Menorca absolutely isn’t Ibiza or Mallorca but there’s still plenty enough to do for a holiday. DH and I go most years.
There’s loads of restaurants around the marina in Cala N Bosch and different bars. Someone is usually playing the guitar in the square and you’ll find children, and sometimes adults, dancing while their parents are eating in the adjacent restaurants or having a drink in the bars. Cala N Bosch is close enough, about 15 mins, to Ciutadella too so you can get a taxi or a bus (although we hire a car) to go there for the evening.
Cala Galdana is my favourite beach on the island. There’s some lovely restaurants there too, but it does get very busy because it’s so beautiful.
Son Bou is very nice and popular and has the longest beach on the island.
Cala N Forcat is probably the most touristy area in Menorca, tbh, but it’s probably the most lively too.
Menorca is great for families. The beaches are really safe, the sea is great for snorkelling, it’s incredibly beautiful and everyone is really friendly.
