The Blue Creek Trail #620 descends through a diverse mixture of vegetation from its upper trailhead to the lower trailhead near the confluence of Massey Branch and Blue Creek. In the upper sections of the trail, it travels through aspen and spruce/fir stands and gradually transitions into Gambel Oak, Ponderosa Pine, Douglas Fir, Pinyon Pine and Utah Juniper, and Narrowleaf Cottonwood as the trail descends.
The Blue Creek drainage has numerous beaver ponds along its entire length and supports a large number of trout. Along the creek, there is a great diversity of plants and shrubs as well: Dogwood, Serviceberry, Chokecherry, Hawthorn, Mountain Ash, Wolfberry, Alder, Mountain Mahogany, and Willow. The trail offers many scenic vistas and opportunities for viewing wildlife as well.
Most of the trail is fairly smooth and non-technical, but there are a few rock gardens interspersed. Most of the difficulty of the trail results from thick overgrowth that creates surprises around every turn. This trail is frequented by the local bear population as well based on the amount of scat along the entire length.
