Work out what you can see for free in Cape Verde before you rent a car, because several of the best views here don’t cost anything beyond getting there. Free viewpoints The Fontainhas village viewpoint on Santo Antão costs nothing: pastel stone houses perched on a narrow ridge above a deep green ravine, best seen from the clifftop trail rather than a vehicle. Monte Leão on Sal, a volcanic headland shaped like a sleeping lion, is another free coastal stop, paired with the Buracona rock pool nearby, known locally as the Blue Eye.

Book the room before you book the flight if a Cape Verde festival is anywhere near your dates, because the free events are the ones that fill hotels fastest. Free: Baía das Gatas and weekly morna The Festival de Música da Baía das Gatas, held on São Vicente every August during the full moon, is a free open-air beach concert running three days straight through Morna, Coladeira, Funaná, reggae, and Kizomba, and it draws tens of thousands of people who pay nothing at the gate.

Price the ferry before you price the hike: Santo Antão holds Cape Verde’s best trekking, and it has no airport, so every outdoor budget here starts with a boat ticket. Getting to the trails The only way onto Santo Antão is the CV Interilhas ferry from Mindelo (São Vicente), a scenic 60 minute crossing running 2 to 3 times daily for around 1,500 CVE (about €14) each way for non-residents, roughly 950 CVE for residents.

Work out what’s genuinely free before you book a single Cape Verde family activity, because the honest split here is sharper than most brochures let on. Free: salt water and shark watching Floating in the Pedra de Lume salt crater on Sal costs nothing beyond getting there: the extinct volcanic caldera holds water 27 times saltier than the open sea, so children float without effort. Shark Bay, also on Sal, is a shallow tidal pool near Parda Bay where juvenile lemon sharks, generally 1 to 2 meters long, swim around ankle height.

Budget for Cape Verde’s adventure sports by island, not by activity. The same 110.265 CVE peg to the euro holds across the archipelago, but what you spend, and what you need a guide for, changes completely once you leave Sal. Kitesurfing and windsurfing: Sal and Boa Vista Kite Beach (Costa da Fragata) on Sal’s east coast has steady 18 to 25 knot side-onshore trade winds and shallow sand, so it’s where the schools cluster and where beginners should book lessons.

Three days is not enough to island-hop Cape Verde on a budget, so this plan does not try. It stays on one island, Sal, and spends every euro on the free beach, a salt-pan float, and cheap local transport instead of a domestic flight or ferry that would eat half the trip and most of the daily budget. The escudo (CVE) is pegged at roughly 110 to the euro, euros spend fine on Sal, and the one real fixed cost before you even land is Cape Verde’s EASE pre-registration fee.

Cape Verde is ten volcanic islands scattered across open Atlantic water, not one landmass you can circuit in four days, so the budget move is picking two islands that are cheap and easy to link, not chasing all of them. This plan pairs Sao Vicente’s Mindelo with Santo Antao’s hiking trails via the one-hour Mindelo to Porto Novo ferry, the cheapest and most reliable inter-island connection in the country. Expect guesthouse rooms for EUR 15-25 a night, cachupa dinners for EUR 4-7, and aluguer minibus rides for a few hundred escudos.

Cape Verde is ten volcanic islands scattered across open Atlantic water, not one landmass you can circuit in a week, so a full seven days on a budget buys three islands and exactly one domestic flight, not five islands and constant transfers. This plan starts with the Mindelo and Santo Antao pairing this whole site’s shorter itineraries build around, then adds a third island, Santiago, using a single Cabo Verde Airlines flight through the Sal hub.
