A Weekend From LA: Vegas and Back
Two days out of LA buys exactly one road trip: Las Vegas, 270 miles and 4 to 4.5 hours each way on I-15. That is the honest ceiling. The Grand Canyon, Death Valley, and Zion all need a night in Vegas first, which this version does not have room for. If you have not done LA itself yet, do that on a separate trip, our Los Angeles guide covers it, and treat this as the road trip add-on.
Book these before you go
- Reserve a rental car at LAX before you land; weekend demand thins out the lot fast.
- Check Las Vegas hotel rates early. Friday and Saturday nights on the Strip swing wildly on price with almost no notice.
- If a specific show or restaurant matters to you in Vegas, book it before you leave LA. Walk-up availability on a weekend is unreliable.
Day 1: LA to Las Vegas
Pick up the rental car and get on the road by mid-morning at the latest; a Friday afternoon departure meets the worst of the Inland Empire traffic through the Cajon Pass. Route 66 die-hards can detour through Barstow for a stretch of the historic alignment before rejoining I-15, adding maybe 20 minutes for the novelty.
Budget the full drive as 4 to 4.5 hours, more with a gas or bathroom stop, which there will be at least one of given how little sits between Barstow and the Nevada state line. Check into your Vegas hotel, then spend the evening on the Strip. Skip trying to cram in a day trip anywhere else; you already used most of the day driving.
Day 2: Las Vegas to LA
A late morning on the Strip or a quick look at Fremont Street, then start the drive back by early afternoon. Sunday evening traffic heading into LA on I-15 is its own kind of bad, so leaving Vegas by 1 or 2pm avoids stacking a return-traffic crawl on top of an already long drive.
If you have an extra hour, the Hoover Dam viewpoint sits just off the route out of Vegas and needs no ticket or reservation for the overlook itself, only for the interior tours you will not have time for on this version.
| Day | Focus | Drive Time |
|---|---|---|
| Day 1 | LA to Las Vegas | 4-4.5h |
| Day 2 | Las Vegas to LA | 4-4.5h |
Is 2 Days Enough for Vegas and the Grand Canyon?
No. Vegas alone is a 4 to 4.5 hour drive each way, and the Grand Canyon’s West Rim adds another 2 to 2.5 hours past Vegas, one way. Fitting both into 2 days means arriving late, sleeping little, and driving in the dark both ways. See the 3 day version if the Grand Canyon matters to you.
Do I Need a Car for This Trip?
Yes. No train or bus route between LA and Las Vegas beats a 4 to 4.5 hour drive by much, and once you are in Vegas a car makes the Hoover Dam stop and any side trip actually workable instead of dependent on a tour bus schedule.
Longer versions of this same road trip add the Grand Canyon, Death Valley, and Utah’s Zion and Bryce Canyon; see the 4 day , 5 day , 6 day , and 7 day itineraries for the extended loop, or the full guide for all 7 road trips at once.
