|Gold Dust x3 | 4000 Gald | Silver Coat | Sir Meows-a-Lot | Geode | 7700 Gald|
As you enter the highroad head directly north to the north wall and then hug it as you run east to find a hold with Gold Dust x3 and then exit and head back to the entrance. This time head east and hug the wall to find another hole with 4000 Gald about halfway up, just before the wall turns straight north.
In the Central Region head southwest all the way to the corner to find a hole on the other side of small pond that has a Silver Coat inside and then backtrack and head north. As you head north you'll come to two small ledge on the east and west sides of the area, but only the west one has anything of interest. Climb up the small ledge and check the center of the north wall to find a hole with Sir Meows-a-Lot and then exit northeast.
The south exit in the Northeast Region is a nice shortcut back to Lakutam Seahaven, but with no treasure there it isn't worth investigating unless you want all the shining points. Head northeast into the main area and then head south to the climb to upper level and check the west wall for a hole containing a Geode . Jump back down and run across the map to check the the wall directly east of previous treasure to find another hole with 7700 Gald .
