In just 2,500 km², Reunion Island packs in what other countries spread across whole continents: an active volcano, a lagoon, remote cirques, beaches, primary forest and even underground tunnels carved by lava.

Here are the 12 most unusual activities the island has to offer, grouped by theme (sea, air, volcano, adventure, nature). For each one: the starting price, the minimum age, what makes it unusual, and a link to a more detailed page where there is one.

The details

The 12 activities in detail

Watching and swimming with dolphins and whales in Reunion Island from Saint-Gilles
01SeaExperience #1
From €90

Swim with dolphins and whales

Saint-Gilles, west · All ages

“The island's most unforgettable encounter.”

A boat trip from Saint-Gilles harbour, up to 12 km offshore. When a pod is spotted, you slip into the water with fins, mask and snorkel. Dolphins year-round (Indo-Pacific bottlenose and spinner dolphins), humpback whales from June to October. A strict code of conduct applies: no chasing the animals, a minimum distance, and respect at all times.

Why it's unusual

A genuine wild encounter, not a marine park: the animals decide whether or not to come and see you.

02Adventure
From €110

Quad biking in the highlands of Saint-Paul

Maïdo, west · Driving licence required, passengers from age 6

Why it's unusual

A quad gets you to viewpoints over Mafate you could never reach on foot in half a day, through primary forest normally closed to the public.

03Adventure
From €55

Water hike in Langevin

Rivière Langevin, south · From age 6

A guided trip down the Rivière Langevin with qualified instructors: wading, swimming in pools, ziplines strung above the river, natural slides and small jumps (which you can skip). Wetsuit, helmet and water shoes provided. A 3-hour outing, suitable for families with children from age 6.

Why it's unusual

The only place on the island that mixes thrills (zipline, jumps) with gentle stretches on the same route. A perfect first taste of canyoning without the technical side.

Exploring a lava tunnel at Piton de la Fournaise with helmet and head torch
04Volcano
From €50

Exploring a lava tunnel

Sainte-Rose and Saint-Philippe · From age 7

“Walking through tunnels carved by lava.”

A 3-hour guided trip through the lava tunnels left by Piton de la Fournaise's eruptions, mainly the 2004 flow between Sainte-Rose and Saint-Philippe. Helmet, head torch and gloves provided. Remarkable geology: lava stalactites and stalagmites, ropy basalt, chambers several metres wide. Easy caving, open from age 7.

Why it's unusual

A unique perspective: you are literally walking inside the mould of a lava flow, under rock that cooled only a few years ago. A humbling sense of scale.

Ermitage lagoon, Saint-Gilles · All ages

“See the lagoon as if you were flying over it.”

A guided 90-minute trip in a two-seater glass-bottom kayak on the Ermitage lagoon. Look out for butterflyfish, damselfish, stingrays and sometimes green turtles as you paddle round living coral heads. Safety briefing and life jacket provided. Suitable for families with young children.

Why it's unusual

The lagoon is so clear you feel as if you are flying 50 cm above the coral. Unlike snorkelling, you don't need to be able to swim.

Tandem paragliding in Saint-Leu over the lagoon, Reunion Island
07Air
From €110

Tandem paragliding in Saint-Leu

Saint-Leu, west · From age 4, 100 kg max

“Flying over the lagoon, above the whales in season.”

A tandem paragliding flight with a qualified instructor, taking off from the hills above Saint-Leu and landing by the lagoon. Choose 20 or 40 minutes depending on weather and budget. From June to October you may spot humpback whales from the air (one of the few places in the world where that is possible).

Why it's unusual

Saint-Leu ranks among the world's three best paragliding sites for the reliability of its thermals, and very few places let you spot whales from the air.

Frequently asked questions

Unusual things to do: your questions answered

What is the most unusual thing to do in Reunion Island?
If you pick just one, make it swimming with dolphins and whales off Saint-Gilles. No other French department offers this, and few destinations anywhere apply such a strict code of conduct (respect for the animals' behaviour, minimum distance). June to October for humpback whales, year-round for dolphins.
Which unusual activities suit families in Reunion Island?
Three work particularly well with children: the Langevin river hike (from age 6, with thrills pitched at the right level), glass-bottom kayaking on the lagoon (all ages) and the lava tunnel (from age 7, a big hit with curious kids). Best avoided with younger children: bungee jumping and Fleur Jaune canyoning.
How much do unusual activities cost in Reunion Island?
Guide prices for 2026: from €50 (glass-bottom kayak, lava tunnel), €90 (swimming with whales, diving, bungee jump), €110 (quad, paragliding), €205 (volcano helicopter flight) and €305-345 (full helicopter tour). Allow €80-100 per adult on average for most guided activities.
How far ahead should I book?
High season (July-August, the French school holidays): 2 to 4 weeks ahead. Whale season (June-October): 2 weeks ahead for the swim. During a volcanic eruption, volcano helicopter flights sell out within hours. Outside peak season, a week is enough, sometimes even the day before.
When is the best time for activities in Reunion Island?
May to November is the dry season: settled weather, calm seas and the best visibility for diving and kayaking, with whale season on top from June to October. December to April is cyclone season: some sea trips may be cancelled, but it is the best time for canyoning (rivers running high).
What can I do in Reunion Island on a tight budget?
Glass-bottom kayaking (€50) and the lava tunnel (€50) are the two most affordable guided activities. Beyond that, the island has plenty of free things to do: hiking trails, lagoon beaches (Ermitage, Boucan, Saint-Leu), viewpoints (Maïdo, Cap Méchant) and free wild camping in certain authorised areas.
