Overview
Star Valley is a high-elevation agricultural valley in Lincoln County, western Wyoming, stretching roughly 40 miles along the Salt River between the Salt River Range to the east and the Wyoming Range to the west. The valley sits at an elevation of around 6,000 feet and contains a cluster of small towns — including Afton (the largest and county seat of the area), Thayne, Etna, Freedom, and Smoot — that collectively form what locals refer to as Star Valley.
The region has a strong Swiss and Scandinavian settler heritage, which partly explains its long dairy-farming tradition. Star Valley Cheese, produced in Thayne, is a well-known local product that has drawn regional attention for decades. The landscape is defined by open ranchland, cottonwood-lined riverbanks, and dramatic mountain backdrops that make it visually distinctive even by Wyoming standards.
Star Valley is not a tourist hub in the way Jackson Hole is — roughly 90 miles to the north — and that relative quietness is a significant part of its appeal. Visitors typically come for outdoor recreation, a slower pace, and access to landscapes that see far less foot traffic than the more famous corners of the state. Cell service and amenities become sparse outside of Afton, so preparation matters.
Before You Go
Visas
Star Valley is in the United States. For visa requirements specific to your nationality, check TravelerPulse's Visas section and the official U.S. Citizenship and Immigration Services website (uscis.gov).
When to Go
- Summer (June–September): The most popular season. Temperatures are warm and pleasant, wildflowers are in bloom, and all outdoor recreation — hiking, fishing, cycling, and camping — is accessible.
- Fall (September–October): Aspen foliage turns gold across the surrounding ranges. Hunting season begins and the valley takes on a quieter, moody character.
- Winter (November–March): Snowmobiling is a serious draw, with trail networks accessing high-elevation terrain. Roads can be hazardous; check Wyoming DOT road conditions before travel.
- Spring (April–May): Mud season. Some forest roads and trails remain closed. River fishing can be excellent as runoff peaks.
Altitude
At approximately 6,000 feet, some visitors from low-elevation areas may notice mild effects — headaches, fatigue, or dehydration — in the first day or two. Hydrate well and limit strenuous activity on arrival.
What to Pack
Even in summer, evening temperatures drop significantly. Layer clothing for mornings and nights. Sun protection is important at this elevation. If visiting in winter, full cold-weather gear is essential.
Getting There
Star Valley has no commercial airport. The nearest commercial airports are Jackson Hole Airport (JAC) approximately 90 miles north, and Idaho Falls Regional Airport (IDA) in Idaho, roughly 90–100 miles west. Salt Lake City International Airport (SLC) is a larger hub about 200 miles to the south, often offering more flight options and competitive fares.
Driving is the standard way to reach Star Valley. US-89 runs through the entire length of the valley and is the main artery connecting it to Jackson to the north and to the Utah border to the south. The pass north of the valley on US-89 (connecting to Hoback Junction near Jackson) involves steep grades and can be closed or difficult in winter — verify conditions with Wyoming DOT at wyoroad.info before traveling.
There is no regular intercity bus or train service serving Star Valley. A rental car from Jackson, Idaho Falls, or Salt Lake City is the practical choice for most visitors.
Getting Around
A personal or rental vehicle is essentially required to move around Star Valley. US-89 connects all the main communities, and distances between them are short — Afton to Thayne is roughly 10 miles. Side roads into the mountains for trailheads, campgrounds, and dispersed recreation areas are often unpaved; a vehicle with reasonable clearance is helpful.
There is no local public transit. Ride-share apps (Uber, Lyft) have little to no coverage in the area — verify availability before relying on them. Gas stations are available in Afton and Thayne; fill up when you can if heading into more remote areas.
Summer cycling on US-89 is possible but the road has limited shoulder in places and sees highway traffic, including trucks. Mountain biking on forest service roads and trails is popular with those who bring their own bikes.
Where to Stay
Accommodation options are modest and suited to the valley's small-town character. Afton has the greatest concentration of lodging, including a handful of motels and small inns. Some ranch-style accommodations and vacation rentals exist throughout the valley — platforms like Airbnb and VRBO list properties in the area, and these can offer more space and a more immersive local experience.
Camping is a popular and practical accommodation choice. Developed campgrounds in the Bridger-Teton National Forest provide basic amenities; dispersed camping on National Forest land is free (subject to Leave No Trace principles and any local fire restrictions). Check for fire bans — common in late summer — before building any campfire.
