What to do in Costa Rica in April
The weather in April in Costa Rica is still reliable enough for hiking, beach time, and outdoor adventures. If you’re planning on diving or snorkeling, visibility on the Pacific coast is usually at its clearest now. You’ll also catch a few local celebrations this month that give you a better sense of everyday life here.
Bird watching in the Central Valley
Birding in the Central Valley is especially active in April. Local birds are in breeding season, which means they’re more visible and vocal, and some migratory birds are still around before heading back north. Mornings are usually cooler and clearer, so it’s a good time to head out early.
Even if you’re not a hardcore birder, it’s easy to spot colorful species like toucans, tanagers, and hummingbirds just by walking through yards or coffee plantations. If you’re hoping to see a quetzal, this is a good month for it—they’re feeding on wild avocados and tend to show up more often.
Día de Juan Santamaría
On April 11, towns across Costa Rica mark Día de Juan Santamaría, a national vacation honoring the country’s most well-known folk hero. Alajuela, where he was born, is the main hub for celebrations, but you’ll find parades, music, and dancing in other parts of the country too. Streets usually fill with traditional dress and live performances, and you’ll see plenty of local food stalls—chorreadas and chicharrones are common favorites. The day also holds a lot of historical meaning. It commemorates the 1856 battle where Santamaría played a key role in defeating invading forces, which shaped Costa Rica’s national identity and helped cement its military-free status. It’s a day locals take seriously, but it’s also welcoming and easy to experience as a visitor. This is a great thing to do in Costa Rica with kids.
Visit the bioluminescent bay (Punta Mona)
If you’re heading to the Caribbean side, April’s a good time to visit Punta Mona to see bioluminescence. It happens all year, but April tends to have warmer nights and calm water, which makes it easier to spot. Go during a new moon when it’s really dark out—you’ll see glowing blue light in the water caused by tiny microorganisms that light up when moved.
Night kayaking is a good way to experience it, but you can also swim if conditions are calm. Every splash or paddle stroke sets off a shimmer beneath the surface. Punta Mona is pretty remote, so you’re away from city lights, and if the skies are clear, you’ll get a great view of the stars above too.
