The Top Things To Do in San José, Costa Rica, in 24 Hours

Kick off your San José adventure at the Plaza de la Cultura, the beating heart of the capital of Costa Rica. This lively square buzzes with energy as locals and visitors mingle beneath swaying coffee plants in this traffic-free, pedestrian-friendly square that’s right off bustling Avenida Central, the city’s main road. Government buildings frame the space, but the real treasure lies underground.

Head underground, below the square, to discover the Museo de Oro Precolombino (Pre-Columbian Gold Museum), which is home to one of the most impressive collections of ancient artifacts in Central America. Established in 1982, this museum showcases the incredible goldsmithing mastery of the Diquís culture and other indigenous peoples who called this land home long before Spanish conquistadors arrived. If you want to understand Costa Rica's deep roots, this is where your journey through history begins.

Right on the same Plaza de la Cultura stands one of the most spectacular things to do in San José: Checking out the inside of the National Theater. This 1897 architectural masterpiece stops you in your tracks with its neoclassical facade, but wait until you step inside. Marble floors gleam beneath gilded ceilings, while stunning murals and paintings take center stage. The theater’s most famous painting is Alegoría al café y el banano, which highlights Costa Rican agricultural life by capturing the coffee and banana harvests.

You can tour the theater's lavish interior, but the ultimate experience is catching a live performance. If you don't speak Spanish, opt for a concert where the music does the talking.

From the Plaza de la Cultura, follow the crowds onto Avenida Central, San José's main artery and the perfect place to experience authentic tico life. (Tico means “Costa Rican” in English.) This pedestrian street pulses with street performers, local vendors, cafés spilling onto sidewalks, and Costa Ricans going about their day. Hunt for unique souvenirs here, from handcrafted artwork to locally roasted coffee and rich Costa Rican chocolate. But mostly? Just soak in the atmosphere and watch the city unfold around you.

One of the best things to do in San José is visit the National Museum. Sitting right on Avenida Central, it houses an impressive collection of treasures spanning pre-Columbian cultures to the modern era. One of its standout features lies in the gardens, where you’ll find the perfectly round stone spheres of the Diquís people. Archaeologists have discovered these mysterious objects across Costa Rica, yet their purpose remains unclear. Their near-perfect geometry continues to spark debate and fascination to this day.

Inside, the museum tells Costa Rica’s full story, from ancient societies and Spanish conquest to the present day. With rotating exhibitions that keep the experience fresh, it’s an essential stop for understanding how the capital of Costa Rica came to be.

Ready for lunch? Skip the tourist traps and head to Mercado Central, where real Costa Ricans eat. Built in 1880, this sprawling market hall winds through tight corridors lined with over 200 vendors selling everything from tropical fruits to handmade crafts. The air fills with the scent of fresh spices, ripe mangoes, and brewing coffee.

But the real draw are the sodas, small family-run eateries serving authentic Costa Rican dishes at prices that'll make you smile. Grab a seat at a counter, order casado (the traditional plate of rice, beans, plantains, salad, and your choice of protein), and eat like a local. This market is where San José's soul comes alive.

Just a short walk from the National Theater is San José’s Barrio Amón. Stepping into this neighborhood feels like stepping into a different era. This gorgeous area showcases 19th-century architectural gems in Victorian, neoclassical, and Neo-Mudéjar styles that photographers dream about. But here's the twist: vibrant street art splashes across Barrio Amón’s walls and buildings, creating an electric contrast between old-world elegance and modern creativity. Barrio Amón blends 19th-century elegance with cutting-edge street art in a unique and creative way.

Today, this former elite neighborhood has transformed into San José's hippest district. Cozy cafés serve outstanding Costa Rican coffee, while restaurants dish up everything from traditional gallo pinto to international fusion. This is the perfect spot for a mid-afternoon break after all that sightseeing.

A post office building might sound mundane, but this Neo-Renaissance beauty designed by Catalan architect Luis Llach Llagostera ranks among San José's most photographed landmarks. Ornate columns and detailed decorations make the facade a work of art, while inside, the museum traces Costa Rica's communication history through stamps and postal artifacts.

Here's a surprise: The capital of Costa Rica houses the world's largest jade museum. Costa Rica's rich jade deposits attracted ancient artisans who transformed this semi-precious stone into exquisite jewelry and ceremonial objects. The museum displays around 2,500 jade pieces alongside nearly 7,000 additional artifacts from indigenous cultures. This one-of-a-kind collection makes it one of the most unique things to do in San José.

San José Cathedral might appear modest compared to Europe's grand cathedrals, but as Costa Rica's most important house of worship, it holds deep significance. Construction began in 1825, just a decade after San José gained city status, though earthquakes forced multiple facade reconstructions over the years. The result is an interesting architectural blend.

Another couple of churches not to be missed are the neoclassical Iglesia de Santa Teresita, built in the early 1900s, and the neo-Gothic Iglesia de la Merced, built in the late 1800s. Both churches showcase Costa Rica's colonial religious heritage.

Even in the heart of the city, Costa Rica's famous lush vegetation thrives in numerous parks that serve as gathering spots for locals. Parque Metropolitano La Sabana is the largest park in San José, and it’s also home to the national soccer stadium and sports facilities.

For a more intimate green-space experience, check out Parque Morazán, which hosts regular events near the its fascinating Edificio Metálico (Metal Building), an entire structure built from iron in the late 1800s. Or rest your feet at Parque Central, conveniently located near the cathedral.
