St. Vrain River Trail

Explore the St. Vrain Greenway and Sandstone Ranch Loop, a moderate hiking route spanning 5.0 miles (8.0 km) with a gentle elevation gain of 141 feet (43 metres). This trail offers a pleasant journey through diverse scenery, largely following the St. Vrain Creek and winding through various city parks. You can expect to complete this loop in about 2 hours and 3 minutes, enjoying the mix of paved and natural surfaces.

When planning your visit, remember that while the St. Vrain Greenway itself is open 24 hours, the trailheads and surrounding lands typically operate from one hour before sunrise to one hour after sunset. It is a good idea to check for current trail status before you go, as some sections were affected by past flooding and might have detours or closures. Also, be aware that dog restrictions apply in certain areas east of County Line Road to protect local wildlife.

As you hike, keep an eye out for views of the majestic Front Range mountains, with Longs Peak often visible in the distance. Within the Sandstone Ranch Nature Area, you will discover peaceful ponds, groves of vibrant cottonwood trees, and a short spur trail leading to an overlook that provides expansive vistas. This route offers a unique blend of natural beauty and accessible urban green space.
