Porterville is a country town that lies about 140km north of Cape Town. The Porterville Blue Crane Route links the various attractions in and around the town under the banner of Blue Crane conservation, as the route is one of four Blue Crane routes in the Western Cape. Blue Cranes, which are South Africa’s national bird, are found in the Swartland area (meaning ‘black land’ – an area which includes Porterville and was originally named as such by early explorers because of the dark renosterbos or ‘rhino bush’ that originally blanketed the area). The wheat crops in the region are ideal habitat for the birds.

Because the Swartland area and the Porterville surrounds in particular, are now home to the Blue Crane, the Overberg Crane Group has extended its conservation efforts into the area. This has given rise to the fourth Blue Crane route being formed. Blue Cranes are omnivorous and eat plant, grain and insect material, which is why the wheat lands and pasture systems here suits them so well. Nevertheless even here they face threats  including collisions with power lines and fences, misuse of agrochemicals, getting caught in baling twine, chicks drowning in water troughs and the theft of chicks for the pet trade.

Besides Blue Cranes, the Porterville region is famous for the rarest of flowers, the Disa Uniflora, and it is the only place in South Africa where one can see fields of these flowers in nature. The rarest of these is the sulphur-yellow Disa, which is found in one small colony in Porterville.

Conditions in summer are usually dry and hot with powerful thermals, making this the ideal location for paragliding enthusiasts to launch themselves off the Groot Winterhoek Mountains. Winters are quite severe, with snow often covering the mountain peaks and storms rolling in from the Atlantic Ocean.

The dramatic rock formations, fauna, flora and mountain rock pools in the Groot Winterhoek Wilderness Area make hiking here a pleasure. For the less adventurous, there are coffee shops, restaurants and the opportunity to stay on one of the local farms and experience the Swartland way of life. There are also a number of historical monuments in the area, a museum, a wine cellar, a golf course and numerous fresh water angling spots.   Accommodation on the route range from guesthouses to self-catering chalets and campsites.
