Mount San Antonio is the third tallest peak in southern California. At an elevation of 3,066m (10,060′) this summit truly rewards the peak bagger with 360º panoramas and a well earned rest at the top of your world.

Hike Details:

DIFFICULTY: Moderate to Difficult
DISTANCE: ~ Between 12k – 19k (8-12 miles) (RT)
TIME: ~ 5-7 hours

Parking fills up early on the weekends. If the parking area is full, there’s usually roadside parking all the way up and down the road.
A large parking lot up by the ski lifts is usually wide open in the summertime. Park up there, and walk 10 minutes back down to the trailhead. (theres a secret hiker trail on the left that saves 5 mins… shhhh)

Pack List:

 

Capacity/Size:

Water:
– 1.5 liters
– Bring an EMPTY 1 liter bottle (like a Nalgene) or bladder (like a Platypus) which we will filter/fill at the spring half way up at the Ski Hut.

– A 32oz bottle of gatorade (full sugar) can take care of most your water and glucose needs. It’s just extra weight to bring from the bottom.

We will refill all the empty bottles at the spring and will carry the heaviest water load from there to the summit. This will give us enough for the complete descent regardless of our descent route.

Other Notes:

 

Parking requires a National Forest Adventure Pass.
$5 for a day pass (these can be picked up at the Mt. Baldy Visitors Center in town)
$30 for an annual pass (these can be purchased on-line, in town at the visitors center, at REI, at Adventure 16, Dick’s Sporting Goods, and most sporting goods stores in southern California)

If you’re new to this mountain, it’s best to go with a guide or someone who is quite familiar with all of the trails. Lots of people get lost on these trails at all times of the year, and need rescue. Always be prepared to spend the night on the mountain. If unsure of the trail, ask people. Carry a map or GPS and be familiar with how to use them.

This is an alpine area and can be quite taxing even on the fittest of people. Altitude sickness can effect anyone at any any time at these elevations. If you are not feeling well on this hike, plan on bailing. Head down to lower elevations. Don’t worry, the mountain will be here next time.

On the weekends, Parking fills up pretty quick at the trailhead. If you arrive at the trailhead at 9am, you might be out of luck, however, theres usually more parking up the hill a bit further at the Baldy Ski Lifts. You just have to walk an extra 10 minutes downhill to the trailhead.

Theres a restroom at the trailhead, and at the Baldy Ski Lifts building

The Baldy Notch (“Top of the Notch” restaurant (7,800’) has a full bar with delicious cold beer on tap and in bottles, as well as a full restaurant to satisfy your post hike hunger and thirst. (they take credit cards too)
