The Lim bay is one of the most beautiful places in Istra, legally protected as a significant landscape and a specific marine reserve. It is a sunken karst valley with specific vegetation and marine landmarks. It was developed in limestones, with approx. 10 km length, 600 m average width and canyon sides up to 150 m height.
The sides of the bay are overgrown with all characteristics of holm oak (Quercus ilex L.), mock privet (Phillyrea latifolia L.), strawberry tree (Arbutus unedo L.), laurustinus (Viburnum tinus L.), Mediterranean smilax (Smilax aspera L.), mastic (Pistacia lentiscus L.), oriental horn beam (Carpinus orientalis Mill.), manna ash (Fraxinus ornus L.). The microclimate conditions the growth of submediterranean community of downy oak (Quercus pubescens Willd.) and Turkey oak (Quercus cerris L.)
A diversity of vegetation in such narrow area represents the unique ecological rarity. Specific properties of the sea cause and condition the richness of flora and fauna with exceptional communities that cohabitate on the sea bottom. Due to its many underwater springs, the sea water is of decreased salinity, which varies depending on the time of the year and the depth. The sea is of less transparency, indicating an abundance of planktons. There are noticeable changes in temperature as well as high oxygen concentration. Such specific properties determine richness of flora and fauna of the sea with exceptional communities of the sea bottom. The area is a natural breeding spot for certain species of fish. There is a well- known mussel and oyster farm, which can be tasted at some of the restaurants nearby.
Lim bay as a movie set
In the mid-twentieth century the Lim bay was a suitable film set for shooting films about Vikings. In 1958 a film called Viking was shot there, with Kirk Douglas and Tony Curtis in leading roles. Even a small Viking settlement was made there; it also appeared in another film called Long Boats ten years later, in 1968. The Lim Bay was presented as a fiord, this is why it is sometimes called Lim Fjord!
