East Gallatin River Hidden Access
An unmarked river access on the East Gallatin just downstream of the Kelly Canyon Road bridge, where a faint social trail through cottonwoods and willows leads to a series of deep swimming holes and trout pools that the tubing crowd doesn't know exists.
The Kelly Canyon bridge area is a zoo on summer weekends — tubers, rafters, people everywhere. This access, just downstream behind the vegetation on the east bank, is the spot the fly shop staff direct regulars to when the main section is blown out with people. The fish are still there. Most of the people aren't. Dan Bailey's in Bozeman specifically recommends this stretch to clients seeking less-pressured water.
From Bozeman, take Kelly Canyon Road east approximately 6 miles to the bridge over the East Gallatin River. Park on the wide shoulder just west of the bridge — east bank parking is limited and often blocked by ranch gates. Look for the faint social trail on the east (south) bank immediately downstream of the bridge. Follow it 50-100 feet through the riparian brush to the first major swimming hole. The approach is brushy in early summer but opens up by August as flows drop.

The East Gallatin has a public face and a quiet one. The public face is the Kelly Canyon bridge on a Saturday in July — tubes, kids, coolers, everyone in the water at once. The quiet face is the east bank 50 feet downstream, behind a screen of cottonwoods and willows, where the same river runs over a series of rocky pools that see a fraction of the traffic.
The approach is the filter. There’s no signed trailhead, no maintained path — just a faint game track that the people who use this spot regularly have worn into the bank. You follow it through the riparian brush, a little scratchy in June, open and easy by August, and in a few minutes you’re at the water’s edge at the first deep hole.
Fish-wise, this section holds rainbow and brown trout that see significantly less pressure than the main access points. Nymphs and streamers work the deeper holes, particularly during morning and evening feeding windows. The riffle-to-pool structure is classic Montana river — cast into the head of the pool, let the fly swing through, pick up at the tail. Montana Fish, Wildlife & Parks Region 3 biologists use this section for seasonal trout surveys, which tells you something about its health as a fishery.
Water levels define the experience. Mid-July through September, when flows stabilize and temperatures push into the mid-60s, is when this spot is at its best for both swimming and fishing. Spring runoff makes the approach muddy and the holes fast and cold. Check current USGS gauge data for the East Gallatin before making the drive.
Valid Montana fishing license required. Check current regulations for the East Gallatin at Montana FWP before your visit — seasons and specific rules apply.
