The Forts Walk is one of Magnetic Island’s most well-loved tracks, offering a mix of natural beauty, local wildlife and fascinating wartime history, all within a relatively short and accessible hike. At around four kilometres return, the walk usually takes about an hour and a half to complete, with a gentle climb that steadily reveals more of the island’s character as you go.
The trail begins by winding through dry woodland dominated by eucalypts and acacias. It’s a good idea to slow your pace and keep an eye on the treetops here, as koalas are often spotted nestled in the branches, especially in the more stunted trees common to this part of the island. The track itself is well-formed and easy to follow, with interpretive signs along the way sharing insight into the area’s flora, fauna and wartime significance.
As you gain elevation, the path leads through a landscape shaped by time and geology. Granite boulders sit quietly among hoop pines, framing sections of the walk with a kind of understated drama. Near the top, the remains of World War II fortifications come into view. These concrete structures, now weathered but still solid, once played a role in Australia’s coastal defence network. They are among the best preserved in Queensland and are now heritage-listed. Information displays around the site help paint a picture of life here during the war, giving voice to the men and women who once served on the island.
The real payoff comes at the summit, where the views open up in all directions. On a clear day, you can see across to Bowling Green Bay National Park in the south and, to the north, the Palm Islands and Hinchinbrook Island National Park. It’s a place to linger, take in the scene and appreciate the contrast between the island’s quiet present and its active past. Whether you're drawn by the chance of seeing a koala, the history, or the far-reaching ocean views, the Forts Walk offers a rich and memorable experience that captures the essence of Magnetic Island.
- Start your walk early in the day to enjoy cooler temperatures, better chances of spotting wildlife like koalas, and easier access to parking.
- Take care on the final section of the walk, where the Forts circuit becomes steep with numerous steps and uneven surfaces. Proper footwear and a steady pace are recommended.

Getting to the trailhead: Magnetic Island National Park.
To reach Magnetic Island National Park, take a 20-minute ferry from Townsville, departing near Breakwater Marina. Once on the island, the Forts Walk begins at the Forts Junction, which sits on the main road between Arcadia and Horseshoe Bay. The junction is a central point in the island’s walking trail network and is accessible by car, bus or on foot. While there is a small car park off the sealed access road, spaces fill quickly, especially during peak times, so walking or taking the island bus is often the best option. You can also access the Forts Junction via scenic walking trails: it’s 6.4 km from Nelly Bay, 3 km from Arcadia, or 2.3 km from Horseshoe Bay.

Magnetic Island, known traditionally as Yunbenun, is a striking mix of granite headlands, open woodland, and coral-fringed beaches just offshore from Townsville. Once connected to the mainland, it became an island around 7,500 years ago when sea levels rose. Today, about 78% of its 5,184 hectares is protected as national or conservation park, preserving its distinctive natural and cultural heritage.
The island’s vegetation is mostly open eucalypt woodland, with bloodwoods, stringybarks, and ironbarks dominating the landscape. Hoop pines rise from rocky headlands, vine-thickets cluster in gullies, and the coastline is fringed with mangroves, seagrass beds, and coral reefs. These diverse habitats support a wide range of wildlife. Sea turtles nest on sandy beaches, dugongs and green turtles feed in the seagrass, and rock wallabies shelter among the granite tors. Koalas are often spotted in the trees, and the calls of bush stone curlews echo through the woodland.
The Wulgurukaba people, the ‘canoe people,’ have long maintained a deep connection to Yunbenun. Evidence of their presence, including middens, tools, and art sites, can still be found. Since being named by Lieutenant James Cook in 1770, Magnetic Island has had a layered history involving logging, agriculture, wartime defences, and tourism. The World War II fortifications remain among Queensland’s best preserved examples.
The island’s landscape tells a much older story. Around 275 million years ago, granite pushed to the surface and slowly weathered into the dramatic boulders and tors we see today. Fault lines formed gullies and valleys, shaping the island’s rugged topography. Combined with its shallow surrounding seas and rich biodiversity, Magnetic Island offers a unique blend of geology, ecology, and history, making it a compelling destination for hikers and nature lovers alike.
