Holy Loch Nature Reserve comprises around 24 acres of ungrazed saltmarsh, wild flower meadow and woodland, with reedbed and bog. These are intersected by several burns. Over 20 small pools on the marsh support an array of water plants and animals.

The reserve is home to at least 1000 plants, animals, fungi and many other types of organism. 

An easy path to an accessible birdwatching hide, with bird feeders, makes the reserve suitable for anyone. Over 120 species of bird use the reserve during the year, including Kingfisher, Osprey, Little Egret and Peregrine. Occasionally, a White-tailed Eagle overhead may spook the birds below, and cause them all to take to the air. Small populations of Curlew, Redshank, Teal and Wigeon overwinter around the loch before heading for their breeding grounds in late Spring and Summer.

The best time to visit is 1 hour either side of high tide.
