Away from the crowds for CNY?

Anyone have suggestions for where my gf anf I could go in Taiwan this Chinese New Year (next week); a place that is scenic but not full 'o people?

We’ll be down in southern Taiwan anyway so we’re thinking about Lanyu (Orchid Island) although it may be a bit cold and rainy. Kenting is surely going to be packed.

Thanks!

PS: Are there any flights from Kaohsiung to Lanyu, or are they all from Taidong?
