Access is just upstream of Bonneville at a dispersed campsite located at ID-21 mile 93.0 that is a functional access for kayaks and smaller hand carry craft. Bonneville Campground at ID-21 mile 91.5 is also listed as an access in some guides but this puts you in downstream of some good class III/IV. USGS River Mile 131.7.
