Every year in August and September, the Cedarberg Wilderness Area is transformed into a floral showcase. Swathes of wildflowers cover the ground as far as the eye can see and over 250 different types of indigenous flowers have been documented in the area. The preceding winter’s rainfall strongly influences how abundant the Spring display will be. For visitors wanting to follow one of the many ‘Flower Routes’ on offer at this time, information is available from the Clanwillian Information Office.

Flowers are best viewed between 10 and 15:00, when the sun is at its warmest; be warned though that on misty or rainy days, most flowers remain shut. A feature of note is the annual 10-day Wild Flower Show presented by the Clanwilliam Wild Flower Association in the Old Dutch Reformed Church, a building that was declared a National Monument in 1978. Volunteers work together at the end of August to create a floral wonderland comprised of more than 360 different types of flowers. This outstanding flower fete includes concerts, art and food stalls, and a carnival.

Fynbos in the Cedarberg is of the Mountain Fynbos type, being characterized by heather, grasses, reeds and shrubs such as proteas and conebushes. Trees are scarce, being found mainly in groups along rivers and small watercourses. The Clanwilliam cedar is specific the this area; other trees include the wild olive and the mountain cypress. Aloes are common too.
