The Observation Platform is a Secret Area in Xenoblade Chronicles. It is located on the upper level of Bionis' Leg. It is accessed by following a narrow path along the edge of a cliff at Daksha Shrine on the lower level, and then going through a cave passage. The Observation Platform gives a good view of the lower level of Bionis' Leg. It is located west of Traveller's Rest.
A level 76 Dark Hox and two level 75 Tempest Vangs are in the tunnel; however, the party can sneak past them. At the Observation Platform itself, the Unique Monster Canyon Valencia can occasionally be seen as it goes along its circuit around Raguel Lake's airspace.
