Réunion in 5 Days: The Perfect Extended Itinerary

A 5-day Réunion itinerary offers the perfect balance between the island's dramatic volcanic peaks, lush tropical cirques, and relaxing turquoise lagoons. By basing yourself in Saint-Denis and Saint-Gilles, you can explore the Piton de la Fournaise, the charming village of Hell-Bourg, and the winding roads of Cilaos while staying connected with a Hello eSIM for Réunion and tracking your expenses effortlessly in the Hello app.

Navigating Réunion requires a rental car, as public transport (Car Jaune) is reliable between coastal towns but less frequent for mountain reaches. In 2026, expect car rental prices to range from €45 to €75 per day depending on the vehicle class. Driving here is an adventure in itself, featuring the famous '400 bends' road to Cilaos. To navigate these winding mountain passes without getting lost, a reliable data connection is non-negotiable. You can purchase a Hello eSIM for Réunion before you land, ensuring instant access to GPS and local maps the moment you exit Roland Garros Airport.

Beyond navigation, managing a multi-day trip involves tracking various costs from fuel to mountain lodge stays. The Hello app is an essential travel companion for this, allowing you to scan receipts in Euros and automatically convert them to your home currency using real-time exchange rates. If you are traveling with friends, the app's expense-splitting feature ensures everyone pays their fair share of the rental car and petrol costs without the need for complex spreadsheets. According to the Île de la Réunion Tourisme (IRT), the island saw over 550,000 visitors in 2023, many of whom cited the island's rugged interior as the primary draw, making digital tools for navigation and budgeting more important than ever.

Start your Réunion 5 day trip in the capital, Saint-Denis. Spend your first morning walking along Le Barachois, the historic seafront, and exploring the Rue de Paris to see colonial architecture. For lunch, try a traditional 'Carri' (curry) at a local spot like Chez Callixte, where a meal in 2026 costs around €15-20. In the afternoon, drive east toward the Cirque de Salazie. This area is known for its 'weeping' mountains and the stunning Voile de la Mariée waterfall.

On day two, immerse yourself in Hell-Bourg, officially labeled one of the 'Most Beautiful Villages in France.' The village is a kaleidoscope of colorful Creole houses and lush gardens. Visit the Maison Folio to understand the island's botanical history (entry is approximately €6-8). Because mountain weather can change rapidly, use your Hello eSIM to check live weather radars before heading out on hikes. After a day of exploring waterfalls, use the Hello app’s voice expense entry to quickly log your museum fees and lunch costs, keeping your daily budget on track without missing a moment of the scenery.

The centerpiece of any Réunion travel plan is the Piton de la Fournaise, one of the world's most active volcanoes. To beat the clouds that typically roll in by midday, you should aim to arrive at Pas de Bellecombe by 7:30 AM. The hike to the Formica Leo crater is relatively short, while the full trek to the summit crater (Cratère Dolomieu) takes about 5-6 hours round trip. The landscape is otherworldly, resembling a Martian desert of red and black lava rock.

There is no entrance fee for the national park, but you should budget for a hearty mountain meal afterward. A traditional lunch in the nearby village of Bourg-Murat will cost about €25 per person in 2026. Since the volcano is a remote area, having an eSIM from Hello ensures you can still access emergency services or download offline maps if the signal dips in the deeper craters. According to the Piton de la Fournaise Volcano Observatory, the volcano erupts on average every nine months, so checking local updates via your data plan is essential for safety. Log these unique experiences in your Hello app to see how your 'Adventure' category is stacking up against your initial trip budget.

On day four, tackle the legendary road to the Cirque de Cilaos. This high-altitude caldera is famous for its lentils, wine, and thermal springs. Spend the morning hiking the Bras Rouge trail or visiting the local embroidery school. For dinner, enjoy a dish of Cilaos lentils and smoked sausage (Rougail Saucisse), a local staple. In 2026, a mid-range dinner in Cilaos typically costs €30 per person including local wine.

Conclude your Réunion itinerary on day five by descending to the west coast for some well-deserved relaxation in Saint-Gilles-les-Bains. The lagoon at L’Ermitage is protected by a coral reef, making it safe for snorkeling among tropical fish. Rent a paddleboard for about €20 per hour or simply enjoy a sunset cocktail at a 'rondavelle' (beach bar). As you wrap up your trip, the Hello app’s AI-powered categorization will give you a clear breakdown of your spending across the five days. You can easily export these expenses to a CSV if you need to settle up with travel partners, ensuring your tropical getaway ends with financial clarity rather than a mountain of receipts.

Planning a Réunion 5 day itinerary requires understanding the different price points available on the island. While the island uses the Euro, prices for services and dining can vary significantly between the coastal resorts and the mountain gîtes. Below is a breakdown of expected daily costs per person for different travel styles.

Using the Hello app to track these categories in real-time helps you stay within your chosen tier, especially when unexpected costs like park fees or specialized gear rentals arise.

When is the best time to visit Réunion? The best time for a Réunion itinerary is during the dry season, from May to October, when hiking conditions are optimal and temperatures are mild (20-25°C). The cyclone season runs from December to March, which can disrupt travel plans and trail access.

Do I need a 4x4 for a Réunion 5 day trip? While the roads are well-paved, they are incredibly steep and winding. A standard economy car is sufficient for most routes, including Cilaos, but an automatic transmission is highly recommended for those not used to frequent gear shifting on mountain inclines.

How do I stay connected in the mountains? Connectivity can be spotty in the deep canyons of the Cirques. However, an eSIM from Hello provides the best available coverage by hopping between local networks. It is always wise to download your maps for offline use via the Hello app before heading into the Piton de la Fournaise area.
