Alta sits on the Idaho side of the Teton Range, but its fishing draws from a mix of high-country lakes and moving water that most visitors overlook in favor of the more-publicized spots across the state line. The options here split cleanly between lake fishing and river fishing. On the lake side, you have Taggart Lake, Ernest Lake, Grizzly Bear Lake, Tillery Lake, and Bergman Reservoir — each with its own access situation and character. For moving water, Reunion Flat and Teton Canyon offer river fishing in very different settings: Reunion Flat tends to be more open and wade-friendly, while Teton Canyon puts you in tighter terrain where reading the water matters more than casting distance. This is not a destination where you show up and fish from a parking lot. Most of the lake access involves some hiking, and the river stretches reward anglers who take time to scout before they wade in. Shoulder seasons — late spring and early fall — generally mean less pressure and more cooperative fish, though summer mornings before the afternoon wind picks up can be productive across all these waters. If you are coming from out of state, Wyoming and Idaho licensing rules both apply depending on exactly where you are fishing, so sort that out before you go.
Alta straddles the Wyoming-Idaho border, so the answer depends on the specific water you are fishing. Waters on the Idaho side of the line require an Idaho license, while Wyoming waters require a Wyoming license. Some anglers fishing the area carry both to avoid any ambiguity, especially on boundary waters. Check the exact location of each spot against state boundary maps before you buy.
These are backcountry lakes that require hiking in rather than driving up to. Trail lengths and elevation gain vary, so check current trail conditions through the Caribou-Targhee National Forest before your trip. Give yourself enough time to fish and get back out before dark, especially if you are not familiar with the terrain.

Reunion Flat is a more open stretch of river that tends to be easier to wade and read, making it a reasonable choice if you are newer to river fishing in the Tetons. Teton Canyon is more confined, with the kind of structure that rewards anglers who slow down and work specific pockets and seams rather than covering water quickly.
Early morning is consistently the most productive window across both the lakes and the river stretches near Alta. Afternoon winds can make lake fishing frustrating and put river fish down. If you can only fish one window, be on the water at first light and plan to wrap up by midday.
Bergman Reservoir is generally more accessible than the high-country lakes in the area, making it a practical option if you want lake fishing without a long approach. That said, confirm current road and access conditions locally before you go, as seasonal closures and road conditions in this part of Wyoming can change the picture.
