Horizon Forbidden West [PS4] - Walkthrough Part 25 (Very Hard)

Since entering the Forbidden West area why only one Tallneck is different and can't just directly override like the others (Tallneck is close to the scalding spear) then I suspect there is no other way but maybe by using the air path and after a few main quests, sure enough The Tallneck in question can only be accessed after we can ride or override Sunwing. 1. 01:47.
