The Green Lake Loop is the original trail that runs around the back side of Green Lake.  Before the Sea to Sky Highway was cut through the valley in 1964, the road for vehicles went through a treacherous route on the opposite side of Green Lake.  With the Sea to Sky Highway open for cars, the old road behind Green Lake became the trail known as the Green Lake Loop.  The Green Lake Loop stretches a windy and often steep 6 kilometre arc up around Green Lake and emerges from the forest 30 metres to the left of Wedge Creek bridge.

Wedge Creek cuts through the valley that separates Wedge Mountain and Blackcomb Mountain and empties into Green River near the north end of Green Lake.  Wedge Creek is notable for the mountain pass between Wedge and Blackcomb that runs between it and Billygoat Creek. The original name for the pass, officially adopted in 1930 was Wedgemount Pass, however it was changed in 1957 to Wedge Pass to avoid confusion with nearby Wedgemount Creek which flows from Wedgemount Lake.
