Lost's map is an excellent guide for your question.

With a car, however, just stay in a nice hotel in Scottsdale. The road system is very good in the valley, and the only places circled above that are a longish drive from someplace in Scottsdale would be the White Tanks out in the West Valley.

Plus if you pick a hotel on the Camelback Greenway, you can do some lovely biking or flat hiking along the length of Scottsdale, along the canals, through the Scottsdale lakes, etc.

For example, you can choose a hotel such as the Hyatt Gainey Ranch, and use their bikes to ride down the Greenway to Camelback Mountain, hike to the summit and down, eat lunch in Old Town, and ride your bike back to the hotel. The ride will take you past the lakes, through golf courses, along a canal, and through Old Town.
