A 3-day Idaho loop out of Boise: a ski-town evening in Sun Valley, the single best mountain overlook in the state at Galena Summit, a swim at an alpine lake below jagged granite spires, a Salmon River rafting run, and a soak in a riverside hot-springs pool — with real lodges, outfitters and 2026 prices throughout.
Day 1Boise to Sun Valley
A scenic drive northeast out of Boise into ski-town Ketchum and Sun Valley for the first night.
🚗 Drive — Boise to Ketchum/Sun Valley
~2.5–3 hours via ID-21 & US-20/ID-75
A straightforward highway run east out of the Treasure Valley into the Wood River Valley, with the Boise Mountains and Camas Prairie giving way to sagebrush flats as Sun Valley’s peaks come into view.
🚶 Ketchum Historic Downtown & Ernest Hemingway Memorial
~1.5–2 hours
A walkable former mining and sheep-ranching town turned ski village, with a short detour out Trail Creek Road to the quiet streamside memorial where Hemingway, who lived and died here, is remembered.
🍽️ Dinner — The Pioneer Saloon, Ketchum
~1.5 hours · Est. $30–$50 USD / person
A Ketchum institution since the 1940s, known for prime rib and a trophy-mounted dining room that hasn’t changed much in decades.

🛎️ Overnight — Sun Valley Lodge, Sun Valley Resort
From $350–$500 USD / night, for 2 people
America’s first destination ski resort, opened in 1936 — the lodge’s wood-paneled lobby, outdoor ice rink, and mountain-view rooms make it worth one splurge night before the drive into the backcountry.

Day 2Galena Summit, Redfish Lake & the Salmon River
North over the highest paved pass in the Northern Rockies, a lake swim below the Sawtooths, and an afternoon of whitewater.
📸 Galena Summit Overlook
~30–45 minutes · free
At 8,701 feet, the highest highway summit in the region and the single best roadside view of the Sawtooth Range — the entire jagged skyline and the headwaters of the Salmon River spread out below the pullout.
🏞️ Redfish Lake Beach & Day-Use Area
~2 hours · day-use parking fee applies
Idaho’s largest alpine lake, named for the sockeye salmon that once ran here, with a sandy beach directly beneath Mt. Heyburn’s granite spires — an easy swim or picnic stop at the heart of the Sawtooth Wilderness.
🚣 Whitewater Rafting — Salmon River
~3–4 hours · approx. $95–$120 USD / person
A half-day float on the Salmon’s upper stretch near Stanley, reading water through Class II–III rapids below the same peaks seen from Galena Summit that morning.

Day 3Stanley Back to Boise
A bakery-counter breakfast under the Sawtooths, then a second, greener scenic byway back to the city.
🥐 Breakfast — Stanley Baking Company & Cafe
~1 hour · Est. $12–$20 USD / person
A tiny log-cabin bakery that draws a line out the door most summer mornings, with cinnamon rolls and a patio looking straight at the Sawtooth skyline.

🌲 Drive — Ponderosa Pine Scenic Byway (ID-21) to Boise
~2.5–3 hours via Lowman & Idaho City
A greener return route than the way up, following the South Fork Payette River through old-growth ponderosa forest and hot-springs country before dropping back into the Boise foothills.
⛏️ Idaho City Historic District
~45–60 minutes
A wooden-boardwalk 1860s gold-rush town roughly halfway down the byway, once bigger than Boise itself — a few blocks of saloons-turned-shops make for an easy leg-stretch stop before the final run into the city.
🚗 Arrive Boise & Depart
~1 hour from Idaho City
A straightforward final descent into the city to close out the loop.
