The Southwest national parks loop — Grand Canyon, Zion, and Bryce Canyon from Las Vegas — is the most popular first national-park road trip in the US, and it needs a rental car. There’s no transit between the parks, the drives are the scenery, and you can do the loop in 5 to 7 days. Compare suppliers on DiscoverCars before you fly in.
Key Takeaways
- The loop from Las Vegas is about 700 miles; allow 5–7 days.
- Las Vegas (LAS) is the ideal gateway airport for all three parks.
- A standard sedan handles every paved road on the route.
- Order: Vegas → Zion → Bryce → Grand Canyon → Vegas.
- Book early – Vegas rental demand and prices spike in summer.
The Southwest Loop Route and Distances
The classic loop runs clockwise from Las Vegas. Core legs:
| Leg | Distance | Drive time |
|---|---|---|
| Las Vegas → Zion | ~165 mi | ~2 hr 45 min |
| Zion → Bryce Canyon | ~85 mi | ~1 hr 45 min |
| Bryce → Grand Canyon (South Rim) | ~150 mi | ~2 hr 45 min |
| Grand Canyon → Las Vegas | ~280 mi | ~4 hr 30 min |
This order minimizes backtracking and saves the Grand Canyon — the grand finale — for last. For each park, see our full guides: Zion, Bryce Canyon, and Grand Canyon.
Which Car Do You Need?
A standard sedan is all you need — every road on this loop is paved. The drive from Bryce to the Grand Canyon crosses high desert, so in winter check for snow at Bryce’s 8,000-ft elevation, but three seasons a year a comfortable midsize sedan is ideal and keeps fuel costs down over the 700-mile loop.
Where to Pick Up Your Rental Car
Las Vegas is the obvious base — it has the most flights, the most rental suppliers, and the most competitive prices in the region. Pick up at Harry Reid International (LAS) or a Strip-area branch. Comparing airport vs. city-branch rates on DiscoverCars often saves money, since airport surcharges can be significant in Vegas.
Tips for the Southwest Loop
- Get the America the Beautiful pass ($80) — covers all three parks.
- Fill up in Springdale and near Bryce — gas is sparse between parks.
- Reach the Grand Canyon South Rim early — parking fills by late morning.
- Carry water — desert stretches are long and hot in summer.
- Check rental rules — agencies ban unpaved roads; the loop needs none.
