RéunionLa Réunion
First trip: 7–10 nights split between the west coast (Saint-Gilles) and one or two inland bases (Cilaos or Salazie, and the Plaine des Cafres for the volcano), with a hire car; hike early, because clouds close the peaks by midday.
Réunion is an overseas department and region of France and part of the EU, with the euro, but it is outside the Schengen area and has its own entry rules for some passports. The island is small but mountainous: the cirques and the volcano are reached by winding roads or on foot, and weather in the mountains changes fast. Plan early starts for hikes, a car for the island, and flexibility for cyclone season (roughly December–March).

- Access to Piton de la Fournaise closes during eruptions and alerts; check the prefecture's current status before you go.
Etiquette
- French is the official language; Réunion Creole is widely spoken.
- Réunion is multi-faith (Catholic, Hindu, Muslim, Chinese traditions); cover up and remove shoes at temples when asked.
- Greet with bonjour when entering shops and small restaurants.
- Cyclone season (roughly Dec–Mar)
- Alerts can close roads, trails and flights for days.
- Dec 20 (Fèt Kaf)

Safety
- Shark risk: do not swim or surf outside the lagoon and supervised zones; bans are enforced.

- Emergency: 112 (EU-wide), 15 medical, 17 police, 18 fire.
Réunion connects by short flights with Mauritius, Madagascar, Mayotte and Seychelles; Mauritius is the easiest pairing.
