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 about 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 of Thunder Mountain.
- Continue southeast on a trail down into the saddle at the top of Cedar
Canyon and then up to a trail junction at about 8800' just southwest of
the summit of Telegraph Peak.
- Turn left and follow the trail up to the summit.
Do not hike up the slope beneath the ski lift. This is not legal.
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.
trip is to take the lift to the notch, climb Thunder
Mountain, Telegraph Peak, and Timber Mountain, and
return via Icehouse Canyon to the site of the old Ice House Resort. This
requires a car shuttle.
