Trout Fishing near Salt Lake City in late July

In late July, a friend and I would like to do some trout fishing after a
conference to be held in Salt Lake City. We are ready to travel 3-5 hours
from Salt Lake and spend several days at our destination. Would enjoy some
productive trout streams and would like to avoid crowds and very technical
fishing. Would like to wade the streams, not have to make a float trip, and
desire to keep expenses to a minimum. Skill level is beginning to
intermediate. There are a wide range of productive areas in Southern Idaho,
Southwestern Wyoming and Northern Utah and would appreciate any suggestions.
Thank you in advance for your help.
