Costa Rica is a country that will humble your packing. You'll book a trip thinking "beach vacation" and discover you also want to hike through cloud forest, zip-line over canopy, explore a volcano, and kayak through mangroves. The terrain changes completely every few hours — and so does the weather.

Pack for the activities, not just the destination.

Understanding Costa Rica's Microclimates

Dry season (December–April): Sunny and warm. Guanacaste and the Pacific coast are at their best. The Caribbean side still sees rain.

Green season (May–November): Lush, less crowded, often cheaper. Afternoon rain showers are normal — usually 1–2 hours then it clears. Not a reason to avoid the country; the landscapes are greener and more dramatic.

Year-round: It's hot in the lowlands (30°C+), significantly cooler in the highlands. Monte Verde cloud forest can feel like a different country from Manuel Antonio beach.

Clothing

Base Wardrobe

Lightweight t-shirts × 4 (moisture-wicking synthetic or merino — not cotton)
Shorts × 2–3
1 pair of lightweight quick-dry hiking pants (converts to shorts if zip-off style)
1 light long-sleeve shirt (sun protection, bug protection, cool evenings)
Swimsuit × 2 (you'll swim in the Pacific, the Caribbean, and hot springs)
Underwear × 5–6 (moisture-wicking — chafing in humidity is real)
Light rain jacket or packable poncho (essential, not optional)

For Highland/Cloud Forest Regions (Monte Verde, Arenal)

Fleece or light insulating layer
Long pants
Waterproof shoes or trail runners

Footwear

Hiking shoes or trail runners (essential) — Costa Rica's trails are muddy, steep, and rocky. A good pair of trail runners handles 95% of activities better than dedicated hiking boots. Waterproofing is a bonus.

Sandals (essential) — for beaches, towns, and casual days. Chacos or Tevas with back strap, not flip flops.

Water shoes (optional but recommended) — for river crossings, snorkeling, and beach walks with rocks.

Skip: Casual sneakers that aren't waterproof. They'll be destroyed in two days.

Gear for Activities

Hiking

Quality rain jacket
Trekking poles (optional, but Arenal and Monteverde trails are steep)
Dry bag or waterproof bag liner
Headlamp (start hikes early; afternoons = rain)
Hat with full brim

Water Activities

Reef-safe sunscreen (non-negotiable — chemical sunscreen is banned in many protected areas)
Rash guard (long-sleeve for snorkeling and kayaking — sun on the water is intense)
Underwater camera or waterproof phone case
Quick-dry towel

Wildlife Watching

Binoculars (worth every gram for bird watching — Costa Rica has 900+ species)
Headlamp for night walks
Insect repellent

Health Essentials

Insect repellent with DEET (20–30%) — mosquitoes carry dengue fever and, in some areas, zika. Don't skip this.

Anti-malarial medication — not required for most tourist areas but recommended for remote Caribbean coastal regions. Consult your doctor before the trip.

Sunscreen SPF 50+ (reef-safe) — the equatorial sun is brutal. Reapply every 2 hours.

First aid kit:

Antiseptic wipes and cream (cuts from falls on trails happen)
Blister treatment
Ibuprofen + paracetamol
Antihistamine (allergic reactions to insect stings)
Antidiarrheal medication
Oral rehydration sachets

Vaccinations to check: Hepatitis A and B, typhoid, rabies (for adventure travelers), yellow fever (if entering from affected countries).

Water safety: Tap water is safe in most urban areas (San José, Tamarindo, Manuel Antonio). In rural areas, use filtered water or bottled.

Toiletries

Full-size toiletries are available in grocery stores in major towns. Pack travel sizes or plan to restock:

Reef-safe sunscreen (harder to find outside San José)
Insect repellent (easy to find, but better to arrive with it)
Anti-chafe stick or powder (humidity + walking = chafing)

Electronics

Waterproof phone case or dry bag — absolute requirement. Rain, waterfalls, river crossings, boat rides all threaten your phone.
Portable battery bank — long days away from outlets
Adapter — Costa Rica uses US-style Type A/B plugs (no adapter needed for North Americans)
Camera — GoPro or similar action camera is excellent value here
Offline maps — Maps.me has good offline Costa Rica data; download before you go

Bag Strategy

40–50L backpack works perfectly for 1–2 week Costa Rica trips. You move frequently (new regions every 2–3 days is normal) and won't have porters — a wheeled bag is a liability on shuttle buses and gravel roads.

Day pack (15–20L) — for hikes, day trips, and activities. Leave your main bag at the hotel.

Dry bag or liner — waterproof your pack. Rain is guaranteed.

Money & Logistics

US dollars — widely accepted alongside colones
Credit card (Visa/Mastercard widely accepted in tourist areas)
Some local colones for markets, rural vendors, public transport
Emergency cash separate from wallet

Driving in Costa Rica: If renting a car (highly recommended for flexibility), bring your driver's license. Many roads are unpaved — check that your rental includes off-road or dirt road coverage.

What to Leave Behind

Anything that can't get wet or dirty
Dress shoes
More than 1 pair of jeans (jeans in humidity are miserable)
Expensive jewelry

Costa Rica is extraordinary. The biodiversity, the landscapes, the Pura Vida culture — it all exceeds expectations. Pack for the adventure, not just the beach, and you'll be ready for everything the country throws at you.
