Just off OR Hwy 6, about 22 miles southwest of the junction of Hwy 6 and 26, on the south side of the highway there is a little waterfall and a pool set back into the high hills along the highway. A large fallen log crosses the pool, and two large stumps stand on either side of the pool. It is not easily seen from the road, and therefore it's usually quite private and available for glamour photography.
I found these falls about 10 years ago, when my wife and I were regularly traveling to Tillamook for personal reasons. One day, on a trip back from the coast, we just happened to pull over into the large flat area along the highway and wandered back to find the falls. Since that day, I've used these falls to shoot various glamour and fantasy scenarios.
It's a dark, cool place, so you I have to shoot there during the middle of the day, when enough sunlight streams through the surrounding forest to light the area such that reasonable ISO settings can be used. And, because it's cool, it's best to shoot there during the warmest summer days, as the models can get cold quite quickly given the temperature of the water and the way the mist from the waterfall is trapped by the surrounding trees. Still, it is a beautiful place to shoot and one of my favorite locations.
I suspect I'll be shooting there for many more years to come, and if anyone else would like to use it, I'm sure you can find it from the directions I've provided about. So far, my models have loved shooting there, and it's always a fun place to shoot with lots of opportunities to experiment with light, water, and mist.
