Is there primitive camping around that we could take our 19ft travel trailer to?

You need to reserve at least 6 months in advance for Summer camping. Silver Falls state park is one of the most popular.

Yes there is.

Yeah there's is you have to a reservation though

There are rv sites with water and elec hookups.

I honestly have no idea. The hike that I went on was a rush hike sadly. But I plan on going back.
