From the Lake Boomerang outflow continue down the true right of Gorge Burn. Vegetation is thick, boggy, bouldery and windfallen and progress is slow with few deer trails at first.
Grassy flats at the head of Lake Cecil provide opportunities to camp.
The shores of Lake Cecil are steep and/or boggy and it is advisable to climb onto the terrace south of the lake, descending to the mouth of the creek entering the lake from the south where a boggy crossing is required. The remaining shore can be sidled 10-20m above the lake.
Continue down the lower valley sidling the southern valleyside negotiating a series of debris dams as you progress downstream. As the river begins to gorge out 1.5km from the lake, deer trails begin to appear, sidling at about 440m onto the broad terrace leading to pt556. Follow this terrace, climbing slightly. Drop NE down the spur 100m prior to reaching pt556. This spur descends parallel to the river, passing the falls 50m or so to their south. There are reasonable deer trails. A cut walking track can be picked up from the falls to the lakeshore at the river mouth.
Lake Boomerang outflow to Lake Cecil head: 1.5km, 1-2 hrs
Lake Cecil head to Gorge River mouth: 4.5km, 3-5 hrs.
