The Hollow Tree and Meteor Trails
Including Opal Creek and Middle Ridge
Length 8 miles Climbing 1060 feet
This enjoyable loop takes you from the visitor's center to the northern limit of Big Basin's old growth redwoods. The loop features trails through two redwood-filled ravines — the Hollow Tree Trail and the exceptional Meteor Trail. Almost the entire route is in remarkably dense old-growth redwood and tanoak forest, the foliage looking like an immense, solid wall of greenery. The entire route is free of traffic noise, and much of it follows rushing creeks.
The best direction to take the loop is counter-clockwise, which puts the best scenery near the end of the hike. The climbing is also a little easier in this direction.
Start by hiking north on North Escape Road, which runs along Opal Creek. For the first mile, the road passes through some fine old-growth forest, somewhat spoiled by numerous old picnic areas that don't seem to be used any more. After crossing an auto bridge, the narrow road runs through another stretch of impressive old-growth redwoods. Although it's paved, much of the road is covered with redwood needles and is actually more pleasant and scenic than the parallel Skyline-to-the-Sea trail, offering better views of both the redwoods and the creek.
The trail and road remain close together until they reach a hexagonal kiosk (with interpretive displays) next to another automobile bridge. Immediately after the bridge, turn left onto the Skyline-to-the-Sea Trail, which runs along burbling Opal Creek for a mile before reaching the intersection with the Hollow Tree Trail (for a great detour, continue straight on the Skyline-to-the-Sea trail for another quarter-mile. At the second footbridge is a small but scenic cluster of good-sized redwoods sheltered in a narrow ravine).
The Hollow Tree Trail climbs gently at first, then more steeply, though a large ravine. At first the tanoak is so dense that you can't really see many redwoods, but as the trail climbs the woods become gradually more open and more scenic. The redwoods are unusually sparse, and the large spaces between them are mostly filled by tanoak. The ground is littered with fallen light-brown tanoak leaves. There are a few pretty good-sized redwoods to keep the scenery interesting, but most of the redwoods are mid-sized. Most of the trees along the upper half of the trail have been blackened by a forest fire, and there are a few short stretches where the redwoods have been logged. It's not clear which tree, if any, is the hollow tree of the trail's name, but several large trees alongside the trail have been hollowed out by fire.
The creek disappears and the old-growth redwoods give way to logged forest just before the intersection with the Lane-Sunset Rim Trail. Go left, staying on the Hollow Tree Trail, to climb up to Middle Ridge Fire Road. Although it isn't overgrown, the trail is very faint in this area.
Reaching the fire road, the trail briefly breaks out of the forest into warm sunshine, and there are some views of the surrounding hills. It's a nice break from the woods. Middle Ridge Fire Road then descends steeply through old-growth redwoods, offering a few views over the Opal Creek watershed.
The Meteor Trail continues this steep descent, entering a dark, narrow, and lushly-wooded ravine. This trail is the best part of the hike and is by far the most scenic of the many trails on the eastern slope of Middle Ridge. The redwoods are larger and more densely-packed than on the Hollow Tree Trail, and the ground is covered with a thick mat of very dark brown decaying redwood needles.
Like the Hollow Tree Trail, the redwood trunks along the upper half of the Meteor Trail have been blackened by a forest fire. Perhaps because of the fire, this area lacks the usual dense understory of huckleberry and tanoak, so the impressive collection of old-growth redwoods is not hidden from view. Redwood sorrel and ferns line the creek channel. The forest becomes more ordinary-looking near the bottom of the trail; the redwoods seem smaller and a dense understory clogs the views.
For variety, take the Skyline-to-the-Sea trail instead of North Escape Road on the way back to park headquarters. The trail, which can get muddy in winter, passes the now-empty site of a 19th-century homestead. There are few big trees in this area, but it's unclear if that's a result of logging since no stumps are visible.
