One carry-on. That's the goal. Costa Rica is warm, casual and forgiving about fashion — you do not need a checked bag. Here's what actually goes into a well-packed Costa Rica kit.
The layering principle
Costa Rica has five climate zones within a two-hour drive of each other. The coast is hot and humid; Monteverde is cool and misty; Arenal can be both. The solution is layers, not volume. Three thin breathable layers beat six thick items every time.
The core kit
Clothing:
- 3 quick-dry t-shirts
- 1 long-sleeve light shirt (sun + mosquitoes)
- 1 fleece or thin jacket (cloud forest evenings)
- 2 pairs of hiking trousers or convertible pants
- 1 swimsuit
- 7 pairs merino wool socks (dries overnight, no smell)
- 1 pair of packable sandals
- 1 pair of light hiking shoes (NOT heavy boots)
Gear:
- Reusable water bottle (1L minimum)
- Small dry bag (30L for your pack on boat days)
- Headlamp
- Insect repellent (DEET 30%+)
- Reef-safe sunscreen
- Small first aid kit
- Microfibre towel
Every year someone brings heavy hiking boots and regrets it. For 95% of Costa Rica trails, light trail runners or even clean sneakers are fine. Save the weight.
What to leave at home
- Hair dryer (every lodge has one)
- Umbrella (use a lightweight rain jacket instead — umbrellas don't work on forest trails)
- Jeans (too heavy to dry, too hot to wear)
- More than 2 pairs of shoes
- A 15kg camera bag (your phone is better in the jungle — protected, lightweight, always with you)
The hidden essential
A small dry bag or ziplock bags. Costa Rica is wet — whether it's rain, boat spray or a humid pack, your phone, passport and electronics will find moisture. Dry bags are not glamorous but they save expensive things. We see at least two drowned phones per tour season.
With a carry-on, you can move faster, hop on small planes to Osa or Tortuguero, and spend zero time at baggage claim. Pack less, see more. Check our packages if you want a list of what to bring for a specific trip — we send personalized packing lists to every confirmed traveler.
