Water, water everywhere and quite a drop it takes! Cougar Mountain's Coal Creek Falls is the primary attraction here, but it's the water underfoot that really makes the area special. Such abundance helps keep the forest green and fragrant, with wildflowers in season--and abundant summer mosquitoes. Come in November through May, when the nights are too cold for these pesky biters and the falls are full of runoff. In the spring you'll find skunk cabbage, and through the early summer you'll enjoy plump, juicy salmonberries. And at the end, you'll enjoy the cool cascade of Coal Creek Falls.

From the trailhead, head up toward Red Town. The route you want veers left onto Cave Hole Trail. Once upon a time, mules pulled wagonloads of coal down this trace, and later, as the coal veins played out, folks used it as an access route to another easily accessible fuel source: firewood. Today's trail uses that same old track.

As you climb away from the old Red Town site, you'll notice areas where the ground seems to have slumped in on itself--these are the cave holes that give the trail its name. The holes formed when miners pushed their underground extractions too close to the surface, leaving a void that eventually caved in, creating a "cave hole" in the ground above.

Less than 1 mile after leaving the trailhead, you'll find the Coal Creek Falls Trail leading off to the right. The path meanders around the upper slopes of Curious Valley before slanting down into a small gulch carved by the tumbling waters of Coal Creek. Here, about 1.25 miles out, you'll find the falls.

Coal Creek Falls can be spectacular during the rainy season of January-March, thundering down the rocky chute. Venture out during a particularly cold spell and you'll find marvelous ice sculptures formed by the splashing and spray from the falls. By midsummer, the falls usually shrinks to nothing more than a small splattering of dribbling streams between the rocks.
Driving Directions:

From I-90 take exit 13 onto Lakemont Boulevard. Drive south on Lakemont Boulevard, which becomes Newcastle-Coal Creek Road. After crossing "The Pass" and starting down, cross Coal Creek and find the trailhead on the east side of the road at a sharp bend in Newcastle-Coal Creek Road.

Steph was in Portland and BC only had half a day of school, so I picked him up and we headed to Cougar Mountain Park. It’s a nice little patch of ground considering how close it is to a major urban area. We decided we wanted to see Coal Creek Falls.

The parking lot was fairly empty which meant we beat the rush. Yay for us! On all of our previous jaunts, I’d worn running shoes, so my hiking boots were very happy to hit the trail.

BC wasn’t sure which way he and Steph had gone the year before, so we went the opposite way he thought. As we started up the gentle slope, flowers and wild roses started to appear.

Just before the intersection of Red Town Trail and the Quarry Trail, there is a meadow restoration in progress. BC didn’t want to see it until he caught sight of the old, rickety bridge across the stream. Oh to be eleven again! We took a quick look around and snapped some shots of the wild flowers growing in and around the meadow.

We hit the Quarry Trail and immediately saw giant rocks that formed a bit of a natural bridge. BC, being 11, was intent on exploring. But the curmudgeon in me was worried about weather and time, so we saved it for another day.

Soon enough the trail started to get steep. The elevation gain here is about 450 feet in half a mile. Nothing major but it’ll surprise you if you aren’t prepared. More and different flowers started to show themselves through this part of the trail, along with some horse tracks.

After a few switchbacks, the trail leveled out again and we were pretty sure we were approaching the intersection with the Coal Creek Falls Trail. We made a few left and right turns, jumped over a few banana slugs, and arrived at the next trail.

This one headed down, and we could just hear the sound of the falls. The trail passed through what I’m pretty sure at some point was a meadow, either natural or man made, I can’t say. This little spot was full of wild roses! Hundreds of them, ten feet tall, all just starting to bloom. I’ve never seen so many roses in one spot. Steph asked me later if they can be raised from a clipping. Don’t know about that…will have to ask my green thumb friend.

The trail heads down a slight slope and then makes a right along a steep slope. From here you can see Coal Creek. A few hundred feet further takes you to the falls.

The falls are thirty or forty feet high with another four or five foot drop at the bottom. The base is easily and apparently frequently accessed from the trail. There is also an unofficial trail along the left side of the falls. That one looks a little unsafe for kids, though BC said he saw kids on it the last time he was here. We scrambled over some logs and rocks to the base and took a few pictures. Then it was time to head for the car.

