In an old guide, there is a description of a trail, and the only access to Lizard Head, from Middle Spire. That trail no longer exists, and the current (2020) access is via an old logging road / log landing / campsite that is a half kilometer above, to the north of, the regular Phantom Spires parking. There is a good parking spot about 100m to the NE of the bottom of this old road. One walks up the old road, to the campsite, and at the back, SW, end of the flat area, wander west, towards Lizard Head, on an easily followed trail. After scrambling on a few meters of rocks, the trail turns right and starts up somewhat of a ravine. Scarcely 15m up this "ravine", cairns to the left mark the access to Lizard Head.
Of note, the base of Lizard Head, in early 2020, was quite overgrown and not much fun around the SE base where the Lounge Lizard route is. The NW corner, and the route Dewlap, is open.
