Getting there & away
Most hotels (including Whitfield Hall and Wildflower Lodge) in the Blue Mountains offer 4WD transfers to Penlyne Castle from Mavis Bank (from US$20 per vehicle) or Kingston (from US$40). The Wildflower and Whitfield transfers are untrustworthy in late evening, when drivers often don’t show up (or refuse to continue), stranding people in Mavis Bank. Be sure to arrange a transfer for no later than mid afternoon.
If driving, continue through Mavis Bank to Mahogany Vale and cross the Yallahs River.
Penlyne Castle is reached via a 5km dirt road that ascends precipitously from Hagley Gap. Only 4WD vehicles with low-gear option can make the journey, which is dauntingly narrow and rugged.
