Given the length and difficulty, essential items include plenty of water (more than you think you'll need, as there's no water on the trail), high-energy snacks, sun protection (hat, sunscreen, sunglasses), sturdy hiking boots, a map or GPS device, and a headlamp if there's any chance of finishing after dark. Dress in layers suitable for desert conditions.

Many hikers prefer starting from Tom's Thumb Trailhead in the north. This allows you to tackle the steepest and most demanding ascent early in the hike, getting the significant elevation gain out of the way while you're freshest. The latter part of the hike might then offer a more gradual descent, though some sections near Adero Canyon can have city views and construction noise.