Book accommodations well in advance if visiting during peak summer weekends or during popular hunting seasons in fall, as inventory is genuinely limited. Verify current hotel and lodging options through local tourism resources or general booking platforms, as specific properties change over time.
Things to See & Do
Outdoor Recreation
- Fly Fishing: The Salt River is a respected fishery for cutthroat and brown trout. Several access points exist along the valley floor. A Wyoming fishing license is required; purchase through the Wyoming Game and Fish Department.
- Hiking: The Bridger-Teton National Forest borders much of the valley. Trails range from moderate valley walks to more demanding routes into the Salt River and Wyoming Ranges. Confirm trailhead access and conditions at the local ranger district office in Afton.
- Snowmobiling: One of the most popular winter activities. The high-elevation terrain above the valley offers extensive groomed and ungroomed trail networks. Local outfitters and rental operators are available — verify current businesses locally.
- Camping: Dispersed camping is available on National Forest land, and developed campgrounds exist within the Bridger-Teton. Reservations for developed sites can be made through Recreation.gov.
- Wildlife Viewing: Moose, mule deer, elk, and various raptors are commonly seen in and around the valley, particularly near the river corridor and forest edges.
Cultural and Local Attractions
- Periodic Spring near Afton: A natural phenomenon — one of the few known cold-water periodic springs in the world — where water flow cycles on and off at intervals, more pronounced in late summer and fall. Access involves a moderate trail hike. Verify current access conditions locally.
- Star Valley Cheese (Thayne): The cheese factory has historically offered tours and a retail shop. Verify current hours and tour availability directly with the facility before visiting.
- Afton Arch: A large elk-antler arch spans the main street in downtown Afton, a recognizable local landmark and photo stop.
Food & Drink
Dining options in Star Valley are limited and concentrated primarily in Afton. Expect a practical range of American comfort food, family-style restaurants, and fast-food outlets rather than a diverse culinary scene. A small number of locally owned diners and cafés serve the community and are generally reliable for straightforward, filling meals.
Local dairy products — particularly cheese — are a genuine regional highlight worth seeking out. Star Valley Cheese products are available at the Thayne facility and at various local stores. Fresh produce availability is modest; the valley's short growing season means most groceries are sourced from outside.
Grocery shopping is possible in Afton at local supermarkets. Stock up on supplies if you plan to camp or spend time in the backcountry, as options thin out quickly outside of town. Wyoming has no state income tax, but sales tax does apply to purchases.
Alcohol is available in Wyoming. Restaurants and bars serving alcohol exist in Afton; verify specific establishments locally as businesses in small communities can change.
Practical Information
Connectivity
Cell service is available in Afton and other town centers but becomes unreliable or absent on mountain roads, trails, and in some parts of the valley. Download offline maps (such as Gaia GPS or Google Maps offline) before heading out. Do not rely on real-time navigation in the backcountry.
Emergency Services
Star Valley has local emergency services, but response times in remote or backcountry areas can be long. Tell someone your plans if heading into the mountains. The national emergency number is 911.
Banking and ATMs
ATMs are available in Afton. Carry cash for small local businesses, farmers' markets, and rural stops that may not accept cards.
Weather
Mountain weather changes rapidly. Afternoon thunderstorms are common in summer. Always check the National Weather Service forecast (weather.gov) before backcountry trips. In winter, road closures can happen with little notice.
Leave No Trace
Much of the surrounding land is public land managed by the Forest Service. Pack out all trash, respect wildlife distances, and follow any posted fire and camping regulations.
Safety
Star Valley is a low-crime rural community. The primary safety considerations are environmental rather than social.
- Wildlife: Bears (both black bears and grizzlies are present in the greater region) can be encountered on forest trails. Carry bear spray, know how to use it, and store food properly at campsites. Consult the Wyoming Game and Fish Department for current wildlife advisories.
- Winter Driving: US-89 over mountain passes can become hazardous quickly. Carry chains or have a four-wheel-drive vehicle with winter tires. Keep an emergency kit — blanket, water, jumper cables, and basic supplies — in the car.
- Backcountry Preparedness: Trails are not heavily patrolled. Carry a paper map and compass in addition to any digital navigation. Inform someone of your intended route and expected return time.
- Altitude: Physical overexertion on the first day or two can cause altitude sickness symptoms. Acclimatize before undertaking strenuous hikes.
