Maintenance of the trails has declined. Some areas are prone to grow in with summer growth. Washouts have become worse. Tree fall remains on the trail longer than before. Horse traffic has increased, please yield to horses.

The trail system here does not drain well. It's best to avoid these trails when raining. It's even better to allow at least two-three days of sunshine post rain. However, when the trails are dry Blue Marsh flows fast!


A great place for beginners and experts alike. Blue Marsh is easy to navigate and enjoyable in either direction. The trails here will test your fitness and skill as it's covered with punchy climbs and quick descents.

Need to Know

There is pipeline work near the stilling basin that affects trail navigation.
Trailforks may be more up to date with routing and trail conditions.

There is a parking fee for some of the parking lots. There may not be an attendant when you drive in but use the honor box and register. The Park Office does patrol their lots year round and will ticket non payers.

Free parking at the Stilling Basin and Old Church Road lots. These are the two common mountain bike and runner lots.

I recommend beginners to park in the lot on Old Church Road. The trails on the northern border are a little more flat

Blue Marsh is a multi-use trail system so IMBA rules of the trail are in affect.


Parking at the Stilling Basin or on Old Church Road is free year round. Other areas may have a seasonal car fee.

The Stilling Basin is the most common mountain bike parking area. There is a lower lot and an upper lot. The lower lot has a portajohn. The mileage/trail markers start and finish w/ at the Stilling Basin.

Riding the loop counter-clockwise is the most common direction. Early sections of the trail cross several park access roads. Be mindful and check for vehicles prior to crossing.

The north side of the loop is some of the easiest and flattest singletrack Blue Marsh has to offer. This can be a great place for a beginner out and back. However, once you cross over to the south side you'll encounter three difficult climbs and descents in short succession.

The descents are expert level in steepness and obstacles. Most of this route is singletrack but like the rest of Blue Marsh there is some farm field and abandoned pavement. The trail is well marked with mileage markers and hiking trail placards.

The largest climb on the south side is in close proximity to the now closed Blue Marsh Ski area.

Stick to following the trail markers and you can't really go wrong. The trail markers even have a mileage count for you.

Be wary of the descents as heavy rains can create washouts, loose rock, and exposed roots.

Follow the white arrows when encountering any paved road (abandoned or active).

"Main Hiking Trail" is the same as the Lake Border Trail. "Fox Trot Trail" will take you back to the Lake Border Trail. "Day Use Area" is the same as the Beach/Picnic/Snack Bar area.

Shortly after entering the trail from Old Church you'll head into this "cave" of trees via the singletrack.
