You can make Rapid City to Custer in about 1.25 hours, but the people who love this drive never do it in one straight shot. At around 45 miles on US-16 and the Wildlife Loop Road, it is short enough to start after breakfast and long enough to earn a night somewhere memorable where the wildlife is.

Aim to clear Rapid City before the morning rush, or after it, never in it. Fill the tank on the edge of town where prices usually drop, set the playlist, and settle in for the first 25 miles to Keystone.
The headline stop on this route is Wildlife Loop Road bison herds. Leave real time for it; it sets the tone for the whole trip.
Keystone, the last stretch
Keystone sits about 25 miles in. It is the natural place to stop for the night: hotels are plentiful, rates beat the big-city ends of the route, and you wake up with the hardest miles already behind you.
Nearby, Begging burros is worth the short detour if the day is going well.
Rolling into Custer
The final 20 miles always go faster than you expect. Save a little energy for Needles Highway; it is a fitting finish.
By the end you will have seen Wildlife Loop Road bison herds, Begging burros and Needles Highway, and you will understand why this corridor is a classic.
When to go and how to pace it
One night is the sweet spot. Custer or Keystone, SD is where most people stay, so book ahead on summer weekends.
