The best time to go to Glenarm is during the summer months, from June to August, when the weather is at its most pleasant.During this period, you'll experience longer daylight hours and milder temperatures, making it ideal for exploring the Antrim Coast and Glens. This allows for comfortable walks around Glenarm Castle's Walled Garden, a key attraction, and leisurely drives along the scenic coastal road.Couples often find this time great for a romantic getaway. The warmer weather enhances the enjoyment of outdoor activities, such as exploring the local walking trails or enjoying a picnic with views of the sea. Many of the local cafes and restaurants also have outdoor seating options that are more enjoyable when the weather is good.For families, the summer offers the best opportunity to engage in outdoor adventures without the worry of inclement weather. Children can enjoy the open spaces around the castle, and boat trips or visits to nearby beaches are much more appealing when the sun is shining.
