Highlight: Coney Creek Road (aka Coney Flats)
Coney Creek Road (aka Coney Flats) is high up on that list of locally famous trails in the state. This nearly 5-mile long trail near Boulder, CO, offers one of the few water crossing opportunities near the Front Range. This long water obstacle is set against the backdrop of the Indian Peaks Wilderness, providing some phenomenal views while requiring some technical driving. Since Coney Creek is a naturally dammed-up waterway, it stays this way all season long. The rest of Coney Creek Road is a rocky off-road trail usually connected with Middle St. Vrain and run as a loop. This loop is so well known that it is considered a right of passage for many new wheelers in Colorado. From the dense evergreens and panoramic views of mountains and the large water obstacle, this trail has a little of everything in the Colorado High Country.

Q: Hi J&J, I'm fairly familiar with this trail from mountain biking, but I also know very well that things behind the wheel can be quite different than from behind the bars. I'm a beginner and am not ready for the rock garden, but my recollection is that from Beaver Res. to the flats is not nearly as technical. (When the gate opens) what would you give the rating of that eastern section? Thanks!

Q: The info section lists the best direction to travel as West, every time I've ran Coney we came from MSV and traveled East, is that not the standard route?

Mapping Crew - Colorado

Jen & JD moved to Colorado from Chicago in May of 2015 for work and brought with them a 2001 stock Jeep Wrangler that had been garage bound for two years. Within a month of arrival, all rusty 170,000 miles of it was shaking on Colorado trails and they've never stopped. As time as gone on, their 2001 TJ had to be traded and a 2015 Jeep JK has been added to the family. JD works as a Systems Engineer for a cable company and Jen runs a business from their home during the week to pay the bills. When the weekend hits, they're almost always hitting the trail. When Sunday night rolls around, the question turns to, 'so what's next week?!'.
