Despite GPS telling you otherwise, the easiest way to enter the Park is to turn E off Hwy 16/20 (at Brandies Candies & across from Family Dollar) onto 4th Ave N. Go straight 4 blocks directly into the Park. You will be driving through a small town neighborhood and there are NO STOP SIGNS on our cross Streets, so drive slowly, and be prepared to yield at all intersections.
Coming from the East? You can come over the Big Horn Mountains via Hwy16 from Buffalo to Worland (the southern route) or Hwy 14 from Sheridan to Greybull (the northern route). Both go over the Big Horn mountains, both take you through stunning mountains and end in spectacular canyons and both are about the same distance.
RV'ers tend to find Hwy 16 easier, with fewer switchbacks and steep grades. Both are stunning mountain drives that you will want to drive during daylight and remember for a lifetime.
Of NOTE: Hwy 16 should be taken all the way to Worland, then Hwy 14/16/20 to Greybull.
A relaxed, do-it-all guide to the heart of the Big Horn Basin
Welcome to Greybull and the Big Horn Basin! Whether this is your first trip to Wyoming or you're a seasoned camper, you've picked a wonderful home base. From your site here at the KOA you're within easy reach of mountain passes and hot springs, ancient dinosaur tracks and wild horses, badlands and boat rides. The trouble isn't finding something to do — it's fitting it all in.
So here's our suggestion: give yourself four days. One to slow down and enjoy town, one for the epic mountain “Loop,” one for the dinosaurs and hot springs of Thermopolis, and one for the local wonders hiding right in our own backyard. Mix the order to suit the weather and your energy — and always keep a jacket and a full tank handy.
Every good trip needs a day to catch your breath, and Greybull is a lovely place to do it. Start slow with a coffee — the Dry Bones Coffee Hut near the south bridge, Wild Sage Coffee House for breakfast and something sweet, or Bob’s Bakery for a proper small town diner breakfast. Then stretch your legs on the Town Walking Path, a paved trail that runs the length of town alongside the Big Horn River. You can step right onto it from the KOA — the gate is by the tent area on the northeast side. (Follow the mulch path our gracious neighbor lets us use until you reach the pavement.) It’s about three beautiful miles of paved river walk, complete with birdsong, deer & even wild turkeys. Dogs on a leash are welcome too.
Wander back into town along Main Street to browse the shops and duck into the library and its free local museum. Lunch is easy: grab a burger at the A&W Drive-In (closed weekends), a real pizza at CC’s, or a sandwich and hand-dipped chocolates at Brandi’s Candies. Keep an eye out for food trucks parked around town all summer long. Want something for the grill? Local meats available at Flying E, local honey and fresh eggs can be found at Queen Bee and you won’t want to miss shopping at the Crazy Woman store or the Mercantile for your local western flare.
Spend the warm part of the afternoon right here at camp. Our swimming pool is open from 9 a.m. to 9 p.m. for registered guests, Memorial Day through Labor Day — the perfect way to cool off. Cap the evening with an ice cream from the KOA store and a quiet sunset over the basin.
Local lore: Hear a siren at 9 p.m. sharp? Don’t worry — it’s an old town curfew (and a nightly hearing test for our beloved volunteer fire department). It’s tradition, not trouble.
This is the one you’ll be telling folks about back home. “The Loop” is an epic drive of roughly 150 miles up and over the Big Horn Mountains on Highways 14 and 14A. Pack a picnic, top off the tank, bring layers, and give yourself the whole day. Head east out of town on US-14 toward Shell. (You’ll pass the turnoff for the Red Gulch Dinosaur Tracksite — we’ve saved that gem for Day Four, so press on up the canyon today.)
Stop at the Old Shell Store for a hamburger or homemade ice cream sandwich, then climb into Shell Canyon. Don’t miss Shell Falls, where more than 3,600 gallons of snowmelt thunder over the rocks every second. Continue up to Burgess Junction — you can even rent a side-by-side here for a spin on the mountain trails — then take 14A toward Lovell, watching the tree line for moose and elk.
A little detour up Forest Road 12 brings you to the Medicine Wheel, a sacred Native American site more than 800 years old, sitting at 9,642 feet. It’s a strenuous but stunning 1.5-mile walk from the ranger station (the rangers may let you drive up if the hike isn’t for you). Standing in the clouds with the wind rushing past, you’ll understand why it’s held sacred. Bring that jacket — it can be cold up here even in July.
