This Douglas fir is 74 metres tall. Nothing else in Portland comes close. The city register measures it at 243 feet, or 74.1 metres, with a trunk 5.58 metres around and 1.78 metres through. A student piece in the PSU Vanguard, working independently, arrived at exactly the same height and girth, which is reassuring for a measurement that is genuinely hard to take on a tree this size standing in a steep ravine. It grows at the bottom of the Balch Creek canyon in Forest Park, one of the largest urban forest reserves in the United States, on the Lower Macleay spur trail about a hundred yards past the stone house ruin that everyone here calls the Witch's Castle. A large stone beside the path marks it. Look up rather than around: at this height the top of the tree is well outside anything you can take in from the trail. No age is recorded anywhere, and that is not an oversight. This is not a planted landscape tree with a date attached to it but a survivor in a patch of regrown native forest, and nobody has cored it. The ravine explains the height. Steep, shaded, wet, sheltered from the wind, and never quite worth the trouble of logging.
Lower Macleay Park / Balch Creek spur trail, near NW Cornell Rd, Forest ParkYou can recognise it by a large stone marking it beside the trail, and by looking straight up, since it is Portland's tallest tree by far. It stands on the Lower Macleay spur trail, past the Witch's Castle ruin.
Free, always open. Standing on Portland Parks & Recreation land inside Forest Park/Macleay Park, on the Lower Macleay spur trail about 100 yards from the stone house ('Witch's Castle') ruin along Balch Creek. Reached on foot via a public park trail, not roadside.
Access via the Lower Macleay trailhead, 2960 NW Upshur St; TriMet bus lines 15, 26 and 77 stop within a few blocks (NW Thurman/27th-29th or NW Vaughn/27th), then it is roughly a 15-20 minute walk up the Lower Macleay/Wildwood Trail along Balch Creek to reach the tree.
