Boise River Float Guide

Last updated: 2026-06-11

Cold, fast water. The Boise River is dam-released from the bottom of Lucky Peak and stays cold all summer. Wear a life jacket, never float alone at high flows, and respect closures — the river closes when flows make it unsafe. In an emergency, call 911.

The classic Boise River float runs about six miles from Barber Park in southeast Boise to Ann Morrison Park downtown — roughly a two-hour drift at a typical summer flow of 1,200–1,800 cfs. The season usually runs from around Memorial Day through Labor Day, depending on flows out of Lucky Peak; in big snowpack years the official opening can slip into late June. Ada County announces the opening and posts daily status on its float page, linked below.

Logistics are simple once you know the system. Rent tubes or rafts at Barber Park, or bring your own and use the free air station. A seasonal shuttle runs floaters from the Ann Morrison take-out back to Barber Park, so you don't need two cars. Park at Barber Park (paid lot in season) to start, and exit river-left at the west end of Ann Morrison where the take-out is signed. Glass is prohibited on the river, and alcohol rules are enforced — check the current rules on the official page before you go.

The one thing locals stress to newcomers: check the flow before you float. The live River Levels widget below reads the same USGS Glenwood gage officials watch. Typical summer floats happen between 1,200 and 1,800 cfs; above roughly 3,500 cfs the river is considered unsafe for tubes and the county will close the float. Early season, the water is also genuinely cold — it comes off the bottom of Lucky Peak Reservoir — so save the first float for a hot afternoon.

Float season FAQ

Is the Boise River open for floating right now?
Check Ada County's Float the Boise River page for the official open/closed status, and the live River Levels widget on this page for current conditions. The season typically runs from around Memorial Day through Labor Day, but high spring flows out of Lucky Peak can delay the opening into late June some years.
How long does the float take?
About two hours from Barber Park to Ann Morrison Park at typical summer flows of 1,200–1,800 cfs. Early in the season, higher water moves you through faster.
What does it cost?
Floating is free if you bring your own tube or raft — there's a fill station at Barber Park. Tube and raft rentals and the return shuttle are paid concessions at Barber Park; current prices are posted on the concessionaire's site.
What flow is safe for tubing?
Typical summer floats happen at 1,200–1,800 cfs. Above roughly 3,500 cfs, conditions are considered unsafe for tubing and officials may close the float. Check the USGS gage or the widget on this page before you go.
Do I need a life jacket?
Strongly recommended for everyone, and the Barber Park rental includes them. Idaho law requires life jackets for children 14 and under aboard many vessels — verify current rules with Idaho Parks & Recreation before your trip.
