Trail Q&A
Rider Questions


Q: Good suggestions above for beginner rides (Arbor, etc.). I would also suggest LB Houston and Corinth Community Park. I would consider those two first timer trails, but fun enough to go back to from time to time. -FredCook

No answers yet.




Q: Hi, I'm a beginner, is this trail easy enough to ride by myself? Is there a site that I can connect with other beginners, interested in riding this trail? Thanks -Nick Abbott

A: HI Nick. The Knob Hills trail is beginner to intermediate, but if this is your first time riding, I would go somewhere like Arbor Hills in Plano, Harry Moss Park in Dallas (Greenville Ave.) or Katie Jackson. Use DORBA.ORG for a reference and location of these trails. Knob Hills can definitely be a beginner trail if you are careful, but there will be some walking throughout - which is no big deal; it is how I started as well, lots of hiking.

Review: Lots of fun mixes of topography, fun features and good bits of smooth XC to get from place to place. Right now the mosquitoes are outrageous and a few trees are down. I came out because I saw a feature I wanted to ride in a video someone posted on line-- I didn't find that feature, but I did get my A€£ kicked by the cardio.

Review: Just an update for this week... loop 3 is a "tall weed fest". Almost impassible due to over growth of the tall 10' stalks that are common on loop 3 along the lake/creek. Seems our unusual heavy August rain caused a real growth spurt. It's a tough long section to maintain and trim back. One suggestion might be to go against the flow (clockwise) of traffic at the start of loop 3, and get back on track (counterclockwise) at loop 4. Kinda of like when that section is flooded. Just watch for head on traffic! And Yield!!!

Review: I would call Knob Hills "one of the hardest easy trails in DFW", because it's a deceptively hard trail if you attempt all 13 miles. While it may not have gnarly climbs and descents, it has a lot of unique qualities that make it harder than it seems. First off, it's an "out-and-back" style trail, so you can only bail out at the halfway point. Second, its right on the edge of a big creek, so the humidity can make you feel much hotter than it actually is. Third, the terrain is very soft dirt or gravel for most of the trail, and it can really make it hard to keep your speed up. The real challenge of this trail is having the stamina to do the entire thing, and keeping a smooth pace that doesn't gas you out halfway. As you start from the main trailhead, the loops are numbered 1-6, and at the turn around point, they count back from 6 to 1 (but you ride different terrain on the way back). Loops 1-3 are very flat, which can fool you into thinking the rest of the trail will be easy. Loop 4 has a lot of short rollings climbs and descents that can wear you out very quickly (think EKG at River Legacy). At this point you can continue onto loop 6 which has the most challenging climbs (and therefore, you'll ride the entire trail), or if you're tired, you can choose to turn around after loop 4, but you've still got another five (demanding) miles back to the trailhead. Another thing that makes this trail hard is that most of the rollers in loop 4 have sharp turns built into them at the bottoms, and therefore you can't really use your momentum to keep yourself going like you could at Northshore (for example), because you're always trying not to go over a ledge. The toughest parts of the trail are loops 4 and 6 (eastbound) and then loops 6, 4, and 1 going back (westbound). I'd like this trail more if it had more downhill flow and opportunity to go fast, but personally, i'd rather ride it's neighbors Northshore and Horseshoe because I just feel they are more fun.

Similar Trail: River Legacy is similar in most parts.

Review: This trail is 13.1 miles long of amazing singletrack. Out of the trails in dfw, this one is my favorite. It starts off hilly, then gets flat for a while, and then it get technical and rocky. Some sections come out on the plains and have some fun berms. It's definitely has some technical descents in some sections but beginners will enjoy this trail as well.

Review: Wow, has Knob Hill matured... in a very good way. I used to ride Knob Hill long before there was parking lot, before anyone knew it was there, and back when you had to watch for loose cattle. Yup, back then many of us still rode rigid bikes (no front or rear suspension!). Heck, back then, most front suspension forks were crap and were easy to snap off on a trail like Knob Hill. It was a two way trail, and yes, riding down Goat Killer was a real hair raiser launching off the rock ledge, with no suspension no less!. Good times. But Knob Hill has evolved into a really nicely laid out ride. Those that have laid out its current route have maintained the nice sweeping flow Knob Hill has always been known for. The intermediate techy sections are still there, as well as several new ones. The addition of the roller coaster sections is fun and fast. Some of the longer, rocky ascending grinds have been replaced by more numerous, short grunts. And what a nice job finding some interesting scenery along the way. I personally like the little bluff section at the far end. This is really a trail for everyone. Yes, beginners will need to bail more than others, but that's a part of building skills. But there are enough miles for any level of rider to enjoys this trail. GREAT JOB DORBA!

Review: Man this trail has changed. Rode here for the first time in 2014 after not riding here since 1999..... WOW... pretty fun place to ride.

Review: This trail has really changed this year after the flood days. About 12 miles of every terrain you can imagine. Good climbs, wide open spaces, technical feature mixed throughout. Variety is the Spice of Life! Great job people!

Review: I figured out give an updated review of this trail since alot has changed since it was first added. Total trail length is now about 12 miles and you'll be riding through 3 different types of terrain. The first 1/3 is one way single track through some twisty woods with some fun rollers. The second 1/3 is thru flat plains which is two way so be aware of incoming riders. The final 1/3 switches back to 1 way and has you doing some climbing over loose rocks, similar to Sansom Park.

Once you loop back, it's a lil more climbing back to the flat part then finally some more climbs through the woody part, including some rooty ones.

It's much more challenging now so if you haven't ridden this trail in a while, give it a try!

Similar Trail: Marion Sansom Park on the climbs, River Legacy on the flat stuff

Review: This is an excellent trail in the DFW metroplex. If you do the full 12mi there is about 500ft of climbing with the vast majority being flat and meandering single track. The far East side has some great limestone features and the area along Denton Creek on the West side has some excellent little hills and climbing features. I suggest parking at the 377 trailhead (West side) although parking at the Cross Timbers trailhead is not bad either. This would be a good trail to bring your wife or girlfriend, and they wouldn't get too mad at you.

Similar Trail: Similar to Dinosaur Valley mixed with River Legacy
