Question 1

When is the best time to visit Krabi for scuba diving in Ao Nang and Phi Phi?

Accepted Answer

For most divers, November to April is the sweet spot because seas are calmer and visibility is more consistent, often around {{ 15 | visibility:m }} to {{ 25 | visibility:m }} on good days. December to March is peak season, so boats and hotels fill fast. May to October is the southwest monsoon, which can mean rough crossings and canceled trips, especially to Phi Phi. If you travel in the monsoon, plan flexible dive days, choose nearer sites when needed, and build a strong topside plan for rainy afternoons.

Question 2

How do I get from Krabi Airport to Ao Nang and then to Railay?

Accepted Answer

From Krabi International Airport (KBV), most travelers transfer to Ao Nang by taxi, pre-booked van, or shared shuttle on a {{ 26 | distance:km }} drive. Railay has no road access, so you continue by longtail boat from Ao Nang or Ao Nam Mao pier, usually with a short open-water crossing. If you have bulky dive gear, a private transfer plus a private longtail can be the least stressful option. Arrive with small cash for boats and park fees, and note that late-night arrivals can limit boat availability.

Question 3

Do I need to pay national park fees for Phi Phi, Maya Bay, and Koh Hong trips from Krabi?

Accepted Answer

Often, yes. Many popular Krabi island routes enter national park zones, especially around the Phi Phi Islands and Hong Islands. Fees are commonly charged per day and may be collected in cash by park staff at a pier or by your tour operator on the morning of the trip. Some tickets include fees, others do not, so ask before you book. Maya Bay also has strict protection rules, including a swimming ban and seasonal closures, so confirm current access if your itinerary relies on that stop.

Question 4

What are the best beginner-friendly dives near Ao Nang?

Accepted Answer

Beginners usually do best on the sheltered reefs and sandy training sites near Ao Nang before stepping up to deeper Phi Phi walls. Look for itineraries that include gentler profiles around {{ 5 | distance:m }} to {{ 18 | distance:m }}, with minimal current and easy boat entries. Sites like Koh Ya Wa Sam and calmer Phi Phi reefs are commonly used for Open Water courses and refreshers. Pick an operator that keeps group sizes reasonable, provides clear briefings, and is willing to adjust the plan if conditions change.

Question 5

Where is the best snorkeling near Ao Nang for non-divers?

Accepted Answer

For easy snorkeling, most people join island-hopping tours rather than staying on Ao Nang beach. Koh Poda and Chicken Island are popular because they combine shallow coral, clear-water potential in the dry season, and short boat rides. Koh Hong is ideal if your group wants more scenery and a lagoon feel. Try to snorkel in the morning when seas are calmer, and stay within {{ 1 | distance:m }} to {{ 5 | distance:m }} depths if you are not a confident swimmer. Always avoid standing on coral and keep fins off the reef.

Question 6

Can I freedive in Krabi, and where should I train for depth?

Accepted Answer

Yes. Krabi has freediving instruction and boat-based sessions, especially in the dry season when the surface is calmer. For relaxed training and mixed itineraries, sessions near Koh Hong or other nearby islands can work well. If your priority is depth and consistent conditions, consider a split stay with Koh Lanta, where Koh Haa is often used for clearer water and steeper drop-offs. Whatever your plan, use a float and flag, dive with a trained buddy, and avoid pushing depth when surface chop or current increases.

Question 7

How warm is the water in Krabi, and what wetsuit should I pack?

Accepted Answer

Water temperature is typically around {{ 27 | temperature }} to {{ 30 | temperature }} depending on season and weather. Many divers and snorkelers are comfortable in a rashguard or a 3mm wetsuit, especially for multiple dives a day. If you get cold easily, bring a 5mm or add a hooded vest for longer boat days with wind on deck. In the monsoon, rain and wind can make surface intervals feel cooler even when the water is warm, so a windbreaker and a dry towel can make a big difference.

Question 8

What are the biggest safety concerns for diving and snorkeling around Phi Phi?

Accepted Answer

The two most common issues are boat traffic and changing sea conditions. Phi Phi is busy with longtails and speedboats, so divers should carry an SMB and snorkelers should stay tightly grouped. Currents can run around headlands and channels, and some walls can have surge, especially on spring tides. Follow your guide's plan, avoid overhead environments unless trained, and do not touch limestone or coral. In May to October, prioritize conservative decisions because rough crossings can turn a normal day into a difficult one quickly.

Question 9

How many days should I plan for a Krabi trip that mixes diving, snorkeling, and Railay?

Accepted Answer

Three days is enough for a taste: one Phi Phi dive or snorkel day, one Hong Islands lagoon day, and one Railay beach and viewpoint day. Five to seven days is better if you want multiple dive days plus real rest time. Consider a split itinerary with 3 to 4 nights in Ao Nang for diving logistics, then 2 to 3 nights in Railay for a slower, car-free finish. If Hin Daeng and Hin Muang are priorities, add a Koh Lanta extension and treat it as a separate block.

Question 10

What do I need to know about Thailand entry requirements when flying into Krabi?

Accepted Answer

Thailand entry requirements depend on your passport, but most travelers should plan for a passport with at least six months validity and proof of onward travel. Many nationalities qualify for visa-exempt entry, but allowed stay lengths can change, so verify with a Thai embassy or consulate for your passport. Thailand also uses an online arrival card system (TDAC), which requires you to submit trip and accommodation details in advance following official instructions. Keep confirmations accessible and allow extra time for immigration during peak holiday windows.
