Mianus River Maze is a fitting name for this ride as it travels through the warren of trails that run through Mianus River Park. This gives riders a great deal of variety to modify this loop to taste or the day's schedule. This quintessential Connecticut park is very scenic and offers wide carriage trails, rolling hills full of boulders and roots, log jumps, drop-offs, and steep technical sections.

Need to Know

  • The park has two parking lots, one on the Stamford side and one on the Greenwich side. You can start this ride from either one, jumping on at any of the three available yellow trailheads. Both of the parking lots are far off the main roads, so use your GPS.
  • While this ride primarily follows the Yellow Loop, it can get very confusing. Each section of the yellow loop has its own trail names, so you have to be mindful of both the name and the blaze lest you end up completely off the ride.
  • Be aware that the carriage roads are very popular with other users. Once you move on to the singletrack, the crowd thins out significantly.


Starting from the Greenwich parking lot, the ride begins on the Main Road. This is not your traditional flat wide road, it is hilly and full of rocks and roots. When you reach your first junction point, turn left off of the Main Road on to the Oak Trail. This trail is full of interesting obstacles, many in tight succession creating a nice trials-like course. There are large boulders and rock faces, as well as many rocks, roots and logs. You won't get bored here.

This continues on to the Second Loop Trail where you'll find technical climbs and descents. Veer off the Second Loop Trail briefly to spin around the purple-blazed Poplar Trail which loops back to the Second Loop Trail.

You'll meet back up with the carriage road for a ride along the Mianus River. Its features are very similar to the earlier carriage road. It will end at the main entrance on the Stamford side. You'll take a short ride to your left on Merriebrook Lane. Before you cross the bridge, the yellow trailhead will be on your right for the start of the Riverwalk Trail. There are some very challenging rock steps to climb and descend at the start. After that, you are back to boulders, rocks, roots and technical climbs and descents. This will continue through the Indian Rock Trail and the Laurel Trail.

You finish up the singletrack portion of the ride on the Swamp Trail, which has some tight technical switchbacks and complex sequential obstacles. The trail meets back up with the Main Road, which leads back to the parking lot.

History & Background

Fun park and friendly people. I did go off trail a few times, which my rating reflects. It's easy to go off-trail, it's hard to get lost. 9mi — 1h 30m
