One of the most beautiful coastlines might be the Algarve in Portugal. With it’s golden beaches and dramatic caves you have some stunning views.
What makes the Algarve especially unique is its ability to feel both adventurous and peaceful. You can kayak through sea caves in Benagil in the morning and sip wine at a quiet cliffside restaurant by evening. And in between you can go surfing. There are several surf schools who will teach you how to catch some waves.
