Portrunny Harbour is situated on the Shores of Lough Ree. Lough Ree is the fifth largest lake in Ireland. Lough Ree is the second largest lake on the River Shannon. The River Shannon is 259km in length originates in the Cuilcagh Mountains in County Cavan and enters the Atlantic Ocean just below Limerick City.   The lake lies in an ice-deepened depression in Carboniferous Limestone. Some of its features are based on glacial drift.   Lough Ree is notable for numerous interesting islands, including  Inchcleraun (Quaker Island).  St. Diarmuid’s holy  well and  Abbey were founded in 540AD.   The holy well  is  located here and it is said that  St Diarmuid  often stopped in Portrunny on the way to the sanctuary of Inchcleraun where the ruins of seven churches can still be seen .

Portrunny is popular as a  recreation destination and a wonderful environment to observe flora and fauns. Portrunny has mooring facilities, a children’s playground, picnic tables; and is a popular resort in the summer months for walkers and tourists.

The name Portrunny is Port Reanna in Irish. The name derives from Port Air Cinneach, meaning lay person in charge of a the monastery. Portrunny bay was also called Cruit Bay in the past. It is bordered by Rinanny and Cruit Point two peninsulas on the lake.  On the south side of Cruit Point is the adjacent Gailey Bay and on the north side of Rinanny point is the River Hind. This divides the area of Ballymurry from Kilteevan.

Portrunny is 8km from Roscommon Town, whith a hinterland population of approx..563 (Source: Census 2011).  According to Roscommon Development Plan 2014-2020 the town and environs has experienced a high level of population growth in recent years, and this growth pattern is anticipated to follow on for further years ahead.  The plan further recognises the need to make adequate provisions to accommodate the health and recreational needs of a growing population including those with disabilities.

Portrunny is the nearest waterway amenity to Roscommon Town and requires significant investment to meet the required accessibility standards for all users.  As the area is in use continuously through the year, it not only attracts local visitors but also tourists form throughout Ireland and abroad, at times increasing the numbers there to several hundred.  There is potential for enhancing the aesthetics along with the safety of the area.

There is diversity of population in both local and other users in ages, abilities and interests. There is need for general improvements to enhance the amenities for the benefit of local, regional and international people who live, work, play, recreate, and walk, cycle, drive and boat here.
