Knysna sits on a tidal lagoon that is one of the most important estuaries in South Africa, and the only way to understand the place properly is from the water. This cruise leaves from the harbour at Thesen Island, runs across the lagoon past the town, the forested hills and the sandy shores, and carries on to the Knysna Heads, the two huge sandstone headlands that form the gateway to the Indian Ocean. The skippers share the story of the Heads, a passage with a reputation for treacherous currents that has claimed many ships, and point out birds, seahorse habitat and local landmarks along the way. The trip lasts about an hour and a quarter and is rated highly by reviewers on the booking page. It is a good first activity in Knysna because it gives you the lie of the land, and it is gentle enough for children and older travellers. The lagoon is calmer than the open sea, so the ride is smooth for most people, though conditions at the Heads can vary with wind and tide.
The route and what you see
You check in at the activity desk at the Thesen Island cafe, board the boat and head across the lagoon, passing the waterfront, the island's marina and the surrounding hills. Near the Heads the water changes character as the lagoon meets the sea, and the boat holds position to give you views of the cliffs, the rocks and, on a clear day, the swell breaking in the gap. The narration covers the history, the wildlife and the plants that grow in the estuary, and many skippers are happy to answer questions.
Choosing a time
Morning departures tend to be calmer, and late afternoon trips give warmer light on the cliffs. Sunset cruises and sailing options also run from Knysna, but this one is a straightforward scenic outing. Bring a hat, sunscreen and a windproof layer, because it is cooler on the water than on the quay, and wear shoes with grip for the boat.
Fitting it in
Knysna has plenty of good restaurants and craft shops around the waterfront, so a cruise followed by a lunch of local seafood is a classic half day. It also pairs well with a visit to the viewpoint at the Heads by road, to compare the two perspectives. Book ahead in the December and Easter holidays, when the departures fill up. If the weather is poor, the operator may reschedule, so check the cancellation terms when you book.
