Garden Route National Park: Island Lake boat launch site closed after fire!

South African National Parks (SANParks) has confirmed that the Island Lake boat launch site in the Wilderness Section of the Garden Route National Park in South Africa's Western Cape has been temporarily closed to the public following a boat fire incident on Monday, 05 January 2026.

According to preliminary information, a privately owned boat belonging to a park visitor caught fire while launch preparations were underway at Island Lake. Reports indicate that the vessel was already afloat when the engine was started, at which point it ignited. The exact cause of the fire has not yet been determined and remains under investigation.

Emergency response teams from SANParks were quickly on the scene, supported by the Wilderness Fire Brigade, who successfully contained the blaze and secured the surrounding area. While no fatalities were reported, one individual sustained injuries and was transported to a nearby hospital for medical treatment.

The incident resulted in minor damage to the jetty at the launch site. In addition, a fuel spillage occurred during the fire, prompting SANParks to appoint a specialist service provider to conduct environmental clean-up and remediation work to protect the sensitive wetland ecosystem of Island Lake.

In the interest of public safety and to allow for full rehabilitation of the affected area, SANParks has confirmed that the Island Lake boat launch site will remain closed until further notice. Visitors should note, however, that the Island Lake picnic area remains open and accessible.

Garden Route National Park: Island Lake reopens for recreation after blue-green algae closure!

South African National Parks (SANParks) has announced the reopening of Island Lake in the Wilderness Section of the Garden Route National Park in South Africa's Western Cape, effective today, 30 May 2025. The lake had been temporarily closed since 07 March 2025 due to the presence of blue-green algal bloom bacteria.
Recent water quality tests, supported by satellite imagery, have confirmed the absence of toxin-producing algae in the lake. This clearance deems the lake safe for all recreational activities, including swimming, boating, and fishing.
The blue-green algal bloom that led to the closure was likely the result of several environmental factors, including warm temperatures, decreased water inflows, and nutrient runoff from the broader catchment area. These factors are often beyond the control of SANParks.
SANParks has committed to continuous monitoring of Island Lake to detect any early signs of algal bloom resurgence or changes in water quality. As climate change and increased pressures on the landscape can contribute to future blooms, visitors are encouraged to stay updated through official SANParks channels.

This precautionary measure follows the detection of a blue-green algal bloom, which may pose a potential health risk.
SANParks is closely monitoring the situation while awaiting laboratory results to identify the algae species and determine whether it can produce toxins. Algal blooms in standing water are often influenced by environmental factors such as temperature changes, organic matter decomposition, bird activity, and recent freshwater inflows.
