How do Mauritius and Réunion differ?

They’re opposite holidays, 45 minutes apart. Mauritius is the beach island — lagoon resorts, warm swimming, a mountainous interior and a rich food culture, built for relaxing. Réunion is the mountain island — a roadless caldera, one of the world’s most active volcanoes, and world-class hiking on French soil, with barely a beach trip in it. Lagoon relaxation, or volcanic adventure. See the Mauritius and Réunion guides.

Which is for a beach holiday, and which for hiking?

Unambiguous: Mauritius for the beach (lagoon swimming, resorts, a gentle interior) and Réunion for hiking (the cirques, Piton des Neiges, the volcano). Réunion has only a thin, shark-restricted beach strip and isn’t a swim-and-laze destination; Mauritius isn’t a serious trekking one. Pick by whether you want to relax by water or climb mountains.

Do they really combine well?

Yes — it’s one of the great Indian Ocean pairings. A 45-minute flight links them, so you can do Réunion for the active, mountainous half and Mauritius for the beach half of a single trip, getting genuine variety without a long haul between legs. Their best seasons broadly overlap (both favour the cooler, drier winter), which makes the combination easy to time.

Which is easier and cheaper?

Mauritius is the easier beach trip and better value for a relaxing holiday, with a mature tourism economy. Réunion is French-priced (dearer) but effortless in a different way — euros, good roads, the ease of France — with the mountains themselves free to roam. Comfort and value, or French ease around wild terrain.

Mauritius vs Réunion

Two islands 45 minutes apart that offer opposite holidays. Mauritius is the beach: lagoon resorts, warm swimming, a mountainous interior and a rich food culture, built for relaxing. Réunion is the mountain: a roadless caldera, one of the world’s most active volcanoes, and world-class hiking on French soil, with barely a beach trip in it. Lagoon relaxation, or volcanic adventure — and because they’re so close, they pair beautifully.

The split

Lagoon, or volcano

Two islands 45 minutes apart offering opposite holidays — a beach, or a mountain.

Beach vs mountainthe tripLagoon resorts, or a volcano and roadless cirques

Relax vs hikethe paceDo-little by the water, or serious trekking

45 min apartthe linkClose enough to combine into one trip

Mauritius is the beach: lagoon resorts, warm swimming, a mountainous interior and a layered food culture, built for relaxing. Réunion is the mountain: a roadless caldera at Mafate, one of the world’s most active volcanoes, and world-class hiking on French soil — with only a thin, shark-restricted beach strip. Lagoon relaxation, or volcanic adventure; and because they’re 45 minutes apart, the choice can become a combination.

Operational detail — Mauritius’s €3/night fee, arrival form and interior sights; Réunion’s volcano access, post-cyclone trail status and shark-swim ban — lives on the two guides: Mauritius, know before you go and Réunion, know before you go. This page is the head-to-head.

Who suits which

Who each actually suits

Beach-relaxation or mountain-adventure — so these never invert.

If you want…	Mauritius	Réunion
A beach and lagoon holiday	Wins clearly. Built for it	A thin, restricted strip
Serious hiking and a volcano	Gentle interior only	Wins clearly. World-class
Relaxing and do-little	Wins. Resorts and lagoon	Active by nature
Dramatic mountain scenery	Some peaks	Wins. Cirques and crater
Value for a relaxing trip	Wins. Good value	French-priced
Warm swimming	Wins. Safe lagoons	Shark-restricted

Doing both

A great pairing: mountain then beach

Just 45 minutes apart — this is the rare case where doing both is the smart move.

Because they’re a 45-minute flight apart and offer genuinely different things, Mauritius and Réunion make one of the Indian Ocean’s best twin-centre trips: run Réunion for the active, volcanic half and Mauritius for the beach half, and you get real variety without a long haul between. Their seasons broadly align on the cooler, drier winter, so the combination is easy to time. If you only have time for one, pick by whether the holiday is to relax or to climb.

What we leave out

What we deliberately leave out

Exact prices and the moving pieces — Mauritius’s nightly fee and sight prices; Réunion’s car hire, refuge and volcano/trail access — change within a season, so the figures here are the shape of the gap, not a quote; the country guides carry the live detail.
