Local tips for Isalo & the RN7 south
Plan the transfer, not only the distance
Treat the suggested stay as time on the ground: weather, timed entry, ferries or mountain roads can remove half a day.
Pay on arrival or apply online
Fees are set by stay length and have changed several times; carry the exact amount in euros or dollars, a return ticket and a passport valid for six months.
Ariary is cash-heavy
ATMs in cities dispense small notes, cards work only in larger hotels, and euros exchange easily. Carry cash in the south, the west and on Sainte-Marie.
Telma or Orange SIM at Ivato
Coverage follows the main roads and towns; parks and the west have little. Download offline maps and share the driver's number with the lodges.
Type C and E sockets
220 V with two-pin European plugs; power cuts are routine, so a power bank and a head torch are standard kit.
