Both destinations are popular choices for travellers. Koh Phi Phi is an island group in the Andaman sea with lots of gorgeous islands and beaches to explore. In the night, the central area of Koh Phi Phi Don turns into a party haven for backpackers with parties going on till sunrise. The northern part of Koh Phi Phi Don (around Laem Tong Pie) is more secluded and lets you enjoy the more tranquil side of Koh Phi Phi. Krabi is a perfect balance of the two. Along the coastline, you'll find stunning beaches bordered by high limestone cliffs. You can visit several of these beaches without having to leave the mainland, but you can also book a boat trip to explore nearby islands or more remote beaches.
