Many of the customs described by MacNeill and by medieval writers were being practised into the modern era, though they were either Christianized or shorn of any pagan religious meaning. Many of Ireland's prominent mountains and hills were climbed at Lughnasadh. Some of the treks were eventually re-cast as Christian pilgrimages, the most well-known being Reek Sunday—the yearly pilgrimage to the top of Croagh Patrick in late July. Other hilltop gatherings were secular and attended mostly by the youth. In Ireland, bilberries were gathered and there was eating, drinking, dancing, folk music, games and matchmaking, as well as athletic and sporting contests such as weight-throwing, hurling and horse racing. At some gatherings, everyone wore flowers while climbing the hill and then buried them at the summit as a sign that summer was ending. In other places, the first sheaf of the harvest was buried. There were also faction fights, whereby two groups of young men fought with sticks. In 18th-century Lothian, rival groups of young men built towers of sods topped with a flag. For days, each group tried to sabotage the other's tower, and at Lughnasadh they met each other in 'battle'. Bull sacrifices around Lughnasadh time were recorded as late as the 18th century at Cois Fharraige in Ireland (where they were offered to Crom Dubh) and at Loch Maree in Scotland (where they were offered to Saint Máel Ruba). Special meals were made with the first produce of the harvest. In the Scottish Highlands, people made a special cake called the , which may have originated as an offering to the gods.
