To make packing easier, it’s useful to visualize what you’ll be up to on your adventure vacation: waterfall rappelling, white water rafting, zip-lining, hiking, horseback riding, surfing.

What do all of these activities have in common? They are outdoors. So pack clothes that are comfortable and that you don’t mind getting wet and dirty, but remember at night you’ll usually have a chance to unwind and enjoy a nice dinner. Here’s a list to help you out:

-Quick-drying shirts and pants for hiking and other activities (most of Costa Rica is very humid). Bring at least one pair of longer pants for activities that require a harness and for horseback riding
-Casual wear for dinnertime
-A swimsuit or swimming trunks
-One or two sets of warmer clothes for areas like San José and Monteverde, where nights are chillier (60oF)
-A rain jacket or poncho
-Plenty of socks and underwear
-Sturdy, closed-toed shoes for hiking
-Sturdy water shoes for rafting and waterfall rappelling (some brands like Teva have styles that work well for both hiking and water activities)
-Flip flops for relaxing at the hotel or at the beach
-Hat, sunglasses, sarong, and any clothes wear that will help protect you from the sun. Remember Costa Rica is only 10 degrees north of the equator, and the sun can be dangerous!
-Reusable water bottle
-Sunblock, insect repellent and your personal toiletries
-Any medications you require (there are drugstores in Costa Rica, but it’s best to bring your own just to make sure you don’t run out of a particular medication you rely on)
-A flashlight
-Your camera, with a sturdy, waterproof case if possible
-Passport, driver’s license (plus copy of each) and credit card

Remember domestic airlines allow between 25 and 40 lbs maximum in your luggage, after which they’ll charge extra for each extra pound (about $1 per pound), so try to bring only the essentials!
