I took my 2 kids here yesterday. Winter wrens and Swainson's thrushes serenaded us as we started our hike in the late morning. We appreciated the shiny new trailhead for Beaver Lake, as well as the spiffy, clean outhouse.
The trail dips slightly then follows an old railroad grade along the Sauk River. It's shady and brushy at this time of year. The greenery is so lush sometimes we felt we were walking in a tunnel.
Birds sang in the tall maples and evergreens (wish I were better at identifying their songs by ear), and butterflies flitted about the flowers. We saw a little snake, a snail, and several slugs. Unfortunately, the horseflies and mosquitoes were already out, too. Plants in bloom included youth-on-age, buttercup, bleeding heart, bunchberry, salmonberry (lots of ripe berries!) and American speedwell.
It was humid and hot and a bit uncomfortable. Despite the heat, we made good time to the beaver pond. We were going to stop there for a snack, but there wasn't a good spot to sit, so we continued on a few more minutes to the end of the trail and the riverbank. That last section of trail travels through some old growth trees, and there is abundant moss hanging from branches. We heard frogs and saw woodpeckers in this section. No luck on the beaver, though.
The trail ends where a large washout dumped the tread into the river. We enjoyed our lunch there, and so did another couple with their dog. They were the only other ones on the trail with us. We had no problems with the washout before the beaver pond; I found out after we got home that the rusty metal we could see sticking out of the bank were old railroad tracks. There was just a bit of mud, but we enjoyed the multiple stream crossings with their gurgling sounds. We did need to be careful of stinging nettles, as some were hanging over the trail. Otherwise, it was a pleasant place to spend part of our day.
