‘We hiked green volcanoes near Barcelona’: readers’ favourite day trips from cities

Our tipsters revel in rural escapes and dips in the sea on their city breaks from Gdańsk to Lisbon

After a couple of days exploring beautiful Salzburg, I bought a hop-on, hop-off bus ticket to the Austrian lake district – the Salzkammergut. The hotel receptionist recommended we headed to Fuschl am See. The hourly bus took about 40 minutes to get to this absolute gem. The lake water – perfect for summer swimming – is so clean it is officially drinkable. There are also charming guesthouses and small hotels. It is an absolutely beautiful spot and the whole area should be explored.
