You're asking a tricky question! "30 degrees N" is a latitude line, not a specific location. It runs across the entire globe, so there are many islands near it!

To give you a more specific answer, I need more information. Can you tell me:

* What longitude are you interested in? For example, 30 degrees N, 90 degrees W is a different location than 30 degrees N, 0 degrees.

* Are you interested in a specific country or region? For example, "an island near 30 degrees N in the Caribbean" is a more focused question.

Once you give me more detail, I can help you find the island you're looking for!
