Looking for the cheapest, easiest beach escape from Buenos Aires with a kid in tow? Florianópolis—“Floripa” to locals—hits the sweet spot. It’s a 2-hour flight away, offers calm family beaches in the north and wild dunes in the east, and has tons of inexpensive “por quilo” eateries and supermarkets for self-catering. Argentines love it for a reason: it’s friendly, safe by Brazilian big-city standards, and the water is warm enough in summer.

Floripa blends Azorean fishing villages with modern resort strips, so your days can swing from simple grilled fish in a bayfront village to sandboarding down the Joaquina dunes at sunset. The historic center has a market hall that’s a cheap-and-cheerful lunch stop, while Lagoa da Conceição is your hub for paddleboards, cafés, and a breezy evening stroll.

Practical notes: Portuguese is the language; Argentines don’t need a visa for Brazil. Peak season is December–February (highest prices); the best-value months are November and March–April. Rideshares (Uber/99) are inexpensive; buses connect the island, but families usually prefer rideshares for speed with beach gear. Bring cash for small kiosks; cards are widely accepted at restaurants.

Getting there from Buenos Aires: Direct flights (AEP/EZE → FLN) take ~2h. In shoulder season, round-trip fares often land in the US$140–300 range per adult if you book early (kids usually a bit less). Search and compare on Kiwi.com and Trip.com Flights. From FLN airport, an Uber to Canasvieiras is typically R$80–140 depending on time of day (30–60 minutes).

Day 1: Fly to Floripa, Beach Walk, Simple Seafood

Morning: Fly Buenos Aires to Florianópolis. Aim for a morning departure to arrive mid-afternoon. On arrival, grab an Uber to your stay in Canasvieiras or Lagoa da Conceição.

Afternoon: Unpack and take a first dip at the nearest beach (Canasvieiras for calm, shallow water that’s perfect for kids). Pick up essentials—water, fruit, snacks—at a local supermarket for budget-friendly breakfasts.

Evening: Casual, affordable dinner near the beach. Try “por quilo” buffets where you pay by weight (great for picky eaters). In Canasvieiras, look for spots advertising “prato feito” (daily plate) of grilled fish, rice, and beans. Finish with açaí bowls from a beach kiosk.

Day 2: North Island Trio—Canasvieiras, Jurerê, and the Old Fort

Morning: Breakfast pastries and good coffee at Café Cultura (multiple branches; Jurerê has one). Head to Jurerê for clear, gentle water and soft sand. Let your daughter collect shells and paddle in the shallows.

Afternoon: Walk or short ride to Fortaleza de São José da Ponta Grossa (near Praia do Forte/Jurerê). The 18th-century fort has grassy ramparts and ocean views—kids love exploring the cannons. Grab a budget lunch of pastéis (stuffed, fried pastries) or a fish plate at a simple beach shack nearby.

Evening: Ice cream stop at a local gelateria in Canasvieiras or Ingleses (Monte Pelmo in Ingleses is a beloved classic for big scoops at fair prices). Dinner: share a moqueca (Brazilian fish stew) at a neighborhood restaurant, with rice and farofa—big portions, great value.

Day 3: Barra da Lagoa, Projeto TAMAR, and Natural Pools

Morning: Bus or Uber to Barra da Lagoa. Visit Projeto TAMAR (sea-turtle conservation center)—a hit with kids; expect simple exhibits and close-up looks at rescued turtles. Then stroll the pedestrian bridge and follow the easy trail to the natural pools (Piscinas Naturais) for calm snorkeling on low-swell days.

Afternoon: Budget lunch: order a plate of grilled fish with salad and rice at a family-run spot like Bistrô do Mirante or a beachfront “prato feito” stand. Post-lunch, enjoy Lagoa da Conceição’s waterfront playgrounds or rent a paddleboat for 30–60 minutes.

Evening: Explore Lagoa da Conceição village. For a casual meal, try a “lanches” bar for burgers, hot pressed sandwiches, and fresh juices. Parents can sample a local craft beer while the kid digs into a pão de queijo.

Day 4: Campeche Island and Sandboarding at Joaquina

Morning: Head to Praia do Campeche. If the weather is settled, take a licensed boat to Ilha do Campeche (clear, turquoise water; lifeguards in high season; bring cash and snacks). Boats typically run morning–early afternoon; expect R$200–300 per adult in peak months; kids often discounted.

Afternoon: Stop at the Joaquina Dunes to rent sandboards (R$20–40 per board). There are gentle slopes perfect for kids. It’s sandy fun, cheap, and makes for great photos.

Evening: Dinner near Lagoa da Conceição. For something classic and fairly priced, try Ponta das Caranhas (moquecas, shrimp, fish plates to share). Grab brigadeiros or açaí for dessert on the boardwalk.

Day 5: Oyster Route—Ribeirão da Ilha and the South

Morning: Uber to Ribeirão da Ilha, an Azorean village of colorful houses, calm bay views, and oyster farms. Stroll the waterfront pier and watch small boats bring in baskets of oysters and mussels.

Afternoon: Lunch at Ostradamus if you want the island’s most iconic oyster experience (order a mix—au gratin and natural). For a lower bill, choose a simpler bayfront eatery offering fish-of-the-day with rice and salad. After lunch, continue to Pântano do Sul and walk the wide, uncrowded beach.

Evening: Eat at Arante in Pântano do Sul, famous for walls papered with handwritten notes left by diners; the house shrimp and fish stews are hearty and shareable. Head back to base for an early night.

Day 6: Downtown Floripa, Mercado Público, and Beira-Mar Sunset

Morning: Go into the historic center. Pop into the Metropolitan Cathedral and the fig tree at Praça XV. Browse the Mercado Público—it’s full of wallet-friendly counters; order a fried fish sandwich or pastel and fresh juice.

Afternoon: Free time at the beach closest to your stay. If you’re in Ingleses or Canasvieiras, consider a short hop to Praia Daniela for especially calm waters—great for kids and paddleboards.

Evening: Walk the Beira-Mar Norte promenade at sunset—families, cyclists, and street snacks. Dinner near your stay: look for a “self-service por quilo” buffet to keep costs low and plates kid-approved.

Day 7: One Last Swim, Souvenirs, and Fly Home

Morning: Final splash at your favorite beach. Pack a simple picnic from the supermarket for the airport. Grab a last coffee at Café Cultura or a neighborhood padaria.

Afternoon: Uber to the airport (plan 1–1.5 hours before boarding given island traffic). Fly FLN → Buenos Aires. If you prefer to compare fares or flight times last-minute, check Kiwi.com and Trip.com Flights.
