Hi trickos, I did the Tabletop walk in July last year.
It's a great walk, savannah, woodland, waterfalls. Between Wangi and Walkers the track follows along the top edge of the escarpment, magnificent views, a few road-innaccessible waterfalls tumble 100m over the edge.
I did the walk in two days but would recommend taking a little more time (I was taken a little ill.) As always in the Top End walking in the morning and resting in the arvo is the best plan, it is very hot in the arvos out in the sun and away from water. About half of the track is through unshaded savannah.
You can access the track from any of the Link Walks - Florence Falls, Greenant Creek, Wangi Falls or Walker Creek. Many of the waterfalls on the link walks are crowded with people, but you'll appreciate the refreshing swim. Wangi is by far the biggest falls and tourist attraction, a fancy new visitor centre is under construction and they sell icecreams.
There are two very special campsites - one is marked on the map but apparently unnamed, 3km east of the Greenant Creek link walk. It is not accessible by vehicle, see photo below, shady camping, a single metal table. There is a toilet some distance back from the water, follow the placed-rock trail.

The second is Walker Creek. This one is popular, there are eight secluded campsites. It is at the carpark end of the link walk, but is a 750m to 1.5km walk from the carpark. The campsites are spread out over the 750m or so of creek. They each have their own rock pool, bit of creek and/or waterfall. Some are very private, some a bit closer and more visible to the main track. You cannot prebook, simply turn up early one morning (or on a quiet day) and write your name on the chalkboard just beyond the carpark (when someone has vacated their campsite and rubbed off their name). Walker Creek is the longest drive into the park from the Stuart Highway. If you walk in from the Tabletop Track the campsites start when you reach the toilet, to the left are sites 6 to 8, to the right the carpark and sites 1 to 5.
Here is a list of the sites, I didn't see a couple cos people were there:
Site 1. short driveway so little privacy, big pool, big falls
Site 2. no privacy
Site 3.
Site 4.
Site 5. no privacy, visible from track
Site 6. also day use area. big plunge pool. mulitple falls. toilet nearby.
Site 7. best campsite ever (of the ones I saw), huge plunge pool
Site 8. remote, small, creek access
I would recommend carrying the topo map stipulated by Parks & Wildlife. Like many Top End tracks the track can vary from being easy to follow to difficult, fire scarring will make the track difficult to follow. I got a little lost in a creek crossing between Wangi and the next campsite clockwise. I would usually have a GPS file to offer, but had lost my GPS unit just before this hike.
Another good rockhole for swimming is Buley Rockhole (or Buleys), it is not marked on the Tabletop map, it is just south of Florence Falls.
