One of the best towns to see wildflowers is Mullewa.

One of the best for views and wildflowers is the 2.4km loop, Mullewa Bushland Trail. It starts and finishes at the Mullewa Scenic Lookout. The winding loop takes you along an, at times rocky, but not too steep hike with some small caves in rocky outcrops.
There are good views of the surrounding farmland and town. Interperative signage in places explains the indigenous culture of the area. When winter rains are good, the spring wildflowers are absolutely sensational. Besides carpets of everlastings, there are numerous other species.
It is 2.37kms long and will take you approx 40 – 60 minutes. The difficulty is rated as moderate. See these links for a Map and Waypoints.

The Northern Loop (115km) + The Southern Circuit (145km) - Scenic Drives
Two newly-developed drive trails are available from Mullewa, The Northern Loop and The Southern Circuit which take in the area’s natural beauty, outlying areas and unique historical and geographical features. The drives encompass Coalseam Conservation Park and the fascinating Bindoo Hill, a glacial moraine where ice smoothed rocks dropped as the face of the glacier melted around 225 million years ago. The historical Butterabby Graves, where three Aborigines were hanged and buried for the spearing of a shepherd, is also included in the scenic drives. Each site features a creative rusty steel sculpture with an interpretive panel to explain the main story associated with the location. A number have picnic tables and fire-rings, and all roads can be driven in standard 2WD vehicles (with care on unsealed sections). Both trails are well sign posted so there is no risk of losing your way.
