Blue Lake

In the heart of Canberra's Namadgi National Park, Blue Lake is a striking glacial tarn that rewards hikers with its vivid turquoise water and dramatic granite backdrop. This pristine alpine lake, formed thousands of years ago, sits at an elevation of around 1,400 metres and offers a serene escape from the city bustle. The lake's intense colour, caused by fine rock flour suspended in the water, changes with the light and seasons, making every visit unique.

Highlights & What to See

• Hike to Blue Lake: The 5.5 km return walk from the Mount Ginini car park is moderately challenging, winding through subalpine woodland and across granite outcrops. Allow 2–3 hours, and keep an eye out for kangaroos and wedge-tailed eagles.
• The Lake's Colour: The startling blue-green hue is best seen on sunny days; the water reflects the sky and the surrounding granite, creating a painterly effect.
• Nearby Peaks: For experienced hikers, combine the lake visit with a climb to the summit of Mount Bimberi (the ACT's highest point) or Mount Gingera for panoramic views.
• Wildflowers: In spring (October–November), the trail is dotted with snow gums, alpine grevilleas, and billy buttons.
• Photography: Early morning or late afternoon light casts long shadows and intensifies the lake's colour – bring a polarising filter.

Suggested Time to Spend

Most visitors allocate a half-day for the Blue Lake hike, starting early to avoid afternoon storms. Combine it with a picnic lunch at the lake or at the nearby Mount Ginini picnic area. If you're short on time, a quick walk to the lookout near the car park still offers a glimpse of the lake, but the full hike is highly recommended for the immersive experience.
