Mount Whitney(edit)

Approximately 10.5 miles from Portal, 7,776' gain, 1,960' loss, starts at 8,365'. Vigorous high-altitude hike. This is a hike of a lifetime.  It is difficult due to the altitude and requires conditioning and determination.  Should use GPS as some surfaces of the trail are difficult to follow due to massive granite surface area.  Know your water sources and use them wisely.  Water should be treated.  Carry out own waste.  The only toilets are near the parking lot at the beginning. Help others on the trail.  This hike is no joke.  It can be quite dangerous and many hikers have lost their lives on this hike.  Enjoy it and don't become a statitistic.  Once on the summit, rest, take photos and take leisure hike down.  Don't forget to rest occassionally.  Going down is quite easy to trip and fall.  Especially when you are tired.  Try to finish before sunset.
