Es Trenc is the most famous beach in Mallorca and is mentioned in many books as one of the most beautiful and most well-kept in Europe, as it's the last big, scenic beach not spoiled by huge hotels and noise from restaurants and bars. Worth mentioning is that there's no city attached to Es Trenc - a factor that tends to bother some people, where others consider it to be one of the absolute strengths of the beach.
The beach is located in a national park and reserve, having more than 2 km of the finest sand and crystal clear, turquoise green water. Very special for visiting Danes is that you find dunes at the very back of the beach - just as the Scandinavians are familiar with from the North Sea. Be aware that you have several sections for naturists, and that it's said to be the most visited nudist beach in Mallorca.
The beach is very child friendly with its lovely sand and water, but you have no possibility to rent equipment of any kind.
