Ultimate Guide to Black Diamond Lake, Collie

Black Diamond Lake is the most visited attraction in Collie and a great destination for day trips from Perth, Western Australia.

Formally a mine site, Black Diamond Lake has become popular for its stunning turquoise colour created by the limestone in the water. It is becoming increasingly popular as a photography hot spot in Western Australia’s South West, and you can find lots of great photos of the lake on Instagram.

It is a great place to soak up the sun and have a swim with your family. So, pack a lunch and take a cute float and spend your day relaxing on the stunning blue water.

How to Get There

It takes approximately 2 hours to get to Black Diamond Lake from Perth, Western Australia.

While you can take public transport, via bus and train, to get to the Town of Collie your best option is to drive as Black Diamond Lake is located well out of the town. Not only is driving the easiest option, it is also much faster which is always better when travelling with kids.

If you are driving the signage is not very clear, so here are some easy to follow directions:

How to get to Black Diamond Lake:

  1. Take Ferguson Road, just off of the Coalfields Hwy

    If you’re coming from Perth, this will be a right turn. If you’re coming from Collie, this will be a left turn, about 5km out of town.

  2. Drive along Ferguson Road

    While you drive along Ferguson Road, the lake will be on your right. Continue on Ferguson Road for about 600m.

  3. Turn onto an unsealed road to find an area where you can park.

    The carpark will be to your right. It’s very obvious with a lot of parking space and easy access to the lake.

When to Go

Black Diamond Lake is continually attracting more tourists, becoming exceptionally busy during Western Australia’s summer time. However, despite the crowds, the summer months are a great time to visit Black Diamond Lake when you can enjoy a refreshing swim. The water is also its bluest on a sunny day!

If you are planning a trip to Black Diamond Lake during the tourist season, you should definitely head into the Town of Collie and contribute to the local economy there!

If you are looking to visit with less tourists, the shoulder seasons are a great option.

You can visit at the end of summer around March/April, before the weather starts to cool down. Otherwise, come when the weather starts to warm up in October/November!

Things to Do

The best thing to do at Black Diamond Lake is to soak up the sun and swim in the water. Pack a BBQ and some food and cook yourself some snags (sausages) for a classic Australian lunch. Take a cute float to relax on in the water and take some photos with!

There are also plenty of other things to do around Black Diamond Lake with your kids in both Collie and the Wellington National Park. So if you are looking for more activities to do with your family go check out my guide on the top things to do in Collie.

What to know before visiting

Formally an Open Cut Mine: Black Diamond Lake is formally an Open Cut Mine that ceased operation in the 1950s. It was then filled with water to act as a swimming hole for the local community. So, why is Black Diamond Lake blue? The water gets its amazing blue colour from the limestone rock that forms the base of the lake. 

Just note, there have been issues with the quality of the water. There is signage to indicate when there are dangerous levels of bacteria in the water.

No Facilities: There are no facilities located at the lake. However, during the peak season the shire may install temporary toilets for public use. This is a good thing to know if you are planning a trip to Black Diamond Lake with your kids!

Take Shade: There is plenty of natural shade around the lake, however it is located a little back from the water. Be sure to take some shade so that you can sit by the water in comfort! It is also handy to have your own, as on a busy day the shaded areas will fill up fast.

Take Something to Sit on: You should take something to sit on as the ground around the lake is quite hard and there is a lot of dirt. 

No Camping: You are unable to camp at Black Diamond Lake, however there is plenty of options for camping in the surrounding area. If you are hoping to stay the night, check out the section below on where to stay.

No Campfires: You CANNOT have a campfire at Black Diamond Lake.
