Go to the Montana Fish and Wildlife website and you can search Golden Trout lakes in Montana. Here is a link to Region 3 in Montana which lakes contain the elusive Golden Trout. Montana Fish, Wildlife & Parks :: Waterbody Search Results
Also, every lake that is going to have Golden Trout in the state will probably take some hiking. This is because the Golden Trout require colder water temperature because they do the best in water temperatures between 50-60 degree range. If you are up for a drive I suggest trying Sylvan Lake up the East Rosebud drainage outside of Fishtail, Montana. It is one of the easier hikes to get the Golden Trout and produce high end average size of around 12". Goldens average size are 6-12". Also, there are only about 20 lakes in the state that has the Golden one and several that have a cross between the Golden with Cutthroats or Rainbows. Sylvan provides about a 5-6 mile hike to the lake. It is a little steep but not too challenging if you are in shape. I actually did this with a buddy at night with headlamps on in the rain. The trail on top leads to an open meadow where the trail disappears. However, there is a big rock marker and proceed straight from there in to small timber that hooks back up with the trail. There is a good youtube video showing this if you search Sylvan Lake in Montana however mute it, as the music is corny. Sylvan has the purest forms of the Golden and a large percentage of the other Golden Trout lakes were stocked with the Golden from Sylvan such as Cave Lake in the Crazy Mountains which holds the current state record. My favorite Golden Lake is Lightning Lake but it takes will, determination, and guts to set foot on the shores of this castle. It is a beautiful fish to catch but takes some skill to land one of these. Try black ants and adam flies 16-22 size or maybe even a streamer. Goldens do not eat their own kind and mainly eat terrestrial food. I had the best luck floating a clear bobber and having a long leader with a size 4 hook with a worm on it. Hope this helps you guys out.

I will help you out even more as I am bored so I looked up on the Fish and Game website which lakes in which region has Golden Trout. I didn't write all the ones down that probably have crosses. A Cutt x Golden cross is always fun by the way and it happens more than you think when they are dropping in stock and by accident drop the stock in the wrong lake.
Island Lake- GT
Cresent Lake- GT, RB, CT so assume crosses as these fish like to do that
Cliff Lake- GT, RB, CT assume crosses again
Glacier Lake: EB, GT, RB, CT assumes crosses
Region 2: Fish and Game Reports None
Blue Danube Lake-GT
Skytop Lake- GT
Blue Paradise Lake- RB, GT cross you can assume
now to dbrowers post:
Hidden Lake of the Madison drainage reports: LL (Brown), RB CT but no GT
Golden Trout Lake- No stocking...and since Goldens are not usually self-sustaining you might get lucky and find one that is? I would contact local Fish and Game or go to Fly and Tackle shop....they could help you out more on this. I know Pat Marcusson was an instrumental Biologist that did a lot for the stocking of the Golden Trout but with his retirement the stocking of Golden Trout has been limited to funds available.
Region 4: None Reported
Basin Lake- GT
Big Butte Lake- GT
Cave Lake- GT Current State Record
Desolation Lake- LL & GT
Dryad Lake- GT
Incisor Lake- GT
Lake Mcknight- GT
Lake at Falls- GTxCT Beautiful fish here
Lightning Lake- GT and someday they State Record once Again
Martin Lake- GT
Rock Tree Lake- GT
Scat Lake- GT
Sunken Rock Lake-GT
Sylvan Lake- GT
Do some research and pick a lake. If you are up for a drive I still think Sylvan might be your best bet. I was searching catch of the day by Simms and some guy from Minnesota had the catch of the day a 23" GT in Wyoming some where. I looked at the picture and question the fish afterwards. Looked like a CTxGT cross of a Yellowstone Cutthroat. Sometimes it is really hard to tell because they have similar characteristics. Not saying it wasn't but looking at the fish it had CT characteristics with the Golden Spots. It looked very similar to the GT X CT at Lake at Falls. Anyways, this should provide you with a lot more information then you have been given.
