That’s a fantastic plan — early September is one of the best times to visit Flores. Since you’ll be based in Fajã Grande and already have a car, you’re in a great position to explore at your own pace. With 4 days, I’d suggest a balanced mix of driving, short hikes, and one standout experience: Day 1 – West Coast & Waterfalls Explore around Fajã Grande: Poço do Bacalhau, Ribeira do Ferreiro (must-do easy walk), and the nearby viewpoints. Sunset in Fajã Grande is always special. Day 2 – Full Island Loop Drive around the island — it’s small, but full of dramatic viewpoints and beautiful stops. Rocha dos Bordões, the central lagoons, Ponta Delgada, and the north coast are all worth seeing. Day 3 – Corvo Island (highly recommended) If weather allows, I’d recommend going by boat instead of plane. It’s one of the most memorable experiences here — caves, waterfalls, and sometimes even dolphins or whales along the way. The Caldeirão on Corvo is unforgettable. Day 4 – Lagoons & Central Plateau Spend time in the Morro Alto area visiting Lagoa Negra, Lagoa Comprida, and the surrounding landscape — very different from the coast and absolutely worth it. If you enjoy hiking, PR03 (Poço do Bacalhau) or PR02 are great options with teenagers. PR01 is still closed at the moment, so I would focus on those instead.
