You might think that once you’ve seen one cave, you’ve seen them all. Then you discover the Coves de Sant Josep, home to Europe’s longest navigable underground river — and realise that it’s right here in Spain, in La Vall d’Uixó. Visits take place by boat and in groups. The site’s staff expertly propel the boats through the tunnels and chambers in single file — and when they tell you to duck, make sure you do. At one point, you’ll be asked to continue on foot for around 250 metres before boarding the boat that will take you back to the exit. Make the most of the walk to admire the extraordinary formations in this geological museum up close.
For the more adventurous, there is also the option of exploring the river by kayak. The activity takes place in a group with a guide — and yes, be prepared to get wet.
Where to stay: just an eight-minute drive from the Coves de Sant Josep is our Sercotel Hotel Plana Suites. With its versatile range of rooms, you’ll find the perfect option for your type of trip, whether you’re travelling as a couple, with family or with friends. The choice is yours.
