Crystal Summer, formally known as Crystal Lakes & Mountains, is a part of TUI Travel PLC, the largest holiday company in Europe. Our holidays are set amongst some of Europe's most stunning locations - with awe-inspiring mountains, beautiful beaches and peaceful lakes as a back-drop to your fantastic summer holiday.
We aim to make it easier when picking your accommodation by including a Crystal ratings guide. The Crystal ratings take into account the general standards of the destination, facilities, location and character of the accommodation. As well as the Crystal ratings, some of our accommodations come recommended by our customers. Crystal Gold Awards are awarded for overall excellence, as rated by customers who stayed there. It makes choosing your holiday that little bit easier.
