Thanks for the info! We camped next to Quiniscoe Lake but I heard several times that Ladyslipper is the place to go. I should have specified that I was spincasting. A small spoon worked great.
Quiniscoe had tons of small rainbows and cutthroats in the 6-10" range but everything I caught there was super skinny. Pretty amazing to get almost nonstop bites in these lakes, compared to the fished out lower mainland locations I usually try! Fished for 15 minutes at dusk on our second night and got lots of bites. Landed 2 small rainbows and one cutthroat. The cutthroat was around 8":
Ladyslipper was a bit of a trek up and over a high ridge but the colour of the lake was amazing and the scenery is spectacular:
Caught a 7" rainbow on the first cast! Threw that one back and made my way around the bay, trying various spots. Landed a 12"-ish rainbow about 30 minutes in, and another about the same size 90 minutes later. Lots of bites in between and I could see some smaller fish (3-8") following my lure back. Saw one big trout, probably 15", cruise by my lure but he wasn't interested :/ Hooked another 12" right at the end of the day but he got away. I know my ruler isn't quite on the mark in the first shot
Overall, the scenery is fantastic and the fishing is awesome. The hiking is also pretty great up there and you get to bump elbows with the pack of resident goats who aren't scared of the people:
Didn't make it to Haystack because it was pretty far off.
Thanks to VAGAbond and Renegade for weighing in
