Free Things to Do in Cairns

You don’t need a big budget to enjoy everything Cairns has to offer. From relaxing by the lagoon to exploring lush rainforest trails, this tropical city is filled with incredible free experiences for locals and visitors alike. Here’s your ultimate guide to making the most of Cairns—for free!

🏖️ Relax at the Cairns Esplanade Lagoon

This sparkling saltwater lagoon is the heart of Cairns and a favourite spot for locals and travellers. Overlooking Trinity Inlet, the Cairns Esplanade Lagoon is free to use and perfect for swimming, sunbathing or enjoying a picnic under the palm trees. Lifeguards are on duty daily, and there’s even a sandy beach section for the little ones.

🚶‍♀️ Stroll the Cairns Esplanade Boardwalk

Stretch your legs along the scenic Esplanade Boardwalk, which runs parallel to the ocean and offers shady trees, exercise stations, birdwatching opportunities and public art installations. Sunrise and sunset walks are especially magical, with views over the water and distant mountain ranges.

🐦 Go Birdwatching at the Cairns Mangrove Boardwalk

Explore a different side of the tropical city at the Centenary Lakes and Mangrove Boardwalk. This peaceful walk lets you wander through unique ecosystems and spot native wildlife, including colourful birds and curious mudskippers. It’s a serene, shady retreat close to the city centre.

🎨 Discover Public Art and Murals

Cairns is full of creative surprises, from large-scale murals to interactive sculptures. Walk through the city streets to find works by local artists that celebrate the region’s nature, heritage, and Indigenous culture. Keep an eye out for art trails near the Esplanade, Shields Street and around Munro Martin Parklands.

🌿 Enjoy a Rainforest Walk at the Botanic Gardens

The Cairns Botanic Gardens are a hidden gem just five minutes from the city. Entry is free, and you’ll find tropical plants, beautiful walking tracks, and the peaceful Rainforest Boardwalk. For the adventurous, the Red Arrow and Blue Arrow tracks behind the gardens offer panoramic views over the city and coast.

🎒 Hike to Crystal Cascades

For a refreshing rainforest escape, head to Crystal Cascades, a series of freshwater swimming holes tucked into the foothills of the Barron Gorge National Park. The walk is flat and easy, and the cool, clear water is the perfect reward. It’s a local favourite for families, walkers and nature lovers.

🌅 Catch a Sunrise or Sunset

Cairns is perfectly positioned for magical sunrises over the Coral Sea and golden sunsets behind the mountains. Head to the Esplanade, Fogarty Park, or even the Red Arrow Lookout for unforgettable views—and some seriously Insta-worthy moments.

🛍️ Wander the Cairns Markets

While it’s tempting to shop, wandering through the Rusty’s Markets (Friday to Sunday) or the Cairns Night Markets is an experience in itself. Enjoy the colourful displays, soak in the tropical vibe, and sample a few free tastings at local produce stalls. It’s a great way to meet local makers and feel the community spirit.

🐠 Visit the Cairns Aquarium Reef Tank (Front Foyer)

While entry to the full aquarium requires a ticket, you can peek into the giant reef tank from the front foyer for free. It’s a fun little stop if you’re in the city and curious to see marine life up close.
