Lough Ramor is a large, shallow glacial lake of approximately 741 hectares situated near the town of Virginia in County Cavan, Ireland. The lake measures roughly 4 miles in length with an average width of half a mile, and sits at coordinates 53°49′N 7°5′W. Its average depth is around 3 metres (approximately 6 feet in summer), with a maximum depth of around 5.5 to 6 metres. Despite its generally shallow character, there is at least one significant drop-off reaching approximately 54 feet located in the upper part of the lake, accessible only by motorised boat. The shallowness means numerous unexpected shoals exist throughout, and paddlers should exercise caution when navigating the lake. The lake has a pH of 7.5 and is periodically subject to algal blooms due to nutrient enrichment, which is worth considering when planning a trip.

The River Blackwater both flows into and out of Lough Ramor, which sits within the broader River Boyne catchment. The lake is a proposed Natural Heritage Area and is connected to a Special Area of Conservation under the Natura 2000 programme. Much of the shoreline features semi-natural woodland of alder, willows, and hazel, and the lake's islands are largely covered in willow. The surrounding landscape includes areas of mixed woodland, and the lake sits on Silurian strata that gives it a distinct appearance compared to other Cavan lakes. Wildlife on and around the lake includes whooper swans, mallard, red-breasted merganser, great crested grebe, black-headed gull, treecreeper, long-tailed tit, and occasional barnacle geese.

The Ramor Watersports Club is based at the Lakeside Manor Hotel on the Dublin Road in Virginia and is open daily from 9am to 7pm, offering sailing, waterskiing, and motorboat activities. The club has a marina and a wheelchair-accessible boat available for hire. A caravan and camping park is located at Ryefield, approximately 5km south of Virginia and 500m off the N3, situated on the lake's shores and offering boat hire. Virginia College also provides a boat launch point. The lake is well known for pike and coarse fishing, which means anglers with boats are a regular presence on the water and paddlers should be aware of shared use.
