The Red Trail at Fort Custer Recreation Area is BIDIRECTIONAL. Ride COUNTERCLOCKWISE on Monday, Wednesday, Friday, and Sunday (ascending marker numbers). CLOCKWISE on Tuesday, Thursday and Saturday (descending marker numbers).
Bikes are allowed on the Red Loop, Green Loop, Yellow Loop and Blue Loop only. Stay off the horse trails. All trails are directional. The park closes trail access at 10:00 pm. The trails DO pass through hunting land, so wear blaze orange in season.
Most riders start at the mountain bike trailhead parking lot. The trail is well signed. Red Trail features many stretches of beginner / intermediate singletrack, with some sections of more advanced technical sections. Honestly, it's a very fun trail even if you dismount and walk the few features above your skill level. To skip the most advanced section, take the "Easy" bypass around "Granny's Garden" at marker #6. Beware of the various trail crossing with horse trails and two tracks. The trail leads directly back to the parking lot.
Trail runners and hikers also use this trail. They are encouraged to travel opposite the biking direction.
The Red Trail features a good mix of meadow and wooded trails and uses many of the landscape features left from the military base, such as "The Trenches" section at the very start. If the trail has seen a lot of rain, it will be very apparent in the first mile or so of the trail.
The trail is maintained by Southwest Michigan Mountain Bike Association, please direct any issues with the trail to them via their website at swmmba.com
