lot of blind corners and not everyone is looking out for oncoming traffic.

Review: Great trail system and I really like the one-way system that's being used. Trail in good condition and is a good mix of climb and descent in and out of the trees with very little in the way of rock gardens. The loops are easy to do over and over to increase mileage and there were a number of bikes out so there was always someone to play with. The bike patrol was out and he was very helpful. Sure would be nice if we could ride the trails one weekday and one weekend day without hikers and runners just as they have two days a week without us.

Review: Great ride with nice views. Both the Benjamin and Canyon loops are directional which minimizes passing and makes for great riding. The Benjamin loop is a bit less technical than the Canyon loop.

Review: This place has so much flow and the maintenance is great. The path is very buffed out so it's not much of a challenge to your technical skills. The rolling nature of the trail makes it seem like you are doing a lot less climbing than you actually are. I would say 90 percent of this trail can be done on your big/middle ring. I subtracted one star for the crowd. Don't come here expected to find solitude, there will always be someone riding up behind you or someone ahead of you that has to move over. Tack on a couple laps of the Benjamin Loop to up your mileage/vert.

Review: Great balanced trail, with plenty of rolling sections, some technical stretches, and a couple good flowing uphill and downhill sections. A really fun ride with some nice views. The connector between the two loops is the only cautionary part, where traffic goes both was on a narrow trail with some blind turns.

Review: Im new to the Denver area so with that I like this trail for its flowyness and relative low elevation. There are some technical sections but nothing that required a hike n bike. Beautiful views and the trail is well marked. I definitely will come back here to check it out during warmer weather.

Review: Doesn't hold a candle to Picture Rock, IMO, as it's not as fun on the downhill nor as challenging on the uphill, but it is extremely fun and flows very well.

Review: the best flow trail around boulder--better than picture rock, heil ranch or hall ranch.

super flowy, pump trails, no rock gardens, some jumps, good climbing.

great trail for XC training and for people that want to ride something that's fast and flows.

the benjamin loop is sooo much fun. great little loop that allows some fast progression in riding skills.

absolutely no hike-a-bike nonsense.

canyon loop had harder climbs and a fewer more tech sections.

betasso link trail is the most technical.

Review: Got a free demo of a Kona Satori 29er from Full Cycle in Boulder so I thought Betasso would be the perfect trail to try it out. The bike was plush and fast and a great climber. This was my third time on Betasso this season. Had a great time on the Kona and the weather cooperated with some nice cloud cover to keep it cool. If you're in Boulder and have never ridden Betasso give it a try. Go up Canyon Blvd. towards Nederland and take a right on Sugarloaf. Climb for a few minutes then take a right when you see the Betasso sign. Trail is on the left. I only point this out because I got lost the first time looking for the trailhead.

Review: First time riding at elevation, and first time in Boulder. Wanted to get my feet wet and this trail looked enjoyable and a safe bet. I rode the connector off 4 Mile Road, both loops, then the Canyon connector. Nothing really hard or technical besides a few exposed rocks in the trail and the last little bit of the Canyon connector. Defiantly walked the bike down that little part. I live in the Midwest, so this was not only a good time, but a great fast singletrack with do-able climbing even on non acclimated lungs. Totally recommended.

Review: No extreme technical sections but a fun trail. Can't ride on Wednesdays or Saturdays and the lower loop changes direction. The upper loop is more fun than the lower section and the connection trail is better than both loops.

Review: Been riding this regularly for many years. Keep coming back for the great views and fun flow (particularly when trail is routed clockwise). Nice 50% decent, 50% climb. Tend to ride 2-3 fast loops or more given the relatively small (3 mile) loop... However, since the Benjamin loop was added in July, 2011, Betasso has taken on a new dimension. Awesome new 3 mile lollipop addition! Fun in either direction with minimal climbing and a sustainable and thoughtful design that expands on Betasso's original feel and flow. Very impressed! Add the Link Trial connector from Boulder Canyon, the occasional wild turkey, deer or bear sighting and you've got a nice all-rounder conveniently close to Boulder... It tends to be busy, particularly when students are in town, otherwise highly recommend, especially for those new to Boulder's trails...

Review: **I am reviewing connector trail only** (is there a separate thread? does it not deserve one because its only 1.3 miles? it's def a double black diamond) So my second day mtb in boulder friend says, there a trail we can hit from the house. I think, cool-let's go. We take the 'creek trail' (paved), past the hills, then up a curvy road, and arrive at the trial head that is basically straight up a cliff. wtf. I walked my bike up 3/4, then sat out the top loop so I could catch my breath and prepare for the insane downhill, which i also walked my bike down about 1/4 for fear of losing my face in a nasty spill. I will compare every future trail I see to this one because it was the most insane mile of my life. when you see other riders jamming down the mountain in full armor and face mask, be afraid, very afraid. I hope one day I can stay on my bike the entire time.

