Travel Tips

Weather Windows
Atlantic fronts move fast - check same-day forecasts before crater lake hikes or whale watches. Morning tours cancel less often than afternoon ones.
Island Hopping Flights
SATA/Azores Airlines hop between islands; book early in summer. On São Miguel, buses cover main axes but calderas are easier by hire car.
Furnas & Whale Fees
Furnas hot springs and botanical parks charge entry. Whale-watching operators include marine park fees in tickets - choose licensed boats.
Rain Shell Always
Assume rain every day and you will be happy when it stays dry. Waterproof shoes matter on muddy crater rims and coastal lava.
