Mountain Biking Rosaryville State Park

****   Add a review
#6 of 98 mountain bike trails in Maryland
#488 in the world

Trail Description: Rosaryville is an excellent mountain biking and equestrian destination with a main perimeter trail 8 miles in length. It consists of a lot of tight twisty singletrack with some short steep hills built and designed in cooperation with IMBA's trail building guru and former trail crew member Rich Edwards. There are beautiful overlooks, awesome flora and fauna, large open fields. The trails offer something for all levels, but tend toward moderate speed singletrack, with moderate climbs, and most of the trail is under the cool canopy of mature hardwoods. Some technical sections will require beginners to dismount, but intermediate riders should find most sections rideable and challenging. Trails are not crowded, but keep a close eye out for the occasional equestrian rider or hiker.

Cost for park access is $3 per Md. car and $4 per out of state vehicle. Ride in access is free so park at the nearby shopping center and ride in! Trail maps are available at the Mt. Airy mansion on the other side of the park off Rosaryville Rd. 8-4 weekdays or at the Cedarville Park complex or on the DNR web site at http://www.dnr.state.md.us/publiclands/trailguides.html

    Great Singletrack with nice hills and downhills. Good areas to jump and do tricks. Definitely going back

    These trails could be fabulous with a little bit of work. Sadly, there are many mud pits, ruts and puddles along the way which slow down an otherwise very fast ride. Some of the puddles are deep with soft mud at the bottom, some of the bridges look dangerous and some are missing completely. The trails themselves are fun to ride with lots of flow, and only some technical spots. It would be a very easy ride for beginners if they were repaired.

    This trail is in need of some love, I'd be more than happy to donate my time to maintain/ repair some spots on this trail, I feel like every time I ride here I come across a new problem spot that wasn't there a few rides ago, the inner loop was great at one time but now it's starting to need some attention. I wish this trail would get the love and maintenance that some other trails get like fountainhead or patapsco. I hope to hear about a trail work day in the future , I'll be there!

    I gave it a 4 only because the trails were not bad but not great due to all this rain we been having for the past several weeks.

    Ive already done review on Perimeter Trail you can find below. This is a review of the Inner Loop. So it is billed as more technical for those seeking that. It lives up to its billing. Lots of log piles, some trail whoops you can jump, and some drops in the 1-2 foot height range. All except for a few log piles are rideable around if you dont want to do it. I would categorize it as intermediate. This year is my 2nd year back riding since a long layoff after 90s and is the year to get into jumps and drops. This was a perfect trail to start with. Nothing epic but if you are a decent rider just starting to do jumps and drops, these will test your metal while being doable. I did every feature there on a hardtail, although some I had to session a few times to get (especially the big log piles going uphill). The drops just commit to and you can do them first time. If you dont have a dropper post drop your saddle before you start. Imo trail is designed to be ridden in the direction of the drops as it is more fun this way, although it can be ridden other direction and is def not boring. I was getting a little bored with Perimeter Trail as it is just not challenging to me anymore. If you feel the same, hit the Inner Loop.

    Ok, so I always say I'm going to write a review but I never do. Well, not today!

    This trail is exactly as advertised. Fast and flowy with short, punchy climbs (nothing long or sustained and you're quickly rewarded with a modest but fun descent). You'll need to be mindful of the occasional horse apple as this is an equestrian-friendly trail as well. I only encountered a few other riders and hikers and you can come up on them quite unexpectedly, so be mindful and keep yourself in check. The trails could do with a bit of maintenance because of a few fallen trees and some debris scattered about, but this was to be expected after 2 horrendously windy days last week. All in all this was nice trail clocking in at around 9ish miles. If you haven't given it a go yet, do so. I know I'll be back.

    Rosaryville is mostly about flow. The perimeter (outer) loop (~9 miles) has plenty of opportunity for riding at speed. If you ride clockwise, there's really only one noteworthy climb - right after a bridge crossing - which is very doable for those with decent cardio fitness. There's also a two mile "inner loop" about midway through the perimeter trail which adds variety in the form of obstacles, very narrow trails and several ledges where you can air it out. At the end of the inner loop you reconnect with the perimeter trail. Because this is a bit of a hike for me I like to do 2 or 3 laps. Just be careful of riders coming from the opposite direction especially around the blind curves. On a final note be forewarned that these trail do not drain well and should not be ridden a day or two after any meaningful rain or especially after the spring thaw.

