Dalwallinu is the first town along the Wildflower Way, a route that stretches north to Geraldton and showcases beautiful outback wildflowers carpeting the countryside. The wildflower season is from July to October, and during this time thousands of nature enthusiasts make the trip along the Way. Every September, Dalwallinu hosts the Wattle Week Festival to celebrate the wildflower season. A street parade, market day and cabaret are some of the festivities.

Dalwallinu has an interesting history. The first graziers in the district were Benedictine monks from New Norcia who shepherded sheep on vast pastoral leases taken up in the nineteenth century. However, European settlers arrived at Dalwallinu in 1907 with the ambition to develop the area into a wheat-growing region.
