1. Cuevas de Mallorca (Caves of Mallorca)
Locations: Porto Cristo, Campanet, Artà & Palma
Rain outside? Go subterranean. Mallorca’s caves reveal an ancient world of stalactites, stalagmites and hidden lakes.
-
Cuevas del Drach, Porto Cristo: The best-known and busiest, home to Europe’s largest underground lake and a classical music concert that echoes through the caverns.
-
Cuevas dels Hams, Porto Cristo: Smaller but atmospheric, with hook-shaped rock formations and colourful light shows. Dinosaurland next door is an easy bonus stop.
-
Coves de Campanet, The quiet alternative. Self-guided, low-key and ideal for younger explorers.
-
Cuevas de Artà, Canyamel: Vast, dramatic chambers perched above the sea. Best for older children who don’t mind a few steps.
-
Cuevas de Génova, Palma: Small, local and right near the city – a great option without leaving town.
Not suitable for pushchairs, but fine for adventurous kids. Drach and Génova are reachable by public transport; others need a car.
2. Museu de Ciències Naturals de Sóller (MUCBO Science Museum)
Location: Sóller
A small but intriguing museum, packed with curiosities. Expect fossils, Tramuntana geology, and a collection of preserved animals. The showstopper is the world’s oldest mammal ancestor, discovered in Mallorca in 2024. It lived around 270 million years ago, long before the dinosaurs.
Join a MUCBO Explorer family tour if you can — they add stories and games that make the visit more interactive. When the clouds lift, head into the adjoining Botanical Gardens.

3. Els Calderers de Sant Joan
Location: Sant Joan, near Manacor
Step inside an 18th-century manor house frozen in time. Wander through kitchens and workshops filled with antiques, peek into old bedrooms and discover how Mallorca’s rural families once lived. Outside (when the rain takes a pause), children can meet the resident farm animals and roam the gardens. There’s also local food and wine tasting. It’s calm, interesting and easy to pair with a visit to nearby Manacor.

4. Palma Aquarium
Location: Palma
Always a crowd-pleaser, this is a safe bet whatever the weather. You’ll find Europe’s deepest shark tank, a hypnotic jellyfish tunnel and the Big Blue – an immersive screen experience that feels like diving without getting wet. Little ones love the Nautilus soft play area, and daily feeding sessions add a nice extra. Easy to reach by bus from Palma centre.

5. Aquari de Cabrera (Cabrera Aquarium & Interpretation Centre)
Location: Colònia de Sant Jordi
Compact but fascinating, this small aquarium doubles as the Cabrera National Park visitors’ centre. Explore colourful Balearic sea life and learn about the region’s protected ecosystems. You’ll only need about an hour, but it’s calm, educational and rarely crowded.
