In my opinion, if you don’t plan on hiking or participating in activities like canyoning, dolphin and whale watching, etc., but simply want to explore the island, see all its beautiful views, and visit the main attractions, 4 days would be a more suitable timeframe for a quick tour of the island, allowing you not to miss its key highlights.
The second, third, and fourth days can be rearranged, but I recommend following the order I’ve created, as visiting these places in this sequence is, in my opinion, the best way to fully understand and experience the island. Of course, you should always consider weather conditions and check cloud cover in the areas you plan to visit using local webcams.
