Best Puzzle Quest?

Most good Zelda quests are a mixture of puzzle solving skills and monster fighting skills.

Can somebody fill me in on some quests that focus primarily on puzzle solving skills?

I'm looking for quests that have many hidden secrets, where you have to follow a series of clues to get to your destination. Basically, I'm looking for the Da Vinci's Code of Zelda quests.

I've given up on caring about graphics or normal Zelda conventions. I'm looking for a good thinker. I'm tired of bombing every wall to find a dungeon. I'd rather solve a riddle to find it.

Anything like that out there?

Try the Isle of Winds or A Link to Tortuga. Or pretty much anything from either of those authors.
