Darby sits at the southern end of the Bitterroot Valley, where the Bitterroot River and its tributaries push into increasingly wild country before hitting the Selway-Bitterroot Wilderness. The fishing around here splits pretty cleanly into two types: river and stream fishing at spots like Alta Campground, Fales Flat Campground, Rombo, and Woods Cabin along moving water, and lake fishing at higher-elevation destinations like Watchtower Lake, Kerlee Lake, Nelson Lake, and Lookout Lake. The river access points are generally reachable by passenger vehicle, but several of the lakes involve trail time, so your approach depends on how much you want to hike versus how much you want to drive. Summer is the main window for the alpine lakes once snow clears the trails, typically late June through September. The river stretches fish well from late spring through fall, with early morning and evening being the most productive windows during warmer months. A Montana fishing license is required for anyone 12 and older, and you'll want to check current regulations for the specific water you're targeting since rules can vary by drainage.
You have a mix of river and stream fishing at access points like Alta Campground, Fales Flat Campground, Rombo, and Woods Cabin, plus lake fishing at Watchtower Lake, Kerlee Lake, Nelson Lake, and Lookout Lake. The river spots are more accessible year-round, while the lakes are seasonal and often require a hike to reach.
River access points like Alta Campground and Rombo fish well from late spring through early fall, with runoff typically settling down by mid-June. The alpine lakes such as Watchtower and Lookout are usually accessible from late June or early July through September, depending on snowpack in a given year.

Yes, a Montana fishing license is required for anyone 12 years of age or older. Licenses are available online through Montana Fish, Wildlife and Parks or at local sporting goods retailers. Check the current FWP regulations booklet for any special rules that apply to the specific water body you plan to fish, as restrictions can vary.
Most of the lakes in this area involve trail hiking rather than roadside access, so plan on carrying your gear in a pack. Trail lengths and conditions vary, so it's worth checking with the Bitterroot National Forest's Darby Ranger District before you go for current trail status and any wilderness permit requirements.
For river spots, a medium-action spinning rod or a fly rod in the 4-6 weight range covers most situations. For the alpine lakes, a light spinning setup with small lures or bait rigs tends to be practical since you're carrying everything in. Waders are useful at the river access points, especially in early season when water temperatures are cold.
