Through the gate a sign gives the distance to Brandy Flat as 5km, but the 4km to Booths Hill is just an indication as there is no defined track up Booths Hill.

The road goes downhill through dry forest - broadleaf peppermint, candlebark, silver wattle, acacia rubida and a small Hovea sp with purple flowers. This gradually changes as you near Dry creek to snow gum, black sallee, sweetbriar and hempbush (Gynatrix pulchella) along the creek.

Despite its name the creek is rarely dry and often means wet feet. It is possible to avoid the steep climb of 160m by contouring on a bearing of 20 degrees following animal tracks; assuming that you follow the road, the understorey changes to include Leucopogon, shaggy pea, Pultenaea, Astroloma, box-leaf wattle, and a view of Sentry Box and Gudgenby mountains.

The crunch of gravel underfoot indicates a change of basal rock to granite as you approach the hut, which is set on the edge of apple box and blackwood just starting to flower, with a view into the Naas valley. The hut was originally planned as a shelter for Booroomba Rocks, but public opposition saw it trans-ferred here and rebuilt as a hut in 1979 in the newly declared Gudgenby Nature reserve. It has a steel deck roof, concrete slab and pine walls, quite different from the succession of shepherds huts that have been built there since last century, the remains of which can be discerned nearby.

There is a water tank which someone has put a hole in, fortunately halfway up, a fireplace and toilet. Brandy flat used to be on the weekly mail run to Gudgenby. The mail was carried by horse from the Naas up Gudgenby creek, along bridle trails.

From Brandy Flat there is a road down Gudgenby Creek to Caloola Farm, bulldozed during the 1983 fires, and consequently not shown on the CMA map published in 1981.

A more interesting way out is to continue through to Glendale if you've left a car there. The road can be seen to the north ascending through heavily grazed land.

The last part of this walk could flippantly be described as 'Roos, Rangers and Rabbits', but is in fact the most scenic of the day. After turning south west downhill and crossing Reedy creek, watch for the marker which directs you to the right up hill. Follow the cairns around the spur and down into the valley along this welcome change from the fire trails. Shortly after crossing another shady creek you are at the locked gate and car park of the Glendale Depot.