Review: Yep the normal trail is great. However I will write about the new section. I must say I don't like most things boulder, a city full of college students andMidwest transplants just makes me angry. However the way the new trail was put together is not only really fun it's smart and sustainable. I did a few laps and I will be back again, good job boulder.

Review: Easy, potentially fast mostly singletrack right outside of Boulder. The downhill is fun, and the uphill isn't overly strenuous. One way bike traffic(alternating directions every month) makes it a great place to run a few laps, but hikers DO go both ways, so take care. I prefer the clockwise flow, so I tend to run it more often when that is the direction of the month.

Review: This is a decent trail. Great for a close ride, and if you are tight on time you can make several loops. We averaged about a half hour per loop. However, figure I will post it one more place because I was retarded and missed it on here and at the trailhead, they discrminate in boulder, NO BIKES ON WED & SAT

Review: Great track near Boulder. I rated it more difficult even though most sections could be rated easiest. There are a few tricky narrow spots. Still, as long as you are aware of what days it's closed to bikers and can handle the afternoon/ weekend crowds, great track!

Review: This Trail is awesome simply because you can circle it as many time as you want. The only disappointing part of the trail is that you are forced to ride 1 way which is changed about once a month, and 1 way is more fun that the other.

Review: This trail reminds me of the practice loop at Slick Rock,short but still an awsome trail.It has a really cool feel about it with the smooth tree lined singletrack and gradual climbs and downhills,and the nice cozy feel of being out in the woods.Not too much technical stuff but there are some roots and rocks in places that keep it from feeling like a gravel bike path.

Review: This is a nice trail near Boulder but do to heavy use it has a number of ruts which can be dangerous so I would upgrade this trail from easy to intermediate. I actually find this trail harder to do than Buffalo Creek because of the ruts. Maybe I am prejudiced because I fell down the side of a hill after hitting a rut. I would not tale a raw beginner on this trail.

Similar Trail: Picture Rock much smoother

Review: I really enjoyed this loop. It was a quick and dirty jump back into mountain biking for this year. I will definitely be using it in the future for fun laps. However, be warned if you are not familiar with the trail, be careful not to go down the Boulder canyon connection trail (you will know it if you cross over a street). While it definitely made my ride more exciting and challenging, it is off course as far as if you intended a breezy loop.

Review: This is a good trail to get newbies excited about the sport. It's a pretty ride, there's nothing scary, but it will provide just a bit of challenge for the uninitiated. It can be fun for others as well as there's an extended climb which can all be done in the middle ring. Ultimately, the short length makes this one not worth going out of your way for.

Review: This trail is good. Not great but good. Its proxmity to Boulder gives is a couple points but the ride itself is nothing special. They have designated hiker only and biker only days (which I appreciate as much when I'm biking as I do when I'm hiking) so make sure you find out which day it is before you head up. This is a good place to take beginners, though imo, Mud Lake just a few miles up the canyon is much better for that purpose.

Review: This is the only decent singletrack I have reached from my doorstep without bumming a four wheeled ride. If there are more I would like to know. I have not cleaned the first rocky climb begining at the railroad bridge, but will someday....when and where the rainbow ends. The alternative is riding a few more miles of blacktop to the begining of the hilltop loop. The trail gets busy and dusty, pack along some dust covers for your eyes if your not in the front.

Review: Good trail to hit at lunch or when you are short on time. Best part of the trail network is the connector from the canyon rd. (right before the tunnel). A pretty good workout to ride from Boulder up the creek path, hop on the road, up the Betasso Link Trail then do a lap or two and head back. The uni-directional trail is fun to rip down, just be courteous to hikers as there are already closures to bikes on Wed. & Saturday.

Review: I rode this in a clockwise direction . Some how I rode the whole trail accidentally in the big ring. This trail is so smooth, you can get going blazing fast. I've only done it once after having ridden the Switzerland ride. I am looking forward to riding it counterclockwise as friends seem to think that is the best direction.

Review: Betasso is a popular trail for racers to go to work on speed stuff. It's narrow so it's uni-directional, but that shouldn't stop you from trying this trail. It's a fast fun ride on some of the finest singletrack in Boulder. Riding counter-clockwise, I enjoyed the long two miles of smooth, twisty descending, and even like the last 1/5 mile of climbing because it really gets your heartrate up if you try to maintain speed. I haven't ridden the trail clockwise yet, but the flow of this trail is so sweet, I'm sure it's just as much fun in that direction.
