Four springs are found on the property. Each of these feed their own streams which eventually join up with each other and flow into the Witpoort River at the southern end of the farm. The Witpoort River is a tributary of the Olifants River.
Three waterfalls are present on the farm. The first, Pam’s Pool, is up along the stream that feeds into the southern end of Meike’s Mere. The second waterfall, Bald Ibis Waterfall, can be found past Matuka Dam on the way to the river, and the third waterfall, River Waterfall, flows into the Witpoort River.
A walk along any of the streams or the river will reveal a number of deep pools, rapids and coves.
There are two man-made dams on the property: Meike’s Mere and Matuka Dam, and one weir: Williams Favourite. Each of the dams has created wetlands at their inlets and outlets, providing good bird watching opportunities.

Unique to the farm is the large stand of Protea trees that can be seen from the road down to the river. For the energetic, a number of tree ferns can be seen along the streams. Small tracts of indigenous forest can also be found in some of the kloofs and at the waterfalls.
