Do we really need rain gear in the dry season?

Yes. Costa Rica is a rainforest climate. A sudden 20-minute downpour can happen even in the 'dry' season, especially in the afternoons.

Should I bring a fancy outfit for dinner?

No. Costa Rican beach towns are very laid back. Nice shorts and a clean polo or a sundress are the most formal you will ever need.

Is it worth bringing snorkel gear?

Only if you have your own high-quality masks. Otherwise, rent locally to save luggage space and avoid the hassle of packing bulky gear.

Packing for a Family Beach Trip to Costa Rica

Pack lightweight, moisture-wicking clothing for the tropical humidity and prioritize sun protection and waterproof gear. Leave your heavy cotton fabrics and formal attire at home, as the coastal culture is strictly casual and heat-focused.

Select the right luggage. Use soft-sided duffel bags or backpacks rather than hard-shell suitcases. They are easier to stow in the back of small shared shuttles or 4x4s common in Costa Rican beach towns.
Organize with dry bags. Pack individual sets of clothes in dry bags or compression cubes. This protects your gear from sudden tropical downpours and sand at the beach, and keeps damp swimsuits separate from dry clothes.
Optimize for sun and bugs. Pack long-sleeved UPF shirts and pants for the kids to minimize sunscreen application time. Bring a high-DEET repellent for dusk and a DEET-free alternative for daytime use.
Prioritize footwear. Limit each person to one pair of supportive hiking sandals (like Tevas or Keens) that can handle water and trails, plus one pair of flip-flops for the hotel.
