You could easily do this walk in a couple of hours, but what’s the rush? There’s not a lot more enticing than a picturesque stroll along the Yarrangobilly River and a dip in Yarrangobilly’s Thermal Pool. 
Starting from Glory Hole carpark, this walk links up with the Thermal Pool walk, making it a popular loop that can be walked in either direction. Head up the Exit Road to the thermal pool carpark, then descend into the valley to the pool and picnic area. Pack your swimsuit to enjoy a relaxing dip in the spring-fed thermal pool, before following the track as it meanders upstream beside the Yarrangobilly River.
Look out for lyrebirds, superb blue wrens, crimson rosellas and king parrots. If you’re lucky, you might even spot a shy platypus in the river. 
The track then climbs up to meet Glory Arch walk. Turn right to return to Glory Hole carpark, or head left to explore the lofty chambers of South Glory Cave on a self-guided tour (you’ll need a ticket from the Visitor Centre).
