The common brown water snake (Lycodonomorphus rufulus) is a species of nonvenomous South African snake. This gentle, harmless snake is by far the most common water snake in southern Africa. It can be found from Cape Town in the south, along the wet east coast of South Africa and inland as far as Gauteng, Lesotho, and Zimbabwe. Throughout its range, its natural habitat is water margins, where it shelters under leaves and logs. It emerges at night to hunt frogs and sometimes rodents. It lays up to 10 eggs at the end of summer.

With luck
About 10% of wildlife watchers report a Common Brown Water Snake sighting in Garden Route National Park on a given day, based on 47 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 35 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
February
In that month about 30% of wildlife watchers report a Common Brown Water Snake in Garden Route National Park on a given day, against under 5% in June and August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Brown Water Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Common Brown Water Snake sightings, Garden Route National Park ranks 2nd at about 10%. The best odds are in Table Mountain National Park (South Africa, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Brown Water Snake is recorded against all the reptiles logged in Garden Route National Park (47 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
