Nine miles south of the village of Estes Park, split by the boundary
line of the national park, rises the precipitous, picturesque, and very
craggy mountain called the "Twin Sisters", on which the park maintains a
fire lookout. Its elevation is 2,400 feet above the valley floor, which
is about 9,000 feet high. The trail leads by many zigzags to a peak from
which appears the finest view by far of Longs Peak and its guardians,
Mount Meeker and Mount Lady Washington.
From the summit of the Twin Sisters an impressive view is also had of
the foothills east of the park, with glimpses beyond of the great plains
of eastern Colorado and many of their irrigating reservoirs.
