Highlight: Middle St. Vrain
This trail near Boulder, CO is popular to combine with the Coney Creek (aka Coney Flats) Trail, this part of that loop is considerably easier with the exception of The Gatekeeper. Middle St. Vrain is located near the Indian Peaks Wilderness which offers some great views and great forest scenery. The drive itself is a nice combination of off-road bumpiness and a trip through the northern Colorado wilderness. There are a number of official walking trails and fishing opportunities available and many people camp nearby just for the chance to walk these trails. Water runs as a year-round stream through many sections of the trail and you'll drive over Timberline Falls. Middle Saint Vrain may not have the water crossing of its neighbors, but it is a great trail onto itself and a Colorado favorite.

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?!'.
