There are plenty of places to go mountain climbing in the United States, but few are as beautiful - or as treacherous - as California. The Sierra Nevada range is chocked-full of mountains that range from rocky to grassy and from tall to broad, and Mount Williamson is the second highest of them all.

Standing at an elevation of 14,389 feet, most people climb Mount Williamson via the west side route from Shepherd's Pass. Unfortunately, the access routes to Mount Williamson are often closed, and early summer is about the only time this mountain is accessible to the general public.

Many of the mountains I've written about in the past are difficult because of their rocky faces or particularly icy routes toward the summit. Mount Williamson is different, however, in that the ascent isn't particularly treacherous. It is the sheer length of the climb that makes this mountain worth a notch on your belt.

First, the winding, forest-flanked trail that leads to the mountain is just over 11 miles long, which means that many climbers are exhausted by the time they even begin their ascent. The trip up gains about 8,000 feet total, which decreases oxygen supply and really puts pressure on those leg muscles. It isn't for the faint of heart.

You'll also have to make it across the treacherous Williamson Bowl, which is carved by numerous glaciers that remain difficult to traverse through the late spring. The mountainside itself will seem like a picnic after what you endured to make it there, but always remember that you have to go back after you've descended the mountain.

Since much of your climb to and up Mount Williamson will not be shaded by trees or other vegetation, sun exposure is an important consideration. Make sure that you bring sufficient sun block for your entire party, and you might want to bring a wide-brimmed hat to protect your face from sun and wind.

The Ugg Crochet Cowboy Hat is an excellent choice for women, while the Greg Norman Straw Hat is a great pick for men.

You'll also want to bring along a tent and a sleeping bag for camping at Anvil, and an ice pick or axe if you plant to be climbing during the early part of the year.
