From Pakliū, the trail travels up and away from the verdant hillsides of Kaupo Gap towards the alpine desert of the crater valley. Within the first mile the trail crosses several patches of smooth, wave-like pahoehoe (pronounced ‘paw-hoey-hoey’) lava as it weaves through the subalpine shrubland. This provides a distinct contrast to the sharp, craggy A’a lava fields that otherwise the trail, particularly on the approach to Holua. The landscape becomes progressively more barren, with the surrounding grasses and shrubs eventually replaced by rock and sand above the tree-line.

Cinder cones rise up the crater floor in this otherworldly landscape. The vibrant colors of Pele's Paint Pot – a multi-hued cone of reds, ochers, and yellows – provide a scenic photo-op with the ridges of the summit present in the background. Kawilinau, or the 'Bottomless Pit', a fenced off volcanic pit 60-70 ft deep, delivers another natural wonder to explore. Endemic Haleakala silverswords can be found along the Silversword Loop, which splits from and then rejoins the main trail; both routes are the same length.

Despite the lack of trail blazes, the path is well defined, easy to follow, and major trail intersections are marked.
