This trail passes through mature second growth and affords the hiker an excellent walk in the forest. Upper Big Creek Loop Trail #827.1 makes a four mile loop around Big Creek Basin. To access the trail, start at the picnic shelter, cross the lower Big Creek Bridge and then turn left. The trail proceeds in a northerly direction for 1.7 miles to a bridge across Branch Creek. Near this point a side loop trail goes to the confluence of Big and Branch Creeks. From Branch Creek, Mt. Ellinor Connector Trail #827.2 connects the Loop trail to the Lower Mt. Ellinor trail in 1.3 miles. The Loop trail runs northeasterly 400 to the Big Creek Bridge then continues, crossing several creeks, until the campground is reentered at 4.0 miles. Each creek crossing and confluence are excellent places to enjoy lunch (benches provided) in beautiful surroundings.
