Island Lake Waterfall Hike Description
This is a great little hike to explore the Island Lake environs. The hike starts from at the unmarked junction at the southeast end of Island Lake (10,346-ft.). The trail to the left (northwest) leads to campsites along the lake’s southwestern shore. The path straight ahead (northeast) is the Indian Pass trail.
Follow the Indian Pass trail as it skirts the eastern shore of Island Lake. Along the way enjoy fine views of the summits towering above Titcomb Basin to the north. Elbow (11,948-ft.) and Sky Pilot (12,129-ft.) peaks rise in the distance to the northwest.
Pass an unmarked trail/route at 0.3 miles climbing to Pass 11,120, a saddle on the ridge between the Island and Wall Lake basins. Soon our trail curves to the left (north/northwest) around the northeast end of the lake and starts climbing.
At 0.7 miles the path curves to the right northeast and ascends the north side of a draw to a saddle on a low ridge at 0.9 miles. Atop the ridge are more great views of the summits of Titcomb Basin.
The trail now descends through meadows into the pretty basin cradling Lake 10,467. As you descend look for a use trail traveling along the lake’s southeastern shore. At 1.1 miles bear left on a spur trail that descends toward the lake shore and then turn left on the use trail skirting the lakes southeastern shore. Soon views open to a waterfall on the inlet stream on the north side of the lake. This is the stream draining Titcomb Basin.
Reach the south end of Lake 10,467 at 1.4 miles. Here a waterslide spills over polished slabs into a small unnamed lake. A brief descent leads to the lake shore. The trail now continues heading southwest, leaving the lake shore to circumvent rock outcroppings. Island Lake is now in view.
At 1.5 miles the trail reaches to top of a waterfall that plunges 60-feet down a rocky slope into the northeastern side of Island Lake. The trail now descends steeply through meadows along the east side of the falls to a viewpoint at the bottom of the beautiful cascade.
When you are done admiring the falls you have two options. Retrace your steps on continue along the loop, which involves some route finding. To continue the loop, follow a use trail that heads southeast along the lake shore. Views open to Mt. Lester (12,342-ft.) and a number of unnamed peaks rising above the eastern end of Island Lake.
Soon you will reach a low rocky knoll with steep cliffs blocking further travel along the shore. Here the trail climbs through willows and then brushy foliage to a saddle atop a knoll. The use trail fades and is difficult to follow as it travels through the thick foliage.
Atop the knoll you will see a cliff rising to the east. A talus field extends along the base of the cliff to the lakeshore. You have two options for completing the loop. From the saddle head due east, cross the rock pile and then descends to the lakeshore along the cliff on a trail of sorts. The other option is to descend from the saddle to the lakeshore through meadows to the west of the talus slope and then traverse the boulder field along the lakeshore to the edge of the cliff.
Where the cliff meets that lakeshore you will find a trail traveling through a willow thicket and then emerges on a meadow. After a short traverse through the meadow along the lakeshore the trail curves to the left (east) away from the lake and crosses a small drainage.
On the east side of the drainage the path fades as it climbs through willows. Ahead you will see the continuation of the trail climbing a low hill. Walk cross-country to the continuation of the trail and climb the hill. As you crest the hill the trail again fades but the way is now obvious. Descend through meadows, staying to the north of three small tarns, to the Indian Basin trail at 2.0 miles. Turn right (southeast on the trail) and retrace your steps back to southwest side of Island Lake.
