Harbour to Headwater Biodiversity Trail

The Avoca River which flows into Arklow has its origins in the Wicklow Mountains, with many tributaries such as the Glenelo, Glenmacnass, Avonmore, Avonbeg, Derry, and Ow Rivers all coming together to flow into the Irish Sea at Arklow. A new Harbour to Headwater Biodiversity Trail explores this catchment area highlight the magnificent and varied local wildlife and the significant wealth of flora and fauna that exist on both the land and in the water.

In 14 locations across the region from the Harbour in Arklow right up along the river catchment to the Headwaters of Glenmalure, you can find information panels specific to each of those points on the River network. In addition, an online interactive resource provides more information on local biodiversity with the option to take part in citizen science activities. You can look out for and identify aquatic insects (macro-invertebrates) and learn which are more sensitive insects, such as mayflies, and how they are intrinsically linked to water quality.

Find the main Information Panel outlining the Harbour to Headwaters Biodiversity Trail in Arklow Town before you choose which of the three trails you would like to undertake!
