Notes: Stratosphere Giant is the world's 4th tallest tree, the tallest and 4th largest tree in Humboldt Redwoods State Park, and the tallest and largest tree on Calf Creek Flat. It held the title of world's tallest tree until naturalists Chris K. Atkins and Michael W. Taylor discovered Helios in Redwood National Park on July 1, 2006.

A kiosk in the Thomas H. Kuchel Visitor Center near Orick displays a 360-degree panorama of Bull Creek Flat taken from the top of Stratosphere Giant. Humboldt State University forestry professor Stephen C. Sillett published another view from the treetop and photographed the crown from a nearby tree. National Geographic photographer James Balog published a composite photograph of Stratosphere Giant.

Drive: Stratosphere Giant is 196 mi (315 km) north of San Francisco near the community of Weott.

Northbound: From U.S. Highway 101 just north of Weott, take exit 663 South Fork Honeydew and turn left onto California State Route 254 (Avenue of the Giants). Turn left under the bridge onto Bull Creek/Mattole Road.

Southbound: From U.S. Highway 101 just north of Weott, take exit 663 South Fork Honeydew and turn right onto Bull Creek/Mattole Road.

Drive west 3.4 mi (5.5 km) on Bull Creek/Mattole Road to the Calf Creek parking area, on your right, near a small Calf Creek sign. Immediately across the street, to your left, is a Bull Creek State Wilderness sign.

Hike: GPS-assisted navigation is recommended for this hike. Though you may be tempted to walk straight to Stratosphere Giant from the parking area, the direct route is not ideal because a fortress of huge, fallen trees surrounding Stratosphere Giant to the north, west, and east blocks your path. Instead, take the Big Tree Trail around Calf Creek Flat to approach Stratosphere Giant from the south. This route is more accessible and requires less off-trail hiking.

To get to Big Tree Trail, walk west 600 ft (183 m) on Bull Creek/Mattole Road from the parking area to a turnout on the left/south side of the road. Near the far end of the turnout, you will see a small sign which reads Trail - No dogs except service dogs. This sign marks the connection to Big Tree Trail which turns left/south and follows Bull Creek.

Hike south on Big Tree Trail. In 0.3 mi (0.5 km), the trail passes under a fallen tree and turns right/south along Bull Creek. After you pass under the fallen tree, leave the trail and, using a GPS device, continue straight through the forest. You will soon see a cut log about 100 ft (30 m) away. Continue through the cut log and head northeast 400 ft (122 m) off-trail to Stratosphere Giant. After visiting Stratosphere Giant, hike east 500 ft (152 m) off-trail to Idril.

Rating: Easy One-Way Distance: 0.5 mi (0.8 km) Ascent: 22 ft (7 m)
Time: 11 min Off-Trail: 600 ft (183 m) Descent: 63 ft (19 m)
