2 nights near kalispell

Hey guys, looking for some advice. Going to have 2 nights to spend in the backcountry the first week of august.

Call it within a 2 hr drive of kalispell. Looking to hike 10-15 miles in and set up camp. Ideally an out and back that doesn’t require moving camp. Also, ideally no permits. Priorities are solitude and quality of the fishing with scenery being a distant 3rd.

Tossed around the idea of doing the middle fork flathead but it seems like an alpine lakes route may be a better option. Got option overload when i started researching the lakes.

Appreciate any input or advice.

Thanks!
