Trephina Gorge Nature Park

This is classic MacDonnell Ranges rockhole country, beautiful and isolated the further upstream you walk. Trephina Gorge Nature Park, in the East MacDonnell Ranges, is noted for its sheer quartzite cliffs and river red gum-lined watercourses. Two gorges dissect the range: Trephina, with its wide views and sandy creekbed, and John Hayes Rockhole with steep, narrow rock walls. Waterholes in this area attract much wildlife, including a diverse range of birdlife.

John Hayes Rockhole is a popular swimming location during warmer months. However during prolonged dry periods oth these waterholes may evaporate, leaving only a sandy creekbed.
