18km Map & Elevation
The 18km trek is a great fitness challenge, takes approximately 5 hours to complete, and highlights the breathtaking trails and panoramic views of Magnetic Island.
Beginning in Nelly Bay, participants will experience a stunning vista over Geoffrey Bay before making their way to the WWII Forts. The route continues down to Florence Bay, before the climb begins to the Nelly Arcadia Trail. The course then follows the Nelly Bay coastline leading back to the finish line party at Nomads.
Please note: The Great Island Trek courses are subject to change. We attempt, at all times, to adhere to the advised course map. However, there may be circumstances beyond our control (high tides, fallen trees/branches, other safety aspects as advised by QPWS) that require us to slightly alter the course. If this is the case, the course changes will be clearly marked and identified on event day.

Keep Magnetic Island Prestine
The Great Barrier Reef is the world’s largest World Heritage area and stretches almost 2000km along Queensland’s coastline. The World Heritage status protects more than the reef—it also includes the area’s islands, which is further protected as national parks.
Their World Heritage listing means the islands and reefs are internationally important. However, the isolation and small size of Magnetic Island makes it vulnerable to pest impacts.
Let’s keep our trails magic and protect Magnetic Island’s National Park biosecurity
-
Pests can easily hitch a ride with people.They can hide in luggage, camping equipment, hydration packs, supplies and even on your clothes and shoes. Make sure you don’t carry pests next time you visit a Great Barrier Reef island.
-
Ensure your clothes are seed-free before you arrive on an island. Don’t forget to check your socks, pockets and hook and loop fastening strips such as Velcro.
-
Stay on the marked walking tracks to avoid spreading weeds across the island.
-
Leave no trace, please take all rubbish with you, and discard at one of the many rubbish and recycling bins available on the island.
