The Queensland Government says it will upgrade a scenic walk on Magnetic Island off Townsville, in the state's north, with work due to start next week.

The historic four-kilometre Forts Walk, with views to the ocean, will have its track repaired and have signage installed.

Parks Minister Steve Dickson says the Government is spending $400,000 on the project to boost tourism.

"We spent $400,000 at Mt Coolum which is down on the Sunshine Coast in the last 12 months and the amount of people now visiting that area has almost increased by 50 per cent," he said.

"So if we get the same drawcard and appeal created up on Magnetic Island, I think the outcome's going to be fantastic."

Mr Dickson says the park surrounding the track is home to koalas and could attract a lot more visitors.

"It's about tying a lot of the historical sites together but also about giving people the opportunity to have a walk around Magnetic Island, nice and safely and get a look at what out parks have to offer because we've got some of the best views in the world and some of the best fauna and flora to look at also in the world," he said.
