ROUTE 1

(USFS Adventure Pass required)
Distance: 18 miles round trip on trail and cross-country
Gain: 4200' total, 3600' out plus 600' on return
Time: 8-10 hours round trip
Rating: Class 1, strenuous
Navigation: Easy

DRIVING ROUTE 1

  • Take I-10 east past San Bernardino to the Orange Street exit (SR 38).
  • Go one block east, then go north (left) 0.5 mile to Lugonia Avenue. Turn right on SR 38 (east).
  • Continue east on SR 38 about 33 miles to 1N02, the road to Heart Bar Campground, on the right. Turn right. Note your odometer and go as follows:
  • At 1.2 miles, fork. Go right on 1N05. High clearance may be needed from this point.
  • At 2.8 miles, Aspen Grove Trail 2E05 goes west. Alternate parking area. Continue on 1N05.
  • At 6.9 miles, fork. Go right.
  • At 7.2 miles, fork. The Pacific Crest Trail (PCT) crosses the road here. Go right.
  • At 7.6 miles, fork. Go right.
  • At 7.7 miles, Fish Creek Trailhead (1W07). Park here.

HIKING ROUTE 1

  • From the parking area (8040'), hike trail 1W07 southwest about 1/2 mile to a junction with the Aspen Grove Trail.
  • Keep left on 1W07 and continue, passing Fish Creek Camp, 4 miles to Fish Creek Saddle at 9805'.
  • Follow the trail for a mile plus to Mine Shaft Saddle (9960'), where it joins the trail from Dry Lake (1E05). Turn left and follow the Sky High Trail (1E07). A sign indicates "San Gorgonio 3 1/2 miles".
  • The trail switchbacks up the eastern and southern flanks of San Gorgonio Mountain.
  • Past the top of the switchbacks, the trail heads west and the long hogback of Bighorn becomes clearly visible nearby on the your left (south).
  • Shortly the Tarn, a wide flat area almost free of vegetation, will also become visible as a depression between you and the peak. Descend south from the trail into the Tarn at a point near the western end of Bighorn's hogback. This is most easily done at around 11,100' where a gully (UTM 166727) has been swept relatively clear of brush.
  • Cross the center of the Tarn toward a minor saddle on the west end of the mountain.
  • Ascend a steep trail southeast to the top of the ridge and continue about 1/4 mile to the summit.

ROUTE 2

From Dragons Head
(USFS Adventure Pass required)
Distance: 1 mile one way cross-country
Gain: 400'
Time: 1 hour one way
Rating: Class 1, strenuous with Dragons Head

Original: Joe Young, January 2000

DRIVING ROUTE 2

HIKING ROUTE 2

  • From the summit of Dragons Head, hike down the north-northeast ridge to the saddle.
  • Hike east about half way across the Tarn and proceed to the summit of Bighorn as in Route 1.

ALTERNATE ROUTES

Significant dirt road driving can be saved by hiking from the Aspen Grove Trailhead on 2E05. This saves about 10 miles of dirt road driving, while adding 3 miles and 400' gain to the round trip. It can also be hiked from several other trailheads near the San Gorgonio Wilderness.

From the summit of San Gorgonio Mountain, hike down the Sky High Trail, then south to the Tarn and proceed as in Route 1.

One may leave the Vivian Creek Trail just north of elevation 10,131' and contour northeasterly, crossing the main wash, then proceeding easterly up another wash to the saddle at 10,640'. This reduces the gain to 5000' including 100' on return and the distance to 14 miles round trip.


SPECIAL CONDITIONS

Wilderness permits are required for all routes. They are issued at Mill Creek Ranger Station, 9 miles east of Redlands on SR 38. Day use permits are self-issue on the day of the hike or by mail. Overnight permits must be acquired in person or by mail.
