Stay near home. Saguaro National Park, Reddington Pass to Manning Camp to Miller Creek. Good for 3-4 days.
Or the Chiricahuas, Rustler Park to Anita Park. Basecamp and dayhike to a few of the stunning overlooks.
Or if insist on driving, Durango. Take the train to Needleton, hike into Chicago Basin, basecamp and bag a couple 14'ers.
Listed in order of increasing difficulty. I don't know how capable your girls are as backpackers, but if they are active, involved for example in youth soccer, these should all be within reach.
