The Musts: Costa Rica
I am OBSESSED with Costa Rica. I've only been twice: once to Santa Teresa to ring in the new year and once to Tamarindo for a yoga & adventure retreat with Ketanga Fitness (Check them out - Britney is an amazing yoga instructor and Stacy an amazing planner!). Although the activities are the same both places, they have a different vibe - Santa Teresa much more remote and Tamarindo more built up. I felt safer in Tamarindo and more adventurous and free in Santa Teresa. And I highly recommend them both.
*If you chose Santa Teresa, know that most places only take cash
Obviously go for fish when you're in Costa Rica. It's fresh AF. PS - not every restaurant looks the same in Costa Rica, just my favorites :)
Every day is an appropriate day for happy hour in Costa Rica. And if you're looking to go out later, the whole town goes to the one place each night. Ask a local every day and they'll let you know!
Bathing suits, workout clothes, shorts, and cotton dresses should do the trick! Definitely invest in a one piece wetsuit. Mine is from RipCurl.
ALWAYS WEAR FLATS! No one is wearing heels/wedges + it would be impossible to walk in them.
