Two days in Krabi: the budget core Krabi is a province on Thailand’s Andaman coast, not one beach town, and two days is enough to see why that distinction matters. Base cheap in Ao Nang or Krabi Town, cross by longtail boat to Railay (there is no road to it, in any season), then spend your second day on a shared island boat trip. The Nov-Apr dry season gives you calmer seas and a much better chance of both boat days actually running; the May-Oct monsoon can delay or cancel them.

Five days in Krabi: the budget spine, extended Krabi is a province on Thailand’s Andaman coast, not one beach town, and five days gives you room to move past the highlight reel into inland, lower-cost territory too. Base cheap in Ao Nang or Krabi Town, cross by longtail to Railay (there is no road to it, in any season), take one paid island day, then spend the extra days this length buys on an inland loop and a Phi Phi trip.

Six days in Krabi: the budget spine Krabi is a province on Thailand’s Andaman coast, not one beach town, so pick a cheap base first: Ao Nang for the tour operators and the direct longtail launch, or Krabi Town for lower room and food prices. Six days covers the full budget spine: Railay by longtail, one island day trip, an inland temple-and-pool day, and a Phi Phi or Ko Lanta add-on, weather allowing.

Seven days in Krabi: the full budget spine Krabi is a province on Thailand’s Andaman coast, not one beach town, and seven days is enough to run the entire honest circuit without rushing any single day: Railay, both main boat-island groups, an inland loop, and a Phi Phi overnight, with a spare day left over. Base cheap in Ao Nang or Krabi Town, cross by longtail to Railay (there is no road to it, in any season), and build the two island days and the Phi Phi crossing around the forecast rather than a fixed date.

Krabi is a province on Thailand’s Andaman coast, not one beach town, and that matters if you’re counting baht. Base in Ao Nang for the shortest boat rides and the highest prices, or Krabi Town for local rates and the region’s bus and ferry hub. Railay, the karst-walled peninsula everyone wants to see, has no road in from either base, in any season, you cross by shared longtail for roughly 100 baht.

Krabi is a province on Thailand’s Andaman coast, not one beach town, and that changes the budget math. Base in Krabi Town for the lowest prices or Ao Nang for the shortest boat rides; either way, the karst-cliff beaches at Railay have no road access, in any season, you cross by longtail for roughly 100 baht. Most of what actually makes Krabi worth visiting costs nothing: Ao Nang, Nopparat Thara and Phra Nang Cave Beach are all free once you’re standing on the sand.
