Are there any hot springs on the Oregon Coast, near Newport?

Looking for some that may also have yurts

You might want to check out Trails.com to see what they have information on. You can get a 14-day trial membership for free; as long as you cancel before the 14 days are over, you don't owe anything.

I have never heard of any hot springs at or near the Oregon
coast. I know of Warm Springs, Oregon on the indian res.
And there's Bagby Hot Springs also in the mountains near
Detroit dam. And there's one other but I can't remember the
name of it but I went there as a child, and they had a big
swimming pool. It seems it was more in the Salem area
south of Portland. Whenever I've seen hot springs they are never in a ocean/sandy location. And there are lots of camping areas that have yurts, in forested areas,
but I haven't heard of any camping areas with them at the
coast. Try googling the area you're interested in, and check
for accomodations at camping sites. Maybe that will give you more in detail info. And you might try a AAA office and talk to
them about finding the accomodations you're looking for.
They have pamphlets and maps you can get for finding out
about locations in the state for camping in a yurt.
