Your First Boise River Float

Before you leave the house

Two checks: the river flow (500–1,500 cfs is the typical comfortable range) and the time. The float takes 2–3 hours and the last shuttle leaves at 9 p.m., so a late-afternoon start is the practical cutoff — the conditions card on our homepage shows a suggested last-launch time based on today's sunset.

Wear a swimsuit and covered shoes that can get wet — the river bottom is rocky, and bare feet or loose flip-flops are the most common first-timer regret. Bring sunscreen, water, snacks (no glass anywhere in the parks or on the river), and a small dry bag for your phone and keys. There's a full packing checklist on the homepage.

Bringing your own tube? Inflate it at home. The air stations at Barber Park have been removed, so arrive ready or pack a pump.

At Barber Park

The put-in is at 4049 S. Eckert Rd., about 15 minutes southeast of downtown. Parking is $7 per vehicle (plus 50¢ if you pay by card), and there's no re-entry to the fee lot — use the drop-off area if you need to come back for gear or people.

Renting is the simplest first-timer move — everything's handled at the put-in, and rafts and kayaks come with paddles and life vests. 2025-season prices, plus tax:

Rafts and kayaks are $10 off on Wednesdays. A free life jacket loaner station is at the put-in — kids 14 and under must wear one on rafts and kayaks (Idaho law). Return loaners at the Ann Morrison kiosk.

On the water

The current does the work — it's a drift, not a paddle. All three Class II rapids come in the first half, so the roughest part is behind you early:

• 1.Bubb Dam (about 20 minutes in) — the biggest: a 2–3 ft drop over a diversion dam. Stay centered, hold on, keep your feet up.
• 2.Rock Garden (about a mile later) — a splashy rocky stretch. Steer for the main channel.
• 3.Mesa Dam (a half mile after that) — a smaller 1–2 ft drop. Smooth water from here on.

If you end up swimming: stay calm, point your feet downstream, and let your life jacket do its job. The second half is the mellow, scenic part — under the bridges, past Boise State and Julia Davis Park. Floater rest areas with restrooms sit around Baybrook Bridge (mile 3) and in Julia Davis Park (the last one before the take-out). Every rapid, bridge, and rest stop is on our interactive float map.

The take-out — don't miss it

The exit is on the left side of the river at Ann Morrison Park, shortly after the 9th Street bridges. Start working toward the left bank once you pass under Capitol Blvd — it's much easier to move with the current than against it. A diversion dam that floaters can't pass sits about a quarter mile downstream of the take-out, so if you somehow miss the exit, get to the left bank immediately.

Getting back to your car

The shuttle bus runs from Ann Morrison Park back to Barber Park for $4 per person, noon to 9 p.m. — every hour on the hour on weekdays, every 20 minutes on weekends and holidays. One catch worth knowing: your tube or raft must be deflated to ride, so pack that pump if you plan to bus back with your own gear. Groups often skip the fee by leaving a second car at Ann Morrison (parking there is free), and cyclists stash a bike at the take-out and pedal the Greenbelt back.

Five first-timer mistakes

• •A pool float instead of a river tube. The rocky bottom and the drops shred thin vinyl. Heavy-duty tubes survive; pool toys often don't.
• •Launching too late. 2–3 hours on the water plus logistics — and the last shuttle is at 9 p.m.
• •Bare feet or flip-flops. You will stand on rocks at some point. Wear shoes that strap on.
• •No plan for phone and keys. A small dry bag clipped to your tube solves both.
• •Glass or booze. Glass is banned in the parks and on the river, and the official guidance is blunt: alcohol and the river don't mix.
