The Corrib system in County Galway, Ireland, comprises two distinct paddling environments: Lough Corrib, the largest lake in the Republic of Ireland at approximately 170 square kilometres, and the River Corrib, which drains the lough southward through Galway city to Galway Bay. The river is among the shortest in Europe at only six kilometres in length.

Lough Corrib contains over 1,000 islands and islets, with estimates of the total count reaching well over 1,300, though local lore often cites the more convenient figure of 365. The lake is oriented roughly north-south, stretching approximately 45 kilometres in length, with a notably narrow middle section near Knockferry. The lakebed features numerous limestone reefs that present a genuine hazard to paddlers and boaters; Irish Waterways has installed a system of marker buoys to assist navigation, and these should be followed carefully. The open water sections of the upper lake can expose paddlers to significant wind and wave conditions, and the combination of exposed water and submerged rocks demands careful attention to weather before setting out.

Access points include Knockferry, situated roughly midway along the lake's length, and Cornamona Pier on the western shore near Clonbur. Guided kayaking and sailing tours operate from Clonbur and from the Cornamona area. The River Corrib, running through the centre of Galway city, is popular with local whitewater kayakers as well as rowing clubs and recreational craft.

A typical lake paddling route involves island hopping, navigating rocky and reedy channels, and crossing sections of open water. Inchagoill is noted as the largest true island in the lake not connected to shore by causeway. The surrounding landscape reflects the broader Connemara character, with diverse wildlife including otters, hawks, bats, stoats, mink, and frogs, as well as brown trout and Atlantic salmon in the water. The lake is well regarded for its mayfly hatches, particularly in late spring and early June.

The lake is accessible year-round, though paddlers should monitor local weather and daylight hours carefully given the potential for rapid condition changes on open water.
