The main attraction here is a dangerous Blue-Maned Lynel that patrols the area. The Lynel here wields a Savage Lynel Sword, Savage Lynel Shield, and a Savage Lynel Bow. The lynel protects some ruins found just to the south, where there are two treasure chests. Both of which contain Gold Rupees.
At the west side of the headland there is a Lizalfos camp, with Green Lizalfos, Blue Lizalfos, and more dangerous Black Lizalfos. Once defeated, Link can open the treasure chest to find five Ice Arrows.
There are a trio of Korok Seeds that can be found on the headland. One is on a lower elevation at the west side of the area. Link can remove a stone slab by using Stasis to find a small rock where the Korok is hiding. At the north end of the headland, there is a small mountain peak. In the path beneath it, Link can pop a balloon to get a Korok Seed. A third can be found on the higher elevation at the east side of the headland. Collect a series of flowers along the ridge as it heads downhill to get the Korok.
