Costa Rica has two coasts and they are not versions of each other. Different sand, different water, different culture, different season, and different reasons to go. Choosing between them is the first beach decision and most guides skip straight past it.
The Pacific
Longer, drier, more developed, and where most visitors go.
The north around Liberia at 86.9 nautical miles and Tamarindo at 97.1 gives reliable dry-season sun, blonde and grey sand, and the most infrastructure in the country.
The centre around Quepos at 33.4 nautical miles is greener, with rainforest coming down to the beach.
The south is the wildest and the hardest to reach.
What it does best: sunshine you can plan around, surf for every level, and beach towns with enough around them for a week.
The Caribbean
Shorter, wetter, greener, and culturally distinct — Afro-Caribbean, with its own food, music and rhythm. Many visitors say it is their favourite part of the country and most never go.
The sand around Puerto Viejo and Cahuita is whiter, the water is warmer and clearer, and there is reef.
What it does best: snorkelling, a genuinely different atmosphere, and lower prices.
Its season is inverted. September and October — the Pacific's worst months — are often the Caribbean's best. We fly year-round. In the rainy season the pilot in command decides; if weather stops a flight, it is rescheduled at no cost.
The swimming question, honestly
Many of the most photographed beaches are poor for swimming. Strong rips, steep shorebreak and no lifeguard.
The beaches that swim well are usually the ones in bays or behind reef: Manzanillo and parts of Cahuita on the Caribbean, Sámara and Manuel Antonio's park beaches on the Pacific.
Ask locally, every time. Conditions shift with tide and swell, and a beach that was calm yesterday may not be.
Quiet, if that is what you want
Nosara at 85.6 nautical miles, deliberately undeveloped.
Playa Grande, protected for turtles and quiet as a result.
The far south Pacific, around the Osa, where beaches are simply empty.
And most of the Caribbean outside the two main towns.
What the sand tells you
Colour here is geological rather than aesthetic. The dark sand on much of the Pacific is volcanic, which is also why it gets hot enough by midday to hurt bare feet — a detail visitors discover the hard way on the walk back from the water.
The paler Caribbean sand is coral-derived, which is the same reason there is reef to snorkel. The two facts are connected, and knowing that makes the choice between coasts easier than any list of beach names.
Choosing
Reliable sun in January: Pacific north. Snorkelling and a different culture: Caribbean. Wildlife on the beach: central Pacific. Empty: far south, or Caribbean off-season. Surf lessons: Pacific, almost anywhere.
Reaching them
The Pacific beaches are well served by strips, and what each accepts depends on runway and group size rather than preference. The specific aircraft is assigned on confirmation, based on passenger count, baggage and the destination field.
The Caribbean is the harder one, which is part of why it stays as it is, and the reason a Caribbean leg is worth planning rather than improvising. We show a "from" price per route; the final fare depends on the date, the group and the baggage, and is confirmed in writing before booking.
Frequently asked
Which coast should I choose?
Pacific for reliable sun, surf and infrastructure; Caribbean for snorkelling, a distinct culture and lower prices.
Do the two coasts share a season?
No. September and October are the Pacific's wettest months and often the Caribbean's best.
Are the famous beaches good for swimming?
Often not. Many have strong rips and no lifeguard. Bays and reef-protected beaches swim better.
Where do I go for quiet?
Nosara, Playa Grande, the far south Pacific, or the Caribbean outside the two main towns.
Which coast is easier to reach?
The Pacific, which is well served by airstrips. The Caribbean is harder, which is part of why it stays as it is.
How do I know if a beach is safe today?
Ask locally. Conditions change with tide and swell, and yesterday's calm beach may not be today's.
