Agadir works best when beach time is protected instead of filling every day with excursions.
Day 1: beach and promenade
Start with the beachfront, marina and a relaxed sunset walk.
Day 2: city and Souk El Had
Use the second day for the local side of Agadir and its large market.
Day 3: Taghazout or nearby coast
Add a coastal excursion for surfing, cafés and a different seaside atmosphere.
Day 4: nature or slow resort time
Choose Paradise Valley or keep the final day deliberately slow around the beach and hotel.
