ROUTE 1

(USFS Adventure Pass may be required)
Distance: 11 miles round trip on road and trail
Gain: 2400 '
Time: 4-5 hours round trip
Rating: Class 1, moderate

Original: Warren E. von Pertz, July 1969

DRIVING ROUTE 1

  • Take the 210 freeway east to Baseline Road exit in the City of Claremont. Turn left (west) at the bottom of the off-ramp onto Baseline Road.
  • Almost immediately, take the first right (north) onto Padua Ave.
  • Go 1.8 miles north on Padua to the intersection with Mount Baldy Rd. Turn right (northeast).
  • Take this road northeast and then north about seven miles to Mt. Baldy Village.
  • Continue another four miles to the intersection with San Antonio Falls Road on the left (gated). Park here.

Note: There is a good parking lot for ridesharing in this area. To get there, after turning west on Baseline Road, continue past Padua Avenue a short distance to Mills Avenue. Turn north on Mills, and continue to Mt. Baldy Road. The parking lot is at the northeast corner of this intersection.

HIKING ROUTE 1

  • From the parking area (6160'), pass the gate and hike up the road to Baldy Notch at the top of the ski lift.
  • Turn right (southeast) and follow a road up to the summit.

SPECIAL CONDITIONS

Do not hike up the slope beneath the ski lift. This is not legal.

NOTE

The ski lift at the end of Baldy Road operates in the summer months on weekends and some holidays. It is possible to take this (for a fee) to Baldy Notch. This significantly reduces the gain and distance. A popular trip is to take the lift to the notch, then climb Thunder Mountain, Telegraph Peak, and Timber Mountain, returning via Icehouse Canyon to the site of the old Ice House Resort. This requires a car shuttle.
