Siouxon. It rhymes with Tucson. Despite being tricky to pronounce it's a unique, beautiful and interesting place. Located in southwest Washington state, it gets kind of overlooked because of all the other beautiful attractions near by. The area has a 7.8 mile out and back trail running along Siouxon creek. The trail passes some nice waterfalls, some of them spilling into deep, emerald green pools. It's a great place to visit on a hot summer day. You can take photos in the early morning and when your done the pools are nice for swimming!