Coming down the mountain, detour north on Highway 37 to the Bighorn Canyon Recreation Area and the Devil’s Canyon Overlook where you can marvel at the dizzying red walls, take a scenic boat tour, or simply enjoy the big horn sheep and the Pryor Mountain wild horses who call this canyon home. On the way back, stop at the Wild Horse Mustang Center in Lovell to learn where the herd is roaming. Then follow 14A to Highway 310 and roll on back to Greybull to close the Loop.
Before you go: 14A is a seasonal mountain road — open June -October, but If it’s closed, the half-Loop is still a beautiful day. Wyoming weather can be tricky, snow in June on the mountain is possible. Dial 511 or check wyoroad.info for conditions and always carry a paper map!
Point the car south on US-16/US-20 and settle in for the roughly 70-mile drive to Thermopolis, home to dinosaurs and healing waters in equal measure. First stop: the Wyoming Dinosaur Center, one of the finest dinosaur museums anywhere, with nearly 20,000 bones pulled from the bonebeds right outside town and mounted skeletons from around the world.
If your crew has the itch to get their hands dirty, book the Dig for a Day program ahead of time and head out to an active excavation site to unearth real fossils with real paleontology tools. Kids and grown-ups both come back grinning. (Hours and dig times shift by season, so call ahead or check wyomingdinosaurcenter.org to reserve.)
Afterward, soak away the miles at Hot Springs State Park. The State Bath House is free — yes, free — with indoor and outdoor mineral pools kept at a soothing 104°F (soaks are traditionally capped around 20 minutes, and it’s open Monday–Saturday and Sunday afternoons). Stroll the boardwalk across the colorful mineral terraces, cross the swinging bridge over the Big Horn River, and keep an eye out for the park’s resident bison herd.
Save a little daylight for the drive home, because the best is nearly last: continue a few miles south on US-20 into the Wind River Canyon. Towering walls rise on either side as the river races beside you — and thanks to an optical trick of the canyon, you may find yourself swearing the water is flowing uphill. It’s a jaw-dropper. Turn around when you’ve had your fill and enjoy the golden-hour drive back to Greybull.
You don’t have to drive far to be amazed — today’s adventures are practically next door. Start with a step 167 million years back in time at the Red Gulch Dinosaur Tracksite, just east of town off Red Gulch Road (a good dirt road when dry). Here you can literally walk among the footprints of Middle Jurassic dinosaurs, preserved in stone. Hunt the rock walls and ground for “devil’s toenails” — curled, fossilized shells from an ancient sea that once covered all of this.
Next, seek out Devil’s Kitchen, a hidden badlands amphitheater about five miles east of Greybull. You round a bend and the ground suddenly drops away into a bowl of red-and-orange spires, ravines, and eerie rock towers — a moonscape most visitors drive right past. It’s a compact spot you can explore in an hour or two, with a steep little descent from the parking area. Stop by our office and we’ll point you to the turnoff.
Fair warning: Both the tracksite and Devil’s Kitchen sit at the end of dirt roads that turn to gumbo when wet — save them for a dry day, bring water, and watch your footing near the edges.
Round out the day at the Museum of Flight and Aerial Firefighting at the Greybull airport with access at the rest area. Greybull was once home base for the legendary air tankers that fought wildfires across the West, and this open-air museum lets you walk right up (and into some) of those retired giants — a Neptune P2V-7, a C-119, a KC-97, a PB4Y and more. It’s open Monday through Saturday, 9 to 5, from mid-May through September (weather permitting, since much of it is outdoors). Aviation buffs and kids alike will love these old warbirds.
Then it’s a short hop home for one last camp dinner — fire up the grill, or treat yourselves to dinner in town at Lisa’s, Los Gabanes, or the Speakeasy — and toast four days well spent.
Wyoming can be very windy — always put your awning up before you leave camp. Mountain weather changes fast, so pack a jacket even on hot days. Unpaved roads can be impassable when wet, so check the sky and the forecast before heading to Devil’s Kitchen, the tracksite, or up the mountain. For road conditions, dial 511 or visit wyoroad.info, and always carry a physical map — cell service can be spotty out here.
Most of all, relax and enjoy. We’re so glad you came. If you loved your stay, we’d be delighted if you’d say hello on Facebook or leave us a review. Safe travels, happy campers!
