(possible minor pre-sear 'exploration' Spoiler info ahead...)
The area isn't large and for some reason is free of critters and loot. We thought at least there should be a chest in there... heck maybe we missed something. I do know I don't have a pre-sear character / any char slots free to go back there anytime soon. Anyways here is a screenshot.
The area is in Regent Valley and if you leave Fort Ranik, pass the apple NPC lady, keep to your right (compass directions elude me), keep walking and head to the waters edge, cross the water (not sure if you have to go straight across or angle a bit) and find the entry behind some trees along the rock wall. Unfortunately the area is not acessable post-sear. :/ It IS however a very interesting and cool looking place.
