Undvik is south of Spikerogg, and will require some sailing to reach, as there's no signpost for you to just travel to. Shame. That being the case, you'll have to sail there (or swim), and there's no good reason not to score all the treasure along the way.
Hidden Treasure (Level 13)
The first treasure you'll find is just south-east off the coast of Hov, where you'll find a Hidden Treasure event, the area around which is patrolled by a flock of Sirines (level thirteen). You can reach this area by picking your way carefully down the cliffs from Hov, then swimming, or by recovering the boat from near Svolag and piloting it south-east. In any event, when you get there, kill the Sirines in the water, then explore the center of the search area to find a thoroughly rotten, overturned shipwreck. Swim south-west from the center of the search area to find a chest, which is the object of this hidden treasure event.
Smugglers Cache (Level 10)
Return to Svorlag and claim the boat there, if you haven't already, then sail south and slightly west of the last Hidden Treasure event to find a Smuggler's Cache. Yep. There's going to be more of these. Dive in near the search area and kill some Drowned Dead (level ten), then loot three chests.
Smugglers Cache (Level 13)
Time for some zig-zagging, and unfortunately, the layout of these areas makes some back-tracking inevitable. Sail to the south-west to find another Smuggler's Cache event, which is almost due south of the "Old Watchtower" signpost. Dive into the water, kill some Sirines (level thirteen) then loot some chests.
Smugglers Cache (Level 16)
Sail back east to find a small island north of a larger island - this island is south-east of the Smuggler's Cache event guarded by Drowned Dead. Make your way to the north-eastern edge of this island to find yet another Smuggler's Cache event, this one protected by some Ekhidna (level sixteen). Loot the submerged chests, then make your way onto the small island, killing any lingering Ekhidna. Search the south-western part of the island, just north of a precipice, to find a circular container with some choice loot inside. There's also a skeleton to the north, but it's not quite nearly as lucrative.
Board your boat again and sail to the larger island to the south-west, where, along the north-eastern end of the island you'll find some docks at which you can disembark. There's even another boat here, should your last one be in less than desirable condition. Best of all, you'll find the "Kaer Almhult" signpost! That's the good news, the bad news is that the dock here is crawling with Pirates (levels twelve and fourteen).
Kill the Pirates near the dock, then follow a road to the west, which ultimately leads to the pirate's den. These pirates have done well for themselves, taking over this coastal fortress for themselves. Kill the pirates and their Guard Dogs (level one) then get to looting. There are plenty of parcels lying around, but the lion's share of them are to the south-east. Once that's done, make your way to the western edge of the L-shaped castle and go some stairs just north of an over-turned wagon. At the top of the stairs, turn east to find a chest sitting near some rubble, wherein you'll find the "Diagram: Ursine Steel Sword - Enhanced" .
Head back downstairs, then explore the north-western corner of the castle grounds, where you'll find a collapsed wall leading to a square tower. Leap over the short wall, drop down a ledge, then head down some stairs to the south to reach a tunnel. The above-ground parts of the castle might not be in great shape, but the subterranean bits still seem intact, and the pirates have clearly taken advantage of this fact.
Kill any pirates that get in your way, then plunder your way south-east until the hallway turns east, where more pirates lurk. On the body of one of them you'll find a "Mysterious Note" , which talks about some "Ancient One" these pirates are apparently sacrificing to. Why is the name "Cthulhu" in the gibberish language at the bottom of the note? Oh well. Loot some parcels to the east, then go through a doorway to the south to find the Pirate Leader (level fourteen) who is stronger than his level suggests.
In the torture chamber the Pirate Leader occupied you'll find a "Key to Prison" on some planks to the west. Grab it, then head back west down the hallway and open the other two doors to the south, which you can now open. In the eastern of the two sky cells you'll find a corpse you can investigate, round container full of goodies. As nice as that is, in the western-most sky cell you'll find no fewer than three chests - a fine reward for clearing the vermin off this island.
Smugglers Cache(s) (Levels 13 and 18)
You're now done with this island, so climb back to the surface, leave the fort and return to your boat - presumably moored at the docks. Sail to the south-west to find a Smuggler's Cache near which some Sirines (level thirteen) prowl. To the north-west you'll find another Smuggler's Cache event, this one guarded by some Drowned Dead (level eighteen).
Spoils of War (Level 18)
Now turn your attention to the west, where you'll find two islands near each other, with the south-eastern one being larger than the north-western one. Sail west and pilot your ship between the two islands to find a boat moored along the north-western coast of the south-eastern island, on the shore of which you'll find "The Pali Gap Coast" signpost. You need not worry about this area too much, yet, as there's nothing you can do here right now.
You can, however, continue to sail south-west to find a Spoils of War event, which superficially looks like any of the Smuggler's Caches you've been doing. Don't be distracted by the debris floating on the surface of the water, however, and dive at the search area. Kill a few Drowned Dead (level eighteen), then swim to the sea floor to find a shorn ship. Just to the west of the center of the search area you'll find a chest, which is the object of this event.
Spoils of War (Level 13)
Get back on your boat and sail south-west to another island, where you'll find another Spoils of War even along the south-eastern coast of this island. Stop your boat near a shipwreck patrolled by Sirines (level thirteen) and kill the pests, then swim to the wreck (the prow and mast are easy to spot sticking out of the water). Dive down and loot two corpses near the wreck, three chests under the wreck, and another chest and a parcel on the submerged part of the deck.
Smugglers Cache(s) (Level 16)
Time for the big back-track. Sail your way back to the island upon which Kaer Almhult stands and from there sail south, past the first Smuggler's Cache to the south-west to find another Smuggler's Cache. Here you'll find Ekhidna (level sixteen) guarding the underwater chests. Loot them, then sail to the south-east to find another Smuggler's Cache event.
Only one more bit of loot to get. From the last Smuggler's Cache even sail south-west to find an island. You can land on the north-eastern coast of this island, upon which many shipwrecks loom. You'll also find two Foglets (level twenty-six) prowling around here. Cut them down, then make your way to the south-western coast of the island, which is a very short walk, considering the size of the island. Once along the south-western coast, walk north-west to find another shipwreck beyond (north-west) of which is an icicle-adorned cave. Swim on in there to find an ornate chest which contains the "Diagram: Enhanced Ursine Trousers" .
With that, you're done scouring the sea for treasure... at least, the sea between Spikerogg and Undvik.
