Porterville Paragliding - Winter snow on the Groot Winterhoek Mountains.

The Bergrivier features a diversity of dramatic seasonal terrains, from high altitude mountains and deep valleys to extensive flatland plains interspersed with wine estates, fruit farms and olive plantations.

Winter months bring an unexpected alpine look with snow often dusting the peaks of the Groot Winterhoek Mountains rising behind the front ridge.

Springtime flowers bring an array of colour to the countyside while the summer sun gradually transforms the green landscape to warm golds and then to browns.
