This is a tiny little island off Kaoshiung that can be reached by a 5 minute ferry costing NT$15. The ferry is very frequent so it's well worth a visit. The island has forts, beaches, markets etc. I only had 1 hour on the island and wished that I had half a day to explore it properly. I recommend hiring a push bike and riding around the island. If it's beach weather, remember to pack swimmers! Also, apparently a very popular spot for sunset, but get there a bit earlier, as the lines to the ferry starts to get big around sunset time.
