Notes: Iluvatar, also known as Cal-Barrel Giant, is the world's 16th largest tree, the 2nd largest single-stem coast redwood, and the largest tree in Prairie Creek Redwoods State Park. Humboldt State University forestry professor Stephen C. Sillett named the tree after J. R. R. Tolkien's Eru Ilúvatar, the supreme deity of Arda.

The crown of Iluvatar, one of the most-complex known, contains 209 reiterated trunks, including the largest known reiterated trunk and the only known Class 6 reiteration (six nested reiterations off the main trunk). It is the largest crown, 915,500 ft3 (25,924 m3), of any redwood yet measured and contains over one billion leaves. The October 2009 issue of National Geographic magazine includes a composite photograph of Iluvatar. The National Geographic Explorer program Climbing Redwood Giants (from 17:02 to 20:12) documents the photograph production.

Drive: Iluvatar is 261 mi (420 km) north of San Francisco near the community of Orick.

From U.S. Highway 101 just north of Orick, take exit 753 Newton B. Drury Scenic Parkway. Drive north 1.5 mi (2.4 km) on Newton B. Drury Scenic Parkway to Cal-Barrel Road. Turn right onto Cal-Barrel Road, drive east 650 ft (198 m), and park just before the road turns left through a gate.
