Yes. You can no longer enter Costa Rica with just your birth certificate. Passports must be valid for six months AFTER your return. It’s also a good idea to make copies of your passport to carry with you, leaving the original in your villa. The Beach House conveniently has safes available for use in each villa for you to store valuable items such as important documents, laptops or cell phones. You may consider printing out and bringing any other travel documents you have, or useful travel info you think you might need and keep them in the safe provided.
