To simplify the task, we’ve selected some of the most popular destinations that should be on your itinerary for a December trip to this vibrant country. Let’s take a look!

National Parks

Costa Rica experiences a preferred climate that is perfect for making lush vegetation thrive and providing every visitor with outstanding landscapes. That’s why visiting at least one of the many national parks in Costa Rica is a must for nature lovers.

Manuel Antonio National Park

Manuel Antonio National Park, a crown jewel among Costa Rican tourist destinations, teems with wildlife, including monkeys, sloths, iguanas, snakes, and an astonishing diversity of over 1,000 bird species.

When you visit the park, you can choose between wandering through its hiking trails or visiting the region’s top-rated beaches like Escondido, Manuel Antonio, and Playa Espadilla Sur.

In this verdant ecosystem, you can also find numerous marine species, including moray eels, angelfish, and starfish.

Arenal Volcano National Park

Arenal Volcano National Park is a favorite among local and international tourists, boasting many outdoor activities amidst stunning landscapes.

Its most iconic feature, the Arenal Volcano, presents a perfectly symmetrical silhouette. Other park attractions extend beyond the volcano in the La Fortuna district. There’s the expansive Lake Arenal, the refreshing La Fortuna Waterfall and Rio Celeste, and the renowned Tabacón Hot Springs.

Corcovado National Park

Corcovado National Park, situated on the remote Osa Peninsula in Costa Rica, is a biodiversity hotspot. The park protects rainforests, mangroves, beaches, and marine habitats. As a result of this diversity, wildlife enthusiasts can observe exotic creatures in their natural habitats.

Trails extend across the park’s vast natural surroundings, making it a hiking paradise. There’s nothing like a hike through the park with the Pacific Ocean as a stunning backdrop.

Tamarindo Beach

Tamarindo Beach is a popular destination in Guanacaste Province with its golden sand and clear waters. This beach resort offers everything from surfing and snorkeling to horseback riding and zip-lining. 

After the sun sets, Tamarindo comes alive with an energetic nightlife scene. Watch the sunset over the Pacific Ocean while listening to live music and enjoying delicious drinks.

Playa Grande

North of Tamarindo lies Playa Grande, part of Marino Las Baulas National Park and a nesting site for endangered leatherback turtles.

In addition to its serene atmosphere, this beach is renowned for its excellent surf breaks, which are suitable for all levels of surfers. A vast expanse of sandy beach and verdant coastal vegetation provide a peaceful setting for strolls and sunbathing away from the usual tourist crowds.

Playa Matapalo

Playa Matapalo, located in Puntarenas, is an idyllic spot for those seeking tranquility. The uncrowded sands extend into the clear Pacific waters, making it an excellent location for sunbathing, swimming, and shell-collecting.

How crowded are tourist attractions in Costa Rica during December?

December in Costa Rica marks the peak travel season. Local and foreign tourists flock to popular destinations throughout the country.

In early December, San Jose, the capital, draws crowds with its parade of floats and light displays during the grand ‘Festival de la Luz.’ If you’re seeking accommodations in town during this period, you might find them more crowded and expensive than in the rainy season.

Other regions in Costa Rica also experience higher prices and more crowds during the country’s dry season. However, the vibrant atmosphere and splendid weather make visiting during the peak season highly rewarding.

Every December, the vibrant city of San José, Costa Rica, becomes a spectacle of colors and lights during the annual Festival de la Luz!

  • Swimwear: If you’re visiting the Pacific or Caribbean sides of the country, ensure you pack appropriate swimwear.
  • Appropriate footwear: Waterproof hiking shoes can make rainforest explorations and hikes comfortable. Consider water shoes for rocky beaches, river crossings, and wandering through the Costa Rican jungle. Casual sandals for beachfront strolls are also worth bringing.
  • Sun protection: With its equatorial sun, protection is a must. Pack sunglasses, a hat, and high-SPF sunscreen.

