Santo Antão, reached only by ferry from São Vicente and famous for its dramatic volcanic peaks and terraced valleys, offers Cape Verde’s most rewarding hiking but among its most limited connectivity, particularly once you leave the main towns.
Quick answer: Coverage in Porto Novo and Ribeira Grande, Santo Antão’s main towns, is generally workable. Once you’re hiking the island’s famous trails through its dramatic valleys, expect coverage to disappear for extended stretches.
Top Cape Verde eSIMs
Coverage in Porto Novo
The town where ferries from São Vicente arrive maintains basic but workable coverage, sufficient for confirming plans before heading further into the island.
Coverage in Ribeira Grande
Santo Antão’s other main town, gateway to some of the island’s most famous hiking trails, maintains similarly basic coverage to Porto Novo — the São Vicente guide covers the departure island for this ferry route.
Coverage while hiking the valleys
Once on the trails through Paúl Valley or toward Cova crater, expect coverage to disappear for extended stretches — treat any extended hike here as genuinely offline, similar to considerations covered in the Fogo Island guide for another dramatic outdoor destination in Cape Verde.
Getting to Santo Antão by ferry
The crossing from São Vicente maintains variable coverage depending on your position — the ferry guide covers this specific crossing, and the internet in Mindelo guide covers connectivity in the departure city.
Preparing for a disconnected hiking trip
Downloading offline maps and informing someone of your planned route matters more here than any connectivity workaround, given how quickly signal disappears once you’re on the trails — the Cape Verde eSIM coverage guide covers this island-by-island coverage pattern.
