Haiwee Reservoir was once a meadow inhabited by pidgeons that the Piute Indians called "Haiwai" their word for "dove".
This is a fun half day class 2-3 scramble with outstanding views of the southern Sierra scarp especially Olancha Peak and also Haiwee Reservoir below.
The first 1.5 miles are paved the rest is dirt. Go 7.2 miles from Hwy 395 and take the right fork (main road) 2.4 miles to a smaller road going south. Turn right and go another 2.5 miles to a dirt track road heading west then south to the saddle (4,993') and park. Walk up .6 miles west to another saddle south of the ridge and hike a mile (with some scrambling) to the peak.
This is about 1,000' gain and less than 4 miles round trip.
2 wheel drive high clearance recomended but I found this last 2.5 mile section sketchy with sand in the high clearance van and decided to park about a mile back from the saddle and go straight up the steep east slope then south to the summit which was a fun route with 1,100 ' gain and less than 2 miles round trip.
Haiwee Reservoir itself has been closed to the public as of 2005.
