I'll be in northeatern Utah in May and would like to canoe/float/drift the
Green River.
Can someone suggest a scenic, fast, flat-water reach of 20-25 miles that is
doable in one day?

I'd consider (a) something two of us can do in an open canoe, max of class
II, (b) a
guided/unguided canoe group, or (c)a commercial rubber-raft guided trip.

Are there other options? Anything I'm missing?
I will also need ferry service.

TIA
