Meeting at the end of the Great Western Highway at Lapstone, we inspected the John Whitton monument and the gate house ruins, before heading up the former rail alignment to the impressive sandstone Knapsack Gully Bridge, which was initially a rail bridge and later a road bridge (and now a foot bridge!)

Moving on we visited the zig zag bottom points site, then up the track to the tunnel where Arthur Streeton painted Fires On.

Another old rail alignment led to a lookout for morning tea overlooking Glenbrook Creek and the plains.

After further view points, we walked streets in Glenbrook, crossing the main road, and through more bush to Elizabeth Lookout for lunch.

More railway memorabilia: the Winding House Base for a railway and old telegraph poles used in the construction of the new railway line
Next we visited Marges Lookout (another view point overlooking the plains), 
The view of Penrith lakes from Marge's Lookout. (No these lookouts were not named after Queen Elizabeth and her sister, Princess Margaret, but after the wives of local dignitaries)
Lennox Bridge (sandstone road bridge completed in 1833) before heading back to the zig zag to return down to the cars.

Lilian's mobile suggested we had walked not 15 km but 18.1 km!
Appropriately for Hillview, coffee was at the Chatterbox Cafe at Emu Plains.
