The Stuart-Trembleur-Takla Lake boating system is located in north central British Columbia and comprises nearly 300 km of waterway. These long, narrow lakes are among the region's most significant recreational features.

The lakes offer great sports fishing opportunities for rainbow and lake trout, burbot, kokanee, and mountain whitefish. The chain is also part of the longest migration route of chinook and sockeye salmon in British Columbia. With more than 630 km of lakeshore to explore, few developed facilities, and sparse levels of use, this chain of lakes provides a remote wilderness experience. A series of small parks have been established along the system providing protected anchorages or attractive beaches. No facilities have been developed at these sites.

Stuart Lake, one of the largest lakes in the province at 90 km long, is the southernmost lake of the chain. The community of Fort St. James is located on the southeast end of the lake. The main body of the lake is between 6 to 10 km wide and is road accessible at many locations. The northwest arm of the lake is narrower, has limited road access, and more of a wilderness feel. This portion of the lake is very scenic with numerous bays, points, and islands. There are four marine park sites on Stuart Lake and two provincial campgrounds.

The Tachie River connects Stuart Lake to Trembleur Lake. The 26 km of river can be a challenge to navigate with fast water and small rapids. Trembleur Lake is almost 50 km long. It has an irregular shoreline with sheltered bays and coves, and a scenic wilderness setting. There is one marine park site on Trembleur Lake.

The Middle River flows from Takla Lake into Trembleur Lake. The river, designated as a Provincial Heritage River, is 22 km long and navigable. At 96 km in length, Takla is the fifth largest lake in the province. Almost 250 km of undisturbed shoreline with sandy beaches and isolated bays are available to explore. There are three marine park sites on Takla Lake. There is sporadic road access on the east side of the lake.

Limited facilities are available at the village of Takla Landing which is located 40 km north of Takla Narrows.

Takla Lake Marine Provincial Park consists of three sites on Takla Lake protected as part of the Stuart-Trembleur-Takla Lakes boating system. These sites provide no facilities but may offer protected anchorages or sandy beaches.

From the mouth of the Middle River at the south end, the 'Y' shaped lake is nearly 100 km in length, making it one of the largest lakes in the province. The Northwest Arm is 40 km long; the maximum depth of Takla Lake is 287 metres. Almost 250 km of undisturbed shoreline with sandy beaches and isolated bays are available to explore. Wildlife viewing, boating, hunting, and angling are popular pursuits in the area. There is sporadic road access on the east side of the lake.
