DIY Guide to Fly Fishing Gibbon River in Yellowstone National Park

In the Northwest corner of Yellowstone National Park lies the Gibbon River, a tributary to the Madison River

Many world-class fisheries exist in Yellowstone and the Gibbon River is one that is often overlooked.

Trout stocking programs in the early 1900's lead to thriving population of rainbows, browns and brook trout the river currently enjoys.

The National Park Service has recently embarked on efforts to restore native westslope cutthroat trout to the upper Gibbon River.  To assist in the effort, there is no possession limits of non-native trout species including brown, rainbow, and brook trout in the upper river (above Gibbon Falls.)

Best Places to Fish the Gibbon River

The best fishing waters on the Gibbon River are easily accessed from the main roads in Yellowstone. There are however several places you can only reach by hiking Grand Loop Road out of Gibbon Canyon. 

Even though it fishes well, the Gibbon is usually lower on most anglers' priority list when fishing in Yellowstone. If you are looking to avoid crowds in the busy summer season, the Gibbon is an excellent place to start.

The river is divided into multiple segments, and each has a different mix of trout and specific conditions. Conditions vary between sections and seasons. Some general principles hold true year over year though.

The upper section of the Gibbon River below Grebe Lake, Wolf Lake and through Virginia Cascades is very small. This section has a mixed fishery of very small brook and brown trout along with some Arctic Grayling. 

As the Gibbon River flows past the Norris Campground, it picks up size and is now a more fishable stream with large pockets, pools, and undercut banks that holds some sizable brown trout.

Below the Norris Geyser Basin, the Gibbon flows through Elk Park and the Gibbon Geyser Basin. Both of these areas are characterized by open meadows with winding pools and undercut banks. The meadows here are favored by fly fisherman.

Continuing on past Gibbon Geyser Basin the river passes Beryl Springs.  Here the river picks up speed and enters Gibbon Canyon on it's way to Gibbon Falls.

Finally, making its' approach to Madison Junction, the Gibbon opens up into another meadow section that some refer to as Gibbon Meadows. This is a great spot to target large brown trout with a streamer during their fall spawning run coming up from the Madison River.

Best Time to Fish the Gibbon River

Fishing season is short in Yellowstone (June to November), so your window of opportunity to try your luck on the Gibbon River is limited. The good news is the Gibbon is among the first rivers to clear up after spring runoff season, so you stand a good chance of landing a trophy catch if you can visit in late June.

Summer is peak season for both fly hatches and tourists, so plan on dealing with traffic, other anglers at popular fishing locations throughout the park, and people stopping to observe the natural wonders of Yellowstone.

Gibbon River Fishing Tips

A 9-foot rod with 4 or 5-weight floating fly line is recommended for the Gibbon River.  You should also pack waders without felt soles (state and park regulations prohibit these).
