Main Salmon River Rafting: 5-Day Expedition

The Main Salmon River is an active wilderness trip. Guests should be comfortable being in or near moving water, climbing in and out of rafts from a beach, and spending most of each day outdoors. No prior rafting experience is required, your guides handle all technical navigation. The most physically demanding moments are the optional hikes to homesteads, hot springs, and historic sites; these are always voluntary and range from short riverside walks to longer canyon explorations. If you have specific health concerns or limited mobility, call us before booking, we'll give you an honest assessment of what this trip involves.

Camp life on the Main Salmon is genuinely comfortable. Broad sandy beaches provide flat, spacious camping areas backed by old-growth ponderosa pine. Cots are provided, you lay your sleeping bag on top and sleep about four inches off the ground, well clear of the sand. Tents are available for guests who prefer them or when weather warrants. Camp chairs, a portable toilet system, and a full kitchen setup are established by your guides each evening before you arrive. There are no roads, no towns, and no cell service for the duration of the trip. That's the point.

The Main Salmon River canyon runs warmer than the Middle Fork, daytime temperatures typically climb into the 80s–100s°F in the canyon bottom from July through August, with cooler evenings. Water temperatures range from around 40–58°F in June to 55–68°F in July and August, cold enough to warrant a splash jacket in June, comfortable enough for swimming in midsummer. Sun protection (hat, long sleeves, sunscreen) is essential all season. Late-afternoon thunderstorms are possible in July and August, your guides monitor conditions and adjust plans accordingly.

See the Main Salmon River Weather Guide for seasonal planning detail.

The Main Salmon runs Class II–IV depending on water levels and time of season. June departures typically see higher, faster water, which is why the minimum age for June is 12 years old; July and August water levels moderate, lowering the minimum age to 6. Your guides brief the group before every significant rapid, explain the lines, and position guests for the safest and most exhilarating run. Strong swimming skills aren't required, and everyone wears a life jacket on the water, but guests need to be able to help themselves if they end up in the river.

Main Salmon trips run with up to 25 guests across multiple boats, creating an instant river community. Guests consistently describe meeting their fellow travelers as one of the trip's unexpected highlights. Families, couples, multi-generational groups, solo travelers, and friend groups all find their place on the river. If your group is large enough to consider a private departure, call us, select dates can be reserved exclusively for your group.

What you wear on the water matters, and it changes by month.

June and early July (high water): A dry suit or splash jacket is strongly recommended. June water temperatures can drop to 40°F and the river moves fast. You may bring your own or rent from Kayak Academy, call 866-306-1825 to arrange rental before your trip.

July and August: Good-quality two-piece rain gear is recommended for the occasional afternoon storm. Ponchos are not effective rain gear on moving water, they catch wind and don't protect when it counts. Pack a rain jacket and pants that breathe.

Weather in Idaho's mountain canyons is generally excellent in summer, but a storm can arrive without much warning. Being prepared takes ten minutes and makes the difference between a great day and a miserable one.

Pack everything you need for five days in a single soft-sided duffel bag, approximately 12" × 13" × 24" in size. Label your duffel and stay within a 20-pound weight limit (not including any beverages you're bringing), aircraft weight allowances and raft space are both factors. Your provided water-resistant gear bag (the large outer bag) wraps your duffel and sleeping bag to keep everything dry. A military-surplus ammo can (approx. 7" × 13") keeps the items you'll want during the day, sunscreen, camera, rain gear, medications, lip balm, dry and accessible from the boat.

Bring:

• Photo ID, a major credit card, and cash for guide gratuities
• Camera with a waterproof case, phones in waterproof sleeves work well (cell service unavailable on the river)
• A water bottle and carabiner to clip it to the raft
• Sun protection: hat, sunscreen, long-sleeve sun shirt
• Personal medications and prescription glasses, pack these in your carry-on, not checked luggage, in case of airline delays the night before your trip
• Extra snacks or specialty drinks if you have them (water and lemonade are provided; soda is not)

Leave at home (or at the hotel):

• Suitcases or hard-sided luggage, these cannot go on the river or the charter flight
• Unnecessary electronics, valuables, and jewelry, no safe storage exists on the river
• Rings, we recommend leaving them home; we lose a few to the river every season

After your final riverside lunch on Day 5, your group takes out at Carey Creek and boards the bus to McCall, Idaho. If you added the full Boise Travel Package, you'll spend the night at the Third Street Inn in McCall before a morning ground transfer back to Boise (approximately 2 hours). Check your confirmation for shuttle pickup times.

If you have bags you're not taking on the river, a second suitcase, a carry-on you packed just for the flight, you can leave them at the Best Western Vista Inn while you're on the water. They'll be there when you return to Boise at the end of the trip. Do not bring suitcases or hard-sided luggage on the river or the charter flight.

If you arrive a day early or extend your stay after the trip, Boise's riverside greenbelt is an easy walk or e-bike ride from the Vista Inn. Scooter and e-bike rentals are available near the hotel for exploring the city's restaurants, shops, and waterfront parks.

The Stagecoach is the meeting location for guests driving to Salmon only. Orientation is held on the back lawn the night before the trip.

At 7:30 am the following morning, all of the Main Salmon guests (including those flying in from Boise and Salmon guests) gather at the Stagecoach Inn where the bus departs for the Corn Creek put in.

The bus follows the Salmon River west for approximately two hours into the Frank Church Wilderness. A stop at the general store in North Fork allows guests to pick up any last-minute items. The bus descends into the canyon and arrives at Corn Creek, where the rafts are loaded and ready.

At the end of the trip, your group takes out at Carey Creek and all guests travel to McCall. If you added the driving travel package, your vehicle will be waiting at the Third Street Inn. If you chose not to add the vehicle shuttle, you will need to arrange your own transportation from McCall back to Salmon or onward.

The picturesque town of McCall sits on the southern shore of Payette Lake in the heart of central Idaho's mountain plateaus. Stroll the main street for shops and restaurants, or head down to the boat harbor for lake activities. Many guests add a night or two here before heading home.
