The steady stream of visitors started arrived last night for The West Australian Great WA Bike Rider, with the Tent City at the Manjimup Timber and Heritage Park steadily filling up.

Visitors took the opportunity of an early arrival to get out and explore the town and surrounding attractions.

Manjimup Visitor Centre manager Roy Piggott and his staff of volunteers were kept busy giving directions and recommending places to visit.

Mr Piggott said the Diamond Tree was proving to be popular, with early visitors wanting to cycle out and climb the tree before it became crowded.

One early arrival was Garry Long from Bendigo in Victoria, who camped in Manjimup on Thurday night and was reassembling his bike before riding into town.

``We flew over yesterday and got a bus down,'' Mr Long said.

Mr Long has been to WA before, but was looking forward to seeing the South West scenery from his bike during the nine-day ride.

``The big advantage of this trip is you can see so much more travelling at a slower pace,'' Mr Long said.

``You can see a lot more than you can if you zip past in a car.''

He said he had been impressed with the welcome to Manjimup, and everyone had been very hospitable and friendly.

``It's starting off as a great experience from day one,'' Mr Long said.

Darryl Dimmick and Leeane Milne from Queensland said they were enjoying the sunshine.

``We came for the sunny weather!'' Mrs Milne said.

They were also getting ready to explore Manjimup ahead of the start of the event, planning to have lunch at The Wine and Truffle Company.

``I haven't tried truffle,'' Mrs Milne said.

The Manjimup Chamber of Commerce warned local businesses to be ready for the influx of visitors expected for the event.

``There's going to beclose to 1500 people here for this event on the day,'' said the chamber's Rose Moyle.

Even the Manjimup CWA was lending a hand, offering light lunches and morning teas to the cyclists.