    Went there yesterday 7/16 with my 10yo son and we had a blast. Ride the perimeter trail clockwise and we thought the first 3-3 miles was a bit harder than the rest, and the last 3-4 miles we found to be fast. Was wondering why something can't be done like clockwise only on M, W, F,Su, and counterclockwise only the other days. This in theory we oils remove the risk of blind turn collisions. Just a thought. Overall we loved it and we will be back.

    Awesome fast flowing single track roller coaster. Ride here all the time- its 5 mins from my office. Have ridden both clockwise and counter-clockwise. Counter has better downhills and is more fun overall IMO. Clockwise is more of a workout with tougher climbs. Perimeter trail is about 9 miles. Will take you 1.5 to 1.3 hours at nice pace, around an hour if you want to push it hardcore. My current PB here is 62 mins. Im 45 and intermediate and can ride whole thing with only one uphill with a root on counter clockwise run that I've never been able to get over. So hopefully that helps you get an idea of how long you will need and skill level. No need for FS- hardtail is best on this trail to get max speed out of it. Warm up those thumbs bc you will be doing a lot of shifting. Pedal every opportunity you get to get max speed and use your front top chainring a lot. I actually keep my rear deraileur in the middle of the cassette and often just switch my front deraileur for a lot of this- especially the flowy parts. Get into that top chainring just at you hit the crest and get the power on the pedals as you go over the crest. Then enjoy. A couple of granny or near granny gear climbs but short and not too bad. At the bridges get into smallest chainring up front and about middle in back just as you get to the brdige bc there will be a steep short uphill on other side. If you wait til you cross bridge to shift it will be too late and you are ... Well you know. Doing hike a bike for a few. This is a trail built for mountain biking unlike many that are converted from himing trails. That means the turns are designed for bikes, not real sharp like hiking trails. So you can really lean in and carry your momentum thru the turns. When it's dry on some turns you brake and slide around and then right back on the power- so be prepared to do some controlled slides if you want max speed. Get out of those clips! A few blind turns that are marked with signs. Be careful for oncoming traffic. And watch for horses-they can be out there. Remember it's two way. This trail is built for speed- get at it and enjoy. See you out there!!

    You can choose your direction based on personal experience or on others recommendations. One consideration is the counter clockwise will finish more elevation changes than clockwise. Although the elevation changes are overall minimal.
    I ride a 29er hard tail, and was comfortable riding this trail with the front fork locked out and spent most of my time in the big ring up front.
    Definitely a fun trail.

    Excellent, flowy single track. I generally prefer to ride the 9ish mile loop clockwise. Trails are well maintained and clearly marked. Enjoy.

    This was the perfect trail to get out on to start the season. Took advantage of global warming to go out on Feb. 25 and could not have asked for better weather, until the hail started.Overall this was the perfect trail to get warmed up with. The tight banked turns kept things interesting and the rolling hills with no steep upgrades kept me in the saddle working the whole time.

    I really enjoy riding here. Trail has great flow. The outer loop is about 9 miles but there is also a 2 mile inner loop which has quite a few log-overs and some decent launch points to get some air. There are some decent climbs that make it a good workout and plenty of opportunities for speed. Worth the 45 min drive.

    This is a great 9 mile loop close to DC. You can't get lost, since there aren't any trails that really branch off. There isn't much in the way of technical riding. Just a long, flowing roller coaster of nice singletrack. There are a couple spots where you can try your hand at some small natural drops, but there are small detours around those for those that aren't willing to give it a go. This is a great trail to go fast if you are an intermediate rider and a great learning trail if you are a beginner. Have fun.

    I consider this my home trail, I live in clinton but the trail at Costa park is horrible, this one is great, i actually started MTB on this trail doing half the loop counter clockwise, I now do the whole loop clockwise and I love every minute of it. My only knock on this place is after a storm it doesn't drain as well as some other spots so it can be a bit muddy
