Twin Falls to Hatch: Hidden Gems on US-93 & UT-20

The 220-mile journey from Twin Falls, Idaho to Hatch, Utah traces a little-known swath of the American West where the Snake River Plain meets the Great Basin. This stretch of US-93 and UT-20 cuts through the historic Minidoka Internment National Monument site, a sobering reminder of WWII-era Japanese American incarceration, before climbing into the volcanic badlands of Craters of the Moon. The route’s highest point, at over 7,000 feet near the Utah border, offers sudden views of the Tushar Mountains—a range that holds Utah’s highest peak outside the Wasatch.

Snowfall can close stretches of UT-20 as late as May, so check conditions. Most travelers ask: how long to drive Twin Falls, ID to Hatch, UT? Plan for 4.5 hours without stops, but allocate a full day to explore. If you're wondering is it worth driving Twin Falls, ID to Hatch, UT, the answer is a resounding yes if you crave solitude and raw geology.

Natural Landscapes: Craters of the Moon National Monument (mile 80) is a surreal lava field with cinder cones and spatter cones. Walk the Devil’s Orchard Trail (0.5 mi) for close-up basalt formations. Further south, the Minidoka Internment Monument (mile 15) offers a 2-mile driving tour through reconstructed barracks—poignant and educational. The Tushar Mountains (mile 190) provide alpine scenery with aspen groves that turn gold in late September.

Local Commerce: Arco (mile 115) is home to the historic Boondocks Restaurant (best pie in Idaho). In Hatch (mile 220), try the Hatch Station Cafe for green chili burritos. The town of Carey has a single general store selling handmade quilts and local honey. Cash is preferred at roadside farm stands selling huckleberry jam near the border.

UNESCO World Heritage Sites: None directly on route, but the nearby Yellowstone National Park (3 hours north) is a UNESCO site. The route itself passes through the Great Basin, which is part of a UNESCO Biosphere Reserve. For a quick detour, turn east at US-20 to reach the Golden Spike National Historical Park (1.5 hours off-route), honoring the transcontinental railroad—a UNESCO tentative site.

Infrastructure Safety & Road Quality: US-93 is mostly straight with wide shoulders; UT-20 has narrow stretches and no guardrails on steep drops. Winter travel requires snow tires—chains may be required on UT-20. No highway lights beyond city limits; drive judiciously at night. Wildlife (deer, elk) is common at dusk near the Fishlake National Forest.

Family and Child Suitability: Kids love the lava tubes at Craters of the Moon (flashlights required). The Minidoka site has interactive exhibits suitable for ages 8+. Rest stops with playgrounds are available at the Arco City Park (mile 115) and the Beaver View Rest Area (mile 200, pit toilets only).

Pet-Friendly Framework: Most attractions allow leashed pets outdoors; Craters of the Moon permits dogs on trails. The only pet-friendly lodging is the Super 8 in Arco ($20 pet fee). Rest stops have designated pet areas but no shade—bring water. Fatigue Management: Every 2 hours, stop at the Craters of the Moon Visitor Center (mile 80) or the Minidoka Interpretive Center (mile 15). Power naps in the car are safest at rest areas with tables (e.g., mile 50 near Carey).

Hidden Off-Route Spots: Detour 10 miles east on US-26 to see the Ebrima Bridge, a historic steel truss bridge over the Little Lost River. Another gem: the Kelton Trail (mile 170), a dirt road leading to abandoned stagecoach stops. For a true secret, ask locals in Hatch about the "Pink House", a former brothel turned art studio.

Climatic Conditions & Route Aesthetics: Summer temperatures reach 95°F (35°C) on the Snake River Plain, dropping to 60°F (15°C) in the mountains. Fall offers crisp air and golden light for photography. Spring brings wildflowers on UT-20 (May–June). Snow can linger on the road shoulders until July at high elevations. The best months for color and comfort are September and early October.

Culinary Infrastructure: Besides Boondocks in Arco, try the Lost River Grill in Mackay (20 miles north of Arco, worth the detour) for bison burgers. In Hatch, the Hatch Station Cafe serves breakfast all day; the green chili chicken enchiladas are legendary. For a quick bite, the Sinclair station in Junction sells surprisingly good hot dogs. Vegetarians may struggle—pack snacks from Twin Falls’s natural foods co-op.

US-93 is well-maintained two-lane highway; UT-20 is a narrow mountain road with sharp curves. Gas stations are sparse beyond Twin Falls—top up in Carey (50 mi) or Arco (85 mi).
