A walk in Halle Woods is a must all year round, but between mid-April and early May, it's even more special. At this time, the bluebells are in bloom. These spring flowers create a magnificent purple carpet. It depends on the weather, of course, but fortunately lasts for two or three weeks. This gives you plenty of time to admire the carpet of flowers.