What to pack by activity

Do not repeat your master checklist here these are the additions that matter for specific trip types. Grab what applies to your itinerary and leave the rest.

Beach and water sports

  • Rash guard sun protection in the water is more effective than sunscreen alone
  • Waterproof phone case or action cam housing
  • Reef-safe sunscreen mandatory in marine reserves; this is not a suggestion
  • Water shoes for rocky beaches and shallow reef walks

Hiking and national parks

  • Trekking poles especially useful on steep, wet trails in Corcovado or Chirripó
  • Gaiters for deep mud on rainy season trails
  • Extra headlamp batteries early morning wildlife walks start before dawn
  • Microfiber towel compact and dries fast between hikes

Wildlife watching

What NOT to pack for Costa Rica

This is the section most travelers wish they had read first. Overpacking is the number one complaint we hear from guests on their first day. Less really is more when you are moving between regions.

Jeans: They never fully dry in the humidity. Swap them for quick-dry pants or shorts and thank yourself on day two.

High heels or dress shoes: You will not need them. Even nice restaurants in Costa Rica are casual. One pair of clean trail sandals does the job.

Too many shoes: Three pairs maximum: waterproof sandals, trail shoes, and flip flops. Shoes are heavy and take space.

Non-reef-safe sunscreen: It is prohibited in several reserves and harmful to marine ecosystems. Bring reef-safe from home. Brands like Raw Elements and Badger are good options.

A hair dryer: Almost every hotel and lodge provides one. Leave yours at home.

Valuables you cannot afford to lose: Leave the expensive jewelry and the laptop you need for work. Use your trip as a proper break.

Cotton everything:Cotton absorbs moisture and stays wet all day. Pack synthetics or merino for everything except maybe one casual outfit.

Practical tips for packing smart: documents, money, and tech

Your passport must be valid for the full duration of your trip.

Customs also requires a tiquete de salida proof of onward travel out of Costa Rica. This can be a return flight or a bus ticket to a neighboring country. Have it printed or easily accessible on your phone. See Costa Rica national park regulations via SINAC for entry requirements at protected areas.

Money

  • Colones (CRC) are the local currency; USD is widely accepted but change is given in colones
  • ATMs are available in most towns withdraw colones there rather than exchanging at the airport, where rates are poor
  • Visa and Mastercard accepted at most hotels, restaurants, and tour operators; carry some cash for small sodas and local markets

Health prep

Check the CDC health recommendations for Costa Rica before your trip they cover vaccines, repellent, and food safety guidance. Travel insurance is not required by law, but we strongly recommend it for anyone doing adventure activities.

Tech

  • Costa Rica runs on 110V/60Hz US travelers need no adapter or converter
  • Cell coverage is solid in tourist areas; download offline maps before heading into remote zones
  • WhatsApp is the primary communication tool in Costa Rica make sure it is installed and working

Do I need a visa to visit Costa Rica?

US, Canadian, and UK citizens do not need a visa to enter Costa Rica for stays up to 90 days. Your passport must be valid for the full duration of your trip. You will need to show a return or onward ticket at customs.

Is tap water safe to drink in Costa Rica?

Yes in most areas. Tap water in San José, Guanacaste, La Fortuna, and other major tourist regions is safe to drink and often tastes good. In very remote or rural communities, confirm locally before drinking. Carry a reusable bottle and refill with confidence in most places.

What is the best luggage for a Costa Rica trip?

A soft-sided rolling suitcase works well if you are staying in one or two places. If you are moving between regions beach, rainforest, and volcano a mid-size backpack (40–50L) is far more practical. It fits in small boats, shuttles, and keeps your hands free on trails. We see guests arrive with giant hard-shell suitcases and spend the trip wishing they had packed a bag.

Do I need to bring bug spray to Costa Rica?

Yes. We recommend a picaridin-based repellent like Sawyer 20% over DEET it works just as well in tropical conditions, does not damage gear or plastics, and has no harsh smell. Apply it especially at dawn and dusk during the rainy season.
