We ended up here after 4 other hike failures due to rain and closed roads, bridges out etc. It was a flat and beautiful hike. A bit overgrown in places but at least we finally got out. There is some mud on the trail already.  

Great forest bath.

Road: Good for all vehicles.

TH: As directions say, park on the side of the road across from the hatchery. No toilets. Then walk across the bridge and just passed the gate (it was open when I was there) and you'll see an ecology block and the sign for Edfro (as depicted in my picture).

Trail: The trail is great for the first few miles. After crossing edfro creek it becomes significantly overgrown and starts to gain some elevation. It eventually ends at logging road which we took down to the river.

Unfortunately, this hike just wasn't for me. I only made it to just past Edfro Creek before turning around. A considerable amount of the trail feels narrow, overgrown, and stagnant. There are portions that feel incredibly maintained, so it was just inconsistent. The DNR portion of the trail was very overgrown for the 100 or so feet I walked. 

The trail overall is just a little muddy in spots and the water crossings all were manageable. Lots of flies, too. 

Human-wise: A Nissan Pathfinder was parked in front of the gate, hiding the foot path around the gate. Around the .8 mile mark, some guys were definitely shooting off of one of the spurs, and their off-leash dogs came up to me and my pup on the main trail. Friendly interaction but it never should've happened. The friendly duos I passed on my way out balanced it out.

Was not able to complete the whole hike today we ran into some water at about the 2 mile mark 8-20 inches deep on the trail. Still stopped and had lunch and hung out in the woods still makes it a great day.

We hiked the Edfro Creek Preserve Trail (the Thousand Puddles Trail) on a rainy Sunday, getting as far as Cavanaugh Creek, for a 6-mile round trip.

As previous reports have noted, the trail is very muddy in places and quite overgrown with trailside salmonberry bushes and stinging nettles (see photo).  The latter are quite tall and would be a problem for small children hiking the trail.  They could get hit in the face with nettles.

The streams that cross the trail are running high and the rocks and logs are very slippery, making dry crossings impossible.  Even with ankle-high waterproof boots and gators, all three of us had soakers by the end of the hike.  Hiking poles were very helpful in the crossings, but I actually fell in once in spite of using two poles.  

We were unable to find a way of crossing Cavanaugh Creek without wading knee deep in fast water (see photo), so we stopped there for lunch and then turned around.

We only met one other group on the trail, a family starting the hike just a few hundred yards from the trailhead.  We warned them about the nettles and the high water but they said they were familiar with the trail and continued on.
