University Falls is a short easy hike to a fairly substantial waterfall that is tucked away in Tillamook State Forest. Although the falls flows year round, the flow is best in the winter or after a substantial rain.
The dirt road to the falls is very tame as far as forest service roads go. I really don't think a standard passenger car should have any issue reaching the falls as long as they drive carefully, even if the road is wet. But with that said, use caution- I didn't encounter any other cars on my trip to the falls and I wouldn't want anyone to get stranded.
From the roadside pullout, head north along the signed trail sign that points the way to University Falls. The trail will gradually head uphill and pass two 4x4 roads as it works its way through the trees. Soon the trail will begin to gradually curve northwest and you will begin loosing elevation as you work your way under power lines that run through the forest (just don't look up and you will still feel like you're in the wilderness).
The trail quickly reaches a flat area just above the river where you are presented with several other signed trails. Here you will turn generally east and follow the only trail that doesn't seem to immediately drop to the river. You will go over a small log bridge and round the corner to find the base of University Falls. Enjoy the mist from the falls (if the flow is good) then head back the way you came or explore the surrounding trails.
