Isla Gorge National Park, Nature reserve in Banana Shire, Queensland, Australia.

Isla Gorge National Park is a nature reserve covering about 78.5 square kilometers in Banana Shire with elevated cliffs, deep valleys, and diverse woodland zones throughout. The landscape displays varied terrain and vegetation patterns that create different habitats across the protected area.

Isla Gorge National Park was gazetted in 1964 on the traditional lands of the Kongabulla Clan of Iman country and Wulli Wulli country. In 1990 its north-western section was expanded to take in a hand-laid stone road built in the early 1860s, only about 15 years after European settlement of the district began. That road once carried wool from Roma to the port of Rockhampton.

The park lies on the traditional lands of the Kongabulla Clan of Iman country, the carpet snake people, and on Wulli Wulli country. The two groups are the recognised Aboriginal peoples of this sandstone country around the gorge.

The park is accessible via Leichhardt Highway south of Theodore and provides camping areas and toilet facilities for visitors. Plan visits during the dry season for the most comfortable conditions when exploring the terrain.

The sandstone formations in the gorge display natural patterns that shift in color throughout the day depending on sunlight. These geological features have been shaped over millions of years by erosion that continues to alter the landscape gradually.