In all, we spent a hour and a half hiking two and a half miles on a trail less than ten miles from downtown Bellevue on a Wednesday afternoon. We saw tons of flowers, a pretty waterfall, three dogs, and four people. Pretty sweet if you ask me!

The trailhead is easy to find with plenty of room for several cars to park. The trailhead kiosk has a trail map posted and trail maps available to take on your hike or you can print one before you leave home. Visit: http://www.kingcounty.gov/[…]/cougar.aspx

The advantages of this hike are the many options to take several different trails. Today the goal was to visit the falls. All intersections leading to the falls were well marked with trail names and distances. The trail was muddy in few spots but not a problem.

This is a wonderful family hike. The trail is wide for a majority of the time, the trail is a short one way distance of 1.25 miles and upon reaching the falls you are rewarded with a surprisingly nice close up view of the small, yet three tiered, waterfall next to a bridge providing a picturesque sight.

Snuck out of the house early for a little birthday walk. Weather was supposed to be good but by the time I arrived at the Red Town trail head it was raining pretty good. I had never done any of the hikes from this side of Cougar. I took the Cave Hole trail up to the Coal Creek Falls trail, down along the Quarry trail then back to the trail head via the Red Town trail making a nice little loop, (grab a map at the trail head and just keep turning right.)

The falls isn't super huge but still definitely worth seeing, especially when it's big in winter and spring. There is a neat boulder wall along the Quarry trail before it runs into the Red Town trail. A bunch of spring birds are out already - lots of Robins looking for breakfast and a bit annoyed I was following them down the trail. The entire walk is in the area between Cougar and Newcastle proper so it's really quiet - no road or neighborhood noise. Even though it was raining much of the way, the trail was in good condition and easily passable even for little ones. Sorry no pics since it was so wet out.

A rare sunny day in February, so I decided to explore the upper reaches of Coal Creek. I started out from Red Town trailhead, following the Red Town trail to Indian Trail, then out to Far Country Falls. Not much of a "falls" - just a series of small cataracts flowing down and around mossy rocks. From the Far Country lookout, I doubled back to the Quarry Trail, climbing up to the cutoff for Coal Creek Falls. There was still a bit of snow in the woods, though none on the trail. Spent some time photographing the falls before continuing along the Coal Creek Falls trail to connect with the Cave Hole trail, then back to the Red Town trailhead.

The trails were in generally good shape. A bit muddy in patches, and in places some water over the trail, but that's to be expected this time of year, and nowhere were either of these a problem. A few blowdowns had obviously recently been cleared.

The main purpose of my trip was to photograph Coal Creek Falls. I visited Far Country Falls first, on the off chance that it was worth a photo or two, but mainly, I was after photos of Coal Creek Falls. The falls was flowing quite vigorously, and I arrived after the sun had gone behind a hill, so there were no issues with harsh lighting.

The Quarry Trail portion of the hike was a bit strenuous (I am over 60 and have asthma), but manageable. The rest was relatively easy, and would make a nice day hike for a family.

We decided to take advantge of the "break" between weather systems and head to Coal Creek Falls for a quick hike. The forcasted partly cloudy skies remained mostly cloudy all afternoon and even squeezed out a couple of surprise hail showers for us just to make things more exciting while we were hiking.

Our route yesterday included the Cave Hole Trail to the Coal Creek Falls cutoff and a return to the Red Town Trailhead along the same route for a 2.5 mile hike. The trails were in fine shape on this date and the falls were flowing nicely. There were no blowdowns or obstacles to speak of on any of the trails we hiked yesterday. There were many other parties out taking advantage of the "break" in the weather as well.

After returning to the Red Town Trailhead, we ventured across Lakemont Boulevard for a .6 mile roundtrip hike to North Creek Falls along the Coal Creek Trail. There are no problems to speak of on this mainly downhill part of the trail. As you hike along the trail, near the large cave on your right the trail splits and you can either go straight or take a bridge across Coal Creek to your left. Either way will take you to North Creek Falls and the two trails merge into one just before arriving at the falls near another large bridge. All in all, it was a great family outing with two nice waterfalls to check out.
