Info from Derith
I also looked at satellite views to try to find the trail to the bridge, before I went last February, never found it. We had a great flight though with Coos Aviation over Arago. NOT expensive. 800-216-2652 He took us over Arago, Umpqua and Coquille. The land view from the pullout is pretty good, as long as you go down the trail. Enjoy your trip!
