Mountain Biking St. Mary's River Park

****   Add a review
#27 of 99 mountain bike trails in Maryland
#2,077 in the world

I rode the trail starting from the bathrooms, the trail ended back at the parking lot behind the playground. A few things if note, it cost me three dollars to park my car in the lot (honor system) so bring cash, and I heard that the trail is only open March through November. Don't know if that is true. The trail is a multi-use trail, but is clearly built for Mountain bikers. The area has a quite few creek/stream crossings some were fun to bike/jump across others I was more comfortable walking. Most of the trail is smooth fast rolling single-track with few rocks, but lots of roots. This would be a great trail for beginners to push themselves to the intermediate level because of some quick, but technical climbs and descents and a good place for an intermediate biker to have alot of fun and go fast. There are definetly some advanced moves out there to do though to with some technical stream crossings on 2" X 12" boards and a fun log pile to 12' plank balancing beam (located about half of the way through the trail. The white blazes are the main trail but anytime the trail forks it seemed to fork into a more technical route which was more fun and then looped back to the main track. If any locals have better info please add. Will definetly be back.

Getting there
How to get there: Head North on Route 5 from Lexington Park or South on Rt. 5 from D.C. Exit at Camp Cosoma Rd and follow signs to St. Mary's Park. Once in the park, drive to the far side and park by the bathrooms. A sign marks the trail to the right. I snagged directions from another site just to make sure they were accurate.

    I just discovered the Pine trail. It has some flow and a couple of tight turns and a few jumps. To do it properly, it's best to start on the north end and go south; you'll be going mostly downhill then and hit the small jumps better. For the whole trail, hard tails will work but I think that short to medium travel full suspension trail bike would be best. This park has fast pedaling parts with sections that are quite rooty. I like it. Great work out.

    I was back in the area for a retirement ceremony and decided to ride the trail for old time's sake. Just as good, but somewhat easier than I remember. Great for a workout. Missed the many, many rides there!

    Some technical riding but not much. The trail winds around a watershed through beautiful groves of hardwood trees. This time of year you will find very beautiful scenery to enjoy as you cruise through some of the slower areas of the trial. The wife and I really enjoyed the ride and plan to go back. Be careful riding in the fall, heavy leaf cover on the trail can make it a bit slippery.

    Great track for intermediate riders, my cycling all told me the route that I took was 7.2 miles but it feels long so don't expect too short of a ride. Lots of roots and some puddles and muddy spots so make sure to go on a dry day. Well used path so it nice and wide with not too many shrubs in the way. Hardest part of the trail is right in the middle so its a nice progression. Costs 3$ to get in (honor system). Not too many people on the trail on a Saturday at ~12:00.

    pretty good trail! there are a lot of exposed roots so be ready for the bumps! there are some good speed spots now and then. the bridges arent too wide and the trails can be kind of tight too.

    I have to say this trail is sweet! I have been to a few trails in the area I this is my 2nd favorite trail! This trail has a lot to throw at you with it being roots, skinny bridges over creeks to tight trails. I had a blast, I got there around 6:30 and got on the trail and it started to get dark. Once I got to the open part of the trail it was getting pretty dark and had a hard time seeing the last mile of the trail. Fun stuff though. Had a blast going again real soon.

    Decided to make the drive from Upper Marlboro and try this track out.... it was highly disappointing in my opinion. There are way to many exposed roots on the trail even though it is wide and clearly marked. A full suspension bike would probably have no problem, and no complaints but on a hard tail its a bit of a pain. Gear selection is key. Mostly uphill it seems. Track took 48min to complete 7.48 miles, I'm a beginner though. * Review edited 4/7/2012

    Nice loop, all singletrack except for 1/2 mile over the dam. Stay's fairly close to the lake the whole way, a few technical sections, 1 fairly difficult creek crossing. I did this 4 times last year, look forward to many more this year..

    The trail was good fun. The directions are good; however, my Garmin sent me to a different "St. Mary's River Park". It wasn't far away, but the MTB trail is actually "St. Mary's Lake Loop Trail." The trail is quite wide, mostly level, packed sand with the typical east coast exposed roots. I thought it was mostly a beginner-level trail with bits of intermediate sprinkled here and there. Overall, it was fast with good flow...there is some sand, so watch the turns. It would be a great trail to get folks introduced to mountain biking. Good for families.

    This trail is fairly difficult. Steep inclines and steep drops. 20" trail. I live real close so this is my favorite trail. Great wildlife. Plus this trail is not at all crowded. In the fall the tail is covered in colors and the snow riding is great.

    This trail is fun, there are many deviations, some tangent off into private property/dead ends and some re-connect with the main loop. Does not get very muddy, even the day after a storm there does not seem to be much muddy spots. There are alot of roots and stream crossings, many have little bridges though. The downhills can get fast, watchout for the occasional sand spots on corners. This loop has not got old yet and definately keeps my interest. It is a 7.5 mile loop that starts/stops at the main parking lot.* Review edited 9/16/2007
