The sea round Arran reaches depths of up to 120m(400ft). The effect of the North Atlantic Drift means that the water temperature is slightly warmer than you would expect for this latitude and ranges from about 6C in winter to 15C in summer.
The geology of the rocks, the action of the waves and the ebb and flow of the tide all combine to provide a variety of different beach habitats round Arran.
Smaller pockets of natural woodlands survive all over the Island, particularly along the sides of burns including those inside the forestry plantations.
Farmland provides remarkably diverse habitats for a wide variety of plants and animals. The majority of the farmland on Arran is focused on rearing livestock so there are plenty of grass meadows often rich with wild flowers as well as various types of grasses.
Arran’s mountains are some of the most dramatic to be found anywhere in Scotland. The mountains are a great place to see red deer, red grouse, meadow pipits, kestrels, peregrines and ravens.

A very large proportion of Arran is made up of open moorland which ranges in altitude from about 450m to close to sea level.
