Beachside Trove is an Unexplored Territory in Xenoblade Chronicles X. It is a cave located on Oblivia's South Coast near FN Site 317 or directly northwest of FN Site 319. The entrance to the cave is hidden behind a large rock pillar. The cave consists of an outer chamber containing one Collectible, and an inner chamber containing 39 more Collectibles and a Treasure Box (Mechanical Level 5). As with all Unexplored Territories, its discovery merits an achievement ("Relaxing at Beachside Trove").
