Donnelly's Castle

Donnelly’s Castle is a natural rock formation located in The Summit, featuring massive granite boulders that create a labyrinth of caves and narrow crevices. Visitors can explore the interior passages or climb to the top of the rocks for views across the surrounding countryside. This site has historical significance as a reported hideout for the bushranger Captain Thunderbolt, who used the rugged terrain to evade authorities during the nineteenth century. The area is managed as a public reserve, providing a rugged landscape for outdoor exploration without the need for intensive hiking gear. Access to the site is via a short walk from the parking area, making it a convenient stop for those travelling through the Granite Belt. Nearby, Mount Marley offers additional scenic perspectives of the Darling Downs landscape. The Summit remains a key destination for travellers looking to experience the unique geological features of the Stanthorpe district. Facilities at the reserve include basic picnic tables for self-contained breaks within the natural environment. These granite outcrops provide a distinct contrast to the agricultural surroundings typical of the region.
