Endgame: I recommend the Howling Caverns boat trip

[Pesky]

Was looking around for things to do after I'd finished the game. I took a different route through the icebergs and stumbled on the Howling Caverns. They're worth a trip, though there's not much to see and nowhere shallow enough to land. The rest of this involves spoilers so don't reveal it unless you've finished all quests and commissions.

To find them, start at the beach south of the West Tower, and paddle your reed boat clockwise around the island. Start as if you're going to the excavation site but instead of pulling into the landing side on the left, carry on taking the path eastward into the icebergs. Once you emerge at the other end you'll see the other way in.

that makes it 3 ways to get into the caverns? First is from beach with father, second down the ropes above and then this one.

I'm am now questioning the name of my route. The trip I recommended does not pass through the starry cave. It is entirely in icebergs. I think perhaps my route is closer to "Ocean's Last Breath" on the map.

I think there are two ways in:
1. by reed boat from Ocean's Last Breath
2. by Zip Trolley into Tiffmoor Gorge
and two ways out:
1. by reed boat
2. using the stairs on the left side if you are looking toward Ocean's Last Breath
