I visited Coolah Tops for the first time in September, 2014. What a stunning spot. To reach the park, you drive about 30 km from the town of Coolah through rolling cattle grazing country on mainly unsealed roads, passing into eucalypt forest at the NP entrance. After a further 10-15 minutes (and a left hand turn) you’ll arrive at Bundella Lookout. A short walk takes you to Pinnacle Lookout with its jaw-dropping views over the Liverpool Ranges, Mt Kaputar and the Nandewar Range. There are apparently equally beautiful views from the other end of the plateau, though the road was closed to two-wheel drive traffic when I was there.
You are guaranteed wildlife sightings along the 9km hiking circuit linking Bundella Track and Racecourse Track. I saw a wombat, innumerable wallabies, kangaroos and birds, including five wedge tailed eagles circling in the sky, as well as two that launched from ground level, right in front of me as I was walking along the track. I’d never been that close to one before.
Other points of interest include a sweet little 1km walk through a stand of giant Grass Trees between Bundella Lookout and the turnoff, as well as a waterfall to your right, not far from the NP entrance. There is a fairly steep but short climb down to the viewing platform for the waterfall. Unfortunately, there was not enough water flowing when I was there to get the full effect, but it would be lovely after a rainy season.
A great place to visit if you want to see some wildlife, take in the view, or just enjoy some quietude in the bush.
