Take a little side trip to Tonto Natural Bridge State park (
http://www.pr.state.az.us/Parks/TONA/index.html http://www.americansouthwest.net/arizona/tonto_natural_bridge/state_park.html), north of Payson (west-northwest of Kohl's Ranch about 15 miles). If your hiking interest/abilities are zero to moderate, go on the River Trail, but if you are able/interested in a slight challenge, the Waterfall Trail is not to be missed; the Gowan Loop Trail is worth the huffing and puffing.
Payson has a few very interesting antique shops; don't miss the one on the east side of Beeline Highway, just north of the intersection with 260.
Four or five miles east of Kohl's Ranch, at Christopher Creek, there's a trout hatchery that's open to the public.
If you're more of a behind-the-wheel sightseer, take the trip east through Show Low and south on US 60 towards Globe, through the Grand Canyon of the Salt River (
