Recommendations for 1-3 night trips in eastern Oregon?

Anyone have any recommendations for a place I could visit east from Bend for 1-2 nights? Just looking to explore the state some more, maybe do some light hiking, and hopefully keep working on my photography as well. Quiet with some conveniences.

I fell in love with the Alvord and Malheur area last year and am already planning on spending a week out there in May. I’ve been to Painted Hills a few times too. Looking for something else to add to the list before the summer rush, preferably where I can rent a place since I'll have the dog with me, though I'm not opposed to camping if that's the only option either.

Thanks. I know its not strictly Bend related, but there's not a lot of location specific subs east of here and you've all steered me right so far ;)
