We had hiked all of the trails from the Red Town trailhead over the years on Cougar Mtn., but had not done the Coal Creek Trail that heads west across the road from the parking area. It turned out to be an interesting hike on City of Bellevue trails. From the trailhead on Lakemont Blvd. SE we headed a short distance down to where the trail is next to Coal Creek and one of the old coal mine shafts. This part of the trail is on the old railroad grade where coal trains ran. There is a scenic trail that crosses the creek on a new bridge and loops back to the main trail. A little farther on we came to North Fork Falls, which is roaring at this time. Further on is a smaller waterfall on Coal Creek. When the trail reaches a side creek where the railroad once crossed on a bridge (the train bridge is long gone) the trail leaves the railroad grade, goes up a set of wooden steps and comes out on a gravel service road. We followed the road down, then up a hill back to the trail on the railroad grade. When we reached the junction with the Primrose Trail (Primrose was the name of the most northerly coal deposit seam in the area, 8'-6" thick) we followed it as it switchbacks downhill to the south side of Coal Creek. The City of Bellevue Parks Dept. has done a lot of work to rebuild this trail. New turnpikes, wooden steps and several new wooden truss bridges have been built. The longer truss bridge across Coal Creek was built in 2013, while the other truss bridges went in in 2014. The heavy timbers were brought in via a zip line system. After the first crossing of Coal Creek on this trail is another waterfall coming down from a side creek. We found a good lunch spot along the creek and had the place to ourselves. After eating we continued on the Primrose Trail, recrossed Coal Creek on another new wooden truss bridge, then started uphill to meet the main Coal Creek Trail. This part of the main trail has some ups and downs with some very muddy areas as it heads down to Coal Creek once again. One more new wooden truss bridge over Coal Creek, then up hill on some muddy switchbacks, along a hillside, then down a set of new wooden steps to where the trail is along the side of Coal Creek again. The trail is fairly flat the rest of the way to Coal Creek Parkway SE.
We then turned around and headed to Red Town. On the way back we took the main Coal Creek Trail at the junction with the Primrose Trail. It switchbacked uphill, then leveled out, then up another hill to a gravel service road. We hiked up the road a short distance then headed east on the regular trail to the other junction with the Primrose Trail. We continued on the Coal Creek Trail to complete our hike. It was nice to hike a trail we hade not done in the past. You can explore some railroad and coal mine history along the way. Met a few other hikers, dog walkers and trail runners on this hike. It is about 6 miles round trip.
For some history of the Coal Creek Trail and Cougar Mtn. from the coal mining days, see the book, "The Coals of Newcastle, A Hundred Years of Hidden History" by Richard and Lucile McDonald. Coal was mined in this area for one hundred years. Over ten million tons of coal was mined.
