Yellowstone Last Call: A Late-Summer Basecamp at Idaho Sky RV Resort

Okay, be honest. The back-to-school emails are already hitting your inbox, the pool towels are permanently damp, and somewhere in your house there’s a swimsuit that has not fully dried since June. Summer’s doing that thing where it pretends it has all the time in the world and then vanishes overnight.

So here’s your permission slip for one more trip. The big one. The one the kids will actually remember when they’re forced to write “what I did this summer” in three weeks.

Yellowstone. Late summer. Before the gates get weird and the snow shows up and you’re left saying “we’ll go next year” for the fourth year running.

And no, you don’t have to sell a kidney for an in-park lodge or fight 4,000 other minivans for a campsite by Old Faithful. You just need a good basecamp. That’s where we come in.

Quick answer: how far is Idaho Sky RV Resort from Yellowstone?

Idaho Sky RV Resort in Rexburg sits about 82 miles from Yellowstone’s West Entrance, which is roughly an hour and 40 minutes by car up US-20 through Ashton and Island Park. Call it two hours if you’re stopping for gas station snacks, which, let’s be real, you are.

That means you can sleep in an actual bed (or a cozy cabin, or your own RV) in Rexburg, roll into the park by mid-morning, do the whole geyser-and-bison thing all day, and be back for a hot tub soak by dinner. No four-hour “getting there” saga. No paying peak-season park lodging prices. Just a chill home base that happens to be a straight shot from one of the most famous places on the planet.

Why late summer is lowkey the best time to go

Everyone talks about June and July like they invented Yellowstone. But late August into September? That’s the sweet spot nobody tells you about.

The crowds start thinning as families head back to school. The bison are in rut, which sounds like a weird thing to be excited about until you see a 2,000-pound animal decide it owns the road. The elk get loud. Mornings turn crisp and golden, and the light does that thing that makes even your worst phone photos look like a postcard.

You still get warm afternoons. You still get long evenings. You just get them with about half the people and none of the “we’ve been in this traffic jam for 40 minutes and it’s a single bison” energy. (Okay, you’ll still get some of that. It’s Yellowstone. The bison are the main characters and they know it.)

The drive is honestly part of the fun

Here’s the thing about the run from Rexburg up to West Yellowstone: it doesn’t feel like a commute. US-20 takes you past the Ashton area, up through Island Park, past pine forests and fishing rivers and those big open Idaho skies the resort is literally named after.

Roll the windows down. Put on the road trip playlist. Accept that someone will need a bathroom exactly seven minutes after you pass the last decent bathroom. It’s the law.

By the time you hit West Yellowstone, Montana and cruise through the gate, the kids are hyped and you’ve had your coffee and everyone’s ready. That’s the magic of a two-hours-ish drive. Close enough to be easy, far enough to feel like a real adventure.

What to actually do with your Yellowstone day

You cannot do all of Yellowstone in one day. Anyone who tells you that you can has never traveled with children. But you can absolutely do a great day. A few game plans depending on your crew:

The classic first-timer loop: Old Faithful, the Grand Prismatic Spring, and the geyser basins. Colors that don’t look real. Steam everywhere. Peak “whoa” factor for kids and adults.

The wildlife morning: Get up early (I know, I know) and head toward Hayden or Lamar Valley for bison, elk, and if the group chat’s luck holds, maybe a bear or wolves way off in the distance. Bring binoculars. Bring more snacks than you think you need.

The waterfalls and canyon play: The Grand Canyon of the Yellowstone and its waterfalls are ridiculous in the best way, and the overlooks are mostly short walks, which your six-year-old will appreciate roughly 15 minutes before declaring their legs “broken.”

Whatever you pick, go in with a plan and a backup plan, because cell service in the park is basically a rumor. Screenshot your maps before you leave the resort’s free WiFi.

Why Idaho Sky is the basecamp move

Staying in Rexburg instead of inside the park isn’t the budget consolation prize. It’s the smart-parent flex.

You get more space and way better prices than in-park lodging, and you come home each day to a place that actually feels good. Idaho Sky RV Resort has extra-large pull-through sites with full hookups if you’re rolling in your own rig, plus vacation cabins and tiny home getaways if “RV” is not currently a word in your vocabulary.

After a long day of walking boardwalks and refereeing “he’s touching my side of the car,” you get two oversized hot tubs, communal fire pits made for s’mores, and a dog park so the family pup isn’t stuck in the RV while you’re off gawking at geysers. There’s pickleball and cornhole for the people who somehow still have energy, 24-hour laundry for the inevitable ice-cream situation, and free high-speed WiFi so the teens don’t stage a revolt.

Basically, the park is the adventure and the resort is the exhale. That’s the whole point.

Beyond the park: fill the extra days

Give yourself more than one night and you’ve got a whole eastern Idaho lineup within easy reach of Rexburg. Cast a line on the world-famous Henry’s Fork up near Island Park. Chase the boardwalks at Mesa Falls near Ashton. Let the kids burn a full tank of energy at the St. Anthony Sand Dunes. Cruise into Idaho Falls for dinner and the river walk.

You came to Yellowstone. You’ll leave with a list of reasons to come back. That’s kind of Idaho Sky’s whole thing.
