It’s 10:37 now, so head to Western Spirit: Scottsdale’s Museum of the West for its planned 11:00 visit. It’s in Old Town, and 90 minutes is a good amount of time for the Western art and history exhibits; check today’s hours and admission before setting out, as schedules can change. Afterward, walk a few minutes to Diego Pops for lunch around 12:45. Budget about $15–30 per person, and expect a lively, casual spot—handy if you’re ready for tacos and a break from the heat.
Spend about an hour wandering Old Town Scottsdale: browse the galleries and shops around Main Street and Fifth Avenue, and keep water handy—the September afternoon sun is still strong. Then walk north to Scottsdale Waterfront for an easy canal-side stroll and a look at the public art; allow roughly 45 minutes. Finish back in Old Town at Sugar Bowl, the longtime soda fountain, for ice cream or a float (about $5–15). The Old Town stops are close enough to link on foot, though a short rideshare can be welcome if the heat catches up with you.
