Last summer, my cousins and I planned a camping trip to Mt Kosciuszko, as we do every few summers. Lightning storms were forecasted and the trip had to be relocated as one of our friends had a metal plate in his arm. We decided to change our camping location to Wolgan Valley, closer to home and near the Glow Worm Tunnel Walk. Twenty four hours before the trip, bushfires erupted in that area of the Blue Mountains. Running out of options and time, texting alternative tracks close to midnight, we settled on the Berowra to Cowan section of the Great North Walk, the section frequented by Seven Summit enthusiasts and ultra marathon runners.
