Situated only a two-hour drive from Perth, Black Diamond Lake is located five kilometres west of the coal mining town of Collie and is considered by many as the number one swimming hole in Perth.
Black Diamond Lake is an abandoned mine site that was de-commissioned in the 1950s and filled with water creating a stunning lake that sparkles and radiates a magnificent blue colour, making it some of the bluest water you will ever see.
Why is Black Diamond Lake blue?
While there doesn’t seem to be a definitive answer, reports state that the water is believed to be so blue because of how light reflects off the limestone rock that forms the base.
No matter why it’s still stunning.
Best things to do at Black Diamond Lake
The magical blue lake is perfect for a dip, SUP, canoeing and kayaking.
The lake has also become extremely popular with visitors bringing inflatable floats, because who wouldn’t want to simply lay back and enjoy the beauty of the lake and its surroundings?
Also please note that it can become quite busy and crowded in the warmer months — so it is recommended that you try to get there earlier in the day to avoid potential crowds and to find yourself a shady spot under the trees.
If you are going to setup a picnic spot for the day – be wary of bull ants.
Can you swim at Black Diamond Lake?
Swimming is permitted though there are signs warning people to swim at their own risk.
Camping and facilities at Black Diamond Lake
While camping isn’t allowed at the lake — for the best camping locations nearest to Black Diamond Lake we recommend another stunning blue lake in Stockton Lake just 8km east of Collie.
There are also no facilities (that means no toilets) and limited rubbish bins so ensure you don’t leave any rubbish behind.
Health warnings
Please note there have been previous health warnings at the lake.
Microbiological testing is performed from November to May each year as is the time of year when the water temperature is higher and therefore represents a higher level of risk to the general public.
It is recommended that you check with the Collie Shire water quality page for the latest water tests.
