TL;DR
Combine both if you have 5 days or more. Otherwise, answer these 3 questions:
- Are you looking for the "paradise" effect (Maya Bay, turquoise water)? → Koh Phi Phi
- Do you want more choice of hotels + land activities + facilities? → Krabi
- Are you traveling with children < 8 years old or have a medical need? → Krabi (Ao Nang)
Koh Phi Phi — the mythical island
Advantages
- Maya Bay, Pileh Lagoon, Bamboo Island — Thailand's most photographed beaches are here
- Island atmosphere — no cars, only longtail, night market
- Snorkeling and diving — crystal clear waters, reef accessible from the beach
- Tonsai nightlife — beach bars, fire shows, backpacker/couple atmosphere
Boundaries
- Boat access only — ferry 2 hours from Phuket or Krabi
- Few roads (especially pedestrian paths)
- Basic medical infrastructure — no hospitals, just clinics
- Expensive hotels of equal quality (island logistics)
- Noisy Tonsai — if you sleep badly next to bars, avoid
- Maya Bay strictly regulated (no anchorage, entry fee, opening times)
For whom
- Couples on romantic weekend/honeymoon
- Solo or duo backpackers
- Divers
- Travelers who want 1 wow instagram per day
Krabi — the smart continent
Advantages
- Railay — peninsula accessible by boat, climbing cliffs, sublime beach
- Ao Nang — convenient base, lots of hotels, restaurants, agencies
- Hong Islands, 4 Islands Tour — magnificent day trips
- Kayak mangroves Ao Thalane — nature option excluding mass tourism
- Tiger Cave Temple + caves — varied land activities
- Krabi Airport — direct flights from Bangkok, no need to transit through Phuket
- Complete infrastructure — hospitals, shopping centers, pharmacies
Boundaries
- Less "pure postcard" — the Krabi beaches are beautiful but Maya Bay remains unique
- Ao Nang can be a “seaside resort” — shopping streets, a bit of Benidorm
- Railay without Maya Bay — you see less of the iconic pure southern Thailand
For whom
- Families with young children
- Travelers who want a stable base for 5-7 nights
- Climbing enthusiasts (Railay is world-class)
- Travelers with a higher budget (more 4-5* resorts)
