The vast Border Ranges National Park covers 317 sq km on the NSW side of the McPherson Range, which runs along the NSW–Queensland border. It's part of the Gondwana Rainforests World Heritage Area and it's estimated that representatives of a quarter of all bird species in Australia can be found here.
The eastern section of the park can be explored on the 64km Tweed Range Scenic Drive (gravel, and usable in dry weather), which loops through the park from Lillian Rock (midway between Uki and Kyogle) to Wiangaree (north of Kyogle on Summerland Way). The signposting on access roads isn’t good (when in doubt take roads signposted to the national park), but it’s well worth the effort.
The road runs through mountain rainforest, with steep hills and lookouts over the Tweed Valley to Wollumbin/Mt Warning and the coast. The 10-minute walk out to the Pinnacle Lookout is a highlight and one of the best places to see the silhouette of Wollumbin against a rising sun. At Antarctic Beech picnic area there is a forest of 2000-year-old beech trees. From here, a walking track (about 5km) leads down to lush rainforest, swimming holes and a picnic area at Brindle Creek. If you do take a dip, be sure you're not wearing sunscreen or insect repellant as the chemicals are dangerous for the local frog population.
To access the Tweed Range Scenic Drive from Murwillumbah, follow the Kyogle Rd west to Lillian Rock then turn right at Williams Rd and follow the signs. It takes around two hours. If travelling from Lismore, the drive takes around 1¼ hours.
