Playa Avellanas or Playa Conchal in Guanacaste
Published 2026-08-23. Conditions described are typical and never guaranteed.
Here is the short answer before you commit a morning to the wrong shore. If you surf, or you want to surf, or you simply love a long wild beach with a legendary lunch at the end of it, go to Playa Avellanas. If you want the calmest, clearest water on this coast and a soft floor to float over, go to Playa Conchal. These two beaches sit within a short drive of each other in the same stretch of Guanacaste, yet they ask completely different things of you, and they reward completely different visitors. One is built for waves and space. The other is built for stillness and shine.
That is the whole verdict in a sentence: Avellanas for the surfer and the walker, Conchal for the swimmer and the snorkeller. Everything below is about the details that flip that answer, because there are days and moods when the beach that sounds wrong for you turns out to be exactly right.
The sand tells the first story
Conchal is not sand in the ordinary sense. It is a pale floor of tiny crushed shells laid down over centuries, and that shell bed is the reason the water reads so clear and gives the bay its glow. It is soft and cool underfoot, though the coarser patches are firm enough that water shoes earn their place. It is genuinely unusual, one of those beaches that looks almost unreal in the early light. The crescent shape matters too, because it shelters the water and keeps the whole scene compact and easy to take in.
Avellanas is the opposite kind of beauty. It is a wide, mostly undeveloped sweep of golden sand backed by mangrove and palms, and it runs long enough that you can walk away from everyone. At low tide it opens up rock and reef sections and broad flat sand, which is wonderful for walking and rock pooling but a clear signal about the personality of the place. This is a natural surf beach, not a manicured one. If you love the feeling of a shore that has been left largely alone, Avellanas will speak to you in a way the neater beaches never quite manage.
Which sand suits you
- Choose Conchal if you want soft shell underfoot, a small compact bay and water that photographs like glass.
- Choose Avellanas if you want distance, wildness and the freedom to walk a long way from the crowd.
The water is where they truly split
This is the deciding factor for most readers, so be honest with yourself about it. Avellanas has consistent waves for all levels through the whole year, and it has currents. It is better for surfing than for casual swimming, and there is no dependable lifeguard watch, so you surf and swim within your ability and keep to your depth. That is not a warning to scare you off. It is the entire appeal for a surfer, because the beach picks up swell all year with beach, reef and river mouth sections at different tides, which is why some people call it Little Hawaii. For a family hoping for a gentle paddle, though, it is the wrong choice, and the beach itself will tell you so.
Conchal is the calm one. Sheltered inside its crescent and protected by an offshore reef, it offers some of the calmest and clearest swimming on the whole Pacific coast, and the rocky ends are the best spots for snorkelling. Conditions are calmest early in the day, before the afternoon wind arrives, so the golden window here is the morning. There is no reliable lifeguard here either, and the usual rule applies: swim within your depth even when the water looks tame. But as a place to actually get in and float, Conchal wins this category outright.
The simplest test: if the words waves and currents excite you, go to Avellanas. If they worry you, go to Conchal.
Facilities and how the day feels
Neither beach is a resort strip, and that is part of the charm, but they handle the practical day very differently. Avellanas centres almost everything on one address. The famous open air restaurant known as Lola's anchors the beach with wooden tables and big shaded loungers under the palms facing the surf, and it is the main source of shade, food and toilets on the sand. It is known for fresh fish, poke and smoothies. Two things to plan around: it traditionally closes on Mondays, so save your long lunch for another day, and weekends are its busiest time. Once you walk away from it, there is little else, so bring what you need if you want to roam the far sand.
Conchal keeps things even more stripped back. There are no public toilets or showers on the sand, although vendors rent chairs and umbrellas and sell cold drinks and ceviche in season. There is a resort behind the dunes with an optional day pass, but that is never required to enjoy the public beach. Because there is no road directly onto Conchal, you park in the village of Brasilito and walk south along the sand for five to ten minutes to reach the shells, and that short walk is exactly what keeps it quieter than beaches you can drive straight onto. Bring water, sun cover and snacks, since shade is thin and there are no shops on the beach itself.
Getting there, and the state of the road
Access is a real part of this comparison. Avellanas sits about a twenty minute drive south of Tamarindo on a rough, mostly unpaved road that needs care in an ordinary car, especially in the rains. Allow extra time and drive gently. Conchal is reached on foot from Brasilito, with some boat tours from Flamingo and Tamarindo dropping visitors directly on the beach as well. One more thing at Conchal: do not drive onto the shell beach, and please leave the shells where they are, as taking them home is discouraged and harms the bay.
Crowds, timing and the season
Both beaches share the same best months, December to April, when the dry season brings the surest sun and, at Conchal, the clearest water. Beyond that they diverge. Conchal is at its finest in the early hours before the wind, so an early start is the single best decision you can make there. Avellanas is quietest on a non Monday weekday, when Lola's is open but the weekend crowd has gone. If you are trying to line up tides, seasons and the calmest windows across the region, the seasonal timing notes for Guanacaste are worth a read before you fix a date.
When the other beach wins
The head to head is not absolute, and here is where the answer flips. A surfer who has promised the family a gentle swimming day should point the car at Conchal without hesitation, because it delivers the calm water that Avellanas simply does not. Families weighing up the coast in general will find more of this gentle mood gathered in the family friendly roundup.
Equally, a confident swimmer or keen surfer who spends a morning at Conchal and finds it too still, too small or too busy with day trippers should embrace the road to Avellanas for space, swell and that long empty walk at low tide. And if what you really want is the wild, protected version of a surf beach, note that nearby Playa Grande runs for kilometres inside a national park with turtle nesting seasons, while calmer town beaches such as Playa Flamingo and the tidy cove at Playa Danta below Las Catalinas offer gentler swimming with restaurants close behind the sand. Couples chasing quiet light and long lunches can compare the moods across the romantic shortlist, and anyone hunting emptier sand should scan the secluded beaches guide.
So, which one
Pick Avellanas if you surf, if you crave wild space, or if a long lunch at a beach institution is your idea of a perfect day, and simply plan around the Monday closure and the rough road. Pick Conchal if you want to actually swim and snorkel in the calmest, clearest water around, arrive early, and accept that you carry your own comforts down the sand. For the full picture of every shore in the region, the Guanacaste beach hub lays them side by side.
Turn a beach day into a club day
If you would rather add loungers, service and a base for the day to either of these shores, browse the options and enquire through the Guanacaste beach clubs page. Tell them the kind of water and pace you want, and match the club to the beach that suits you rather than the other way round.
