Visit the archaeological site of Joya de Cerén, a UNESCO World Heritage Site known as the Pompeii of America. This site is unique in the world as it is the only archeological site where you can see the actual former dwelling places of the Mayas.
Then visit the ruins of San Andrés, a political-ceremonial site where you can see the indigo pools in the area. Also see the ruins of Tazumal, a sophisticated Maya settlement. The ruins of Tazumal are considered the most important and best preserved in El Salvador. Virtually untouched since the year 1200 when it was abandoned, this archeological site provides an amazing look into the Maya ceremonial architecture

If you're in El Tunco and want to learn to surf, definitely take lessons with Wayo. I had always wanted to try surfing and decided to take a couple of lessons. Wayo is really patient and motivating, which was helpful as I was a bit nervous. Wayo also speaks English really well, which is super helpful. His explanations were clear and to the point, and he got me standing up on a board quickly. The other instructors are really great as well. They are always happy to give great advice and tips to improve your new skills. I definitely recommend learning to surf with Wayo or one of the instructors at his shop. It will be a highlight of your trip in El Salvador.
