We did this hike on a HOT Sunday, over 90 degrees, so the shade was much appreciated. Contrary to the description in Romano's Day Hike book, this trail was not very much along the creek except right in the middle. It starts out in the campground, which was pretty full the day we went. Despite this, we had the entire trail to ourselves – not another (human) soul did we encounter.
After leaving the campground loop, the trail crosses Big Creek on a very nice bridge, where you can go right or left. We did the loop clockwise, following the creek for just a big before heading uphill and leaving the water below. There were tons of benches and small bridges crossing what are apparently streamlets in wetter months. This entire trail is a paragon of thorough construction and maintenance – whoever worked this trail sets a goldmark standard! The smallest streamlet crossings (as in, maybe 2 feet wide) are crossed by sturdy little bridges. There is drainage throughout and tread wide enough for two nearly the whole way.
At about 1 ¾ miles, there's a well-signed trail to a confluence of Big and Branch Creeks. Take it; this is the nicest bit of the hike, with lots of lovely rocks to sit on and watch the water tumbling by, peek-a-boo views of Mt. Washington one way and Ellinor the other, and delicious, cool water. It was so hot out even under the shade of the trees that my cotton shirt dried in less than an hour after dunking it in the creek. There are also little log bridges here, and good pools for kids to splash and wade in. After this little respite, the main trail continues by the water only for a short time before heading back along a hillside with a road (concealed from sight but not sound by trees, but not very busy) to the uphill side, perhaps the road to Ellinor trailhead? There are a couple other creeks to cross (again, on amazing bridges). Be sure to check out the sign at one of them (No Name? Maybe Skinwood, can't remember). You are not alone on this bridge after all!!! (kids especially will enjoy this surprise)
Returning to the woods and huckleberry bushes, the trail heads back downhill to the creek, the bridge, and the campground. There were lots of red huckleberries along the way, and the number and size of them attested to how little used this trail is. I think this would be a wonderful hike for a rainy day and/or at a time that all those little bridges actually have some water under them. It would be a great hike for kids or if you're staying in the area and want a nice, easy hike. Total 5 miles including the trail to the confluence. Gain 900 feet according to Day Hikes book. Note there were lots of deer flies, some horseflies, and lots of mosquitoes who were on us like, well, flies every time we stopped EXCEPT by the water, where a breeze seemed to keep them away.
