Kwinana Fwy south to Russell Road exit (next exit after Armadale Road exit), then west on Russell Road for 3 kms to reach an off-road unsealed parking area on the right at the entrance gate to the Thomsons Lake Nature Reserve. The reserve is protected on all sides by a 2m high vermin fence .
|Escape route/s :||
This walk is not a 'serious' bushwalk but more an easy stroll around Thomsons Lake (also known as Jilbup Lake), with short diversions into the surrounding woodlands, and perhaps a chance to test your GPS navigation skills if you are new to GPS.
The Lake is just one of several in the two chains of lakes and swamps along the Swan Coastal Plain which together form the Beeliar Wetlands. More than 75% of these wetlands have now been filled or drained for urban development. The small Thomsons Lake Nature Reserve covers an area of only 551ha but is one of the few remaining good wetland environments. It is a Class 'A' reserve and is listed as an internationally important conservation reserve for migratory birds. Early summer mornings are a good time for the walk (especially for keen birdspotters) as the Lake attracts more than 10,000 waterbirds in early to mid-summer before it almost dries out each year.
Although the Lake is surrounded by a narrow belt of rushes and grasses, there are also areas of various different vegetation types, including jarrah-banksia woodlands on the surrounding higher ground and a zone of Flooded Gums and Swamp Paperbarks on the lower ground. About 3 kms of the walk passes through the higher, shaded woodland areas and the remainder is close to the lake and exposed.
Aside from the birdlife, there is also a range of other wildlife including the Western Grey kangaroo (which became over-abundant in the past but is currently under control through DEC's reserve management programme), plus echidnas, and several reptile species including tiger snakes which you are unlikely to see, but take care!

Route notes :
The route is entirely on existing tracks. Although GPS is certainly not required to navigate around the lake, you will probably still find it useful in the northern woodland area because i) markers for the 'official' trails through the Reserve have not been well maintained, and ii) the route does not follow any particular single existing 'trail'.
Start north toward the Lake from the Russell Road park entrance ('START') and at waypt '2' turn right to follow a foot-track via '3' through pleasant banksia-dominated woodland. You can make short off-track diversions to the left of the track to obtain views of the Lake through the trees. At 'TRN' the track turns left and downhill, passing through Swamp Paperbarks to reach (at '4') a wider track close to the Lake. Turn right and follow the track around the eastern side of the Lake past Flooded Gums, Melaleucas and rushes for just over 2 kms to reach a T-junction at waypt '9' in the north. (Note: During winter and spring the track often becomes quite waterlogged in places between waypts '6' and '8', so be ready to get your footwear soaked at that time of year!). Turn left at '9' and walk about 200m toward the Lake, past the rushes, to get a closer view of the waterbirds (more than 50 species visit the Lake). You are also likely to see raptors (Swamp Harrier and Little Eagle) circling overhead. Then retrace your steps and continue north on the track past '9'. Turn sharp left at '11' to follow a track gently uphill through mixed banksia forest and past some large old Swamp Paperbarks. On reaching a track intersection at '13' turn right (NW) and follow the foot-track steadily uphill through jarrah-banksia woodland (and occasional large Tuart trees). A few metres before the track meets the Reserve boundary fence, turn left at '14' and follow an old track which runs parallel to the fence (due south) for almost 500m. Veer SE (toward your left) at '15', cross another vehicle track at 'TRK' and follow a foot-track downhill via '15A', '15B' to get back to the track around the lake at '16'. Follow the lakeside track to waypt '20', then turn right (south) to get back to the Start point.
Right click here and then "Save Target/Link As..." if you wish to download the waypoints and GPS 'track' as a GPX file in the standard format recognised by most devices and programs including Garmin and Magellan units and GPS Mapping Software. If you have a problem uploading the data, please feel free to contact me directly at WalkGPS rather than your users' forum!
The waypoints in the alternative listing below are given as UTM coordinates with datum to match the Walk Map. NOTE: If you wish to manually enter these into your GPS unit you must first set your unit to the correct Datum. Caution: An incorrect datum can result in an approximate 200m location error! (This is a very slow, error-prone method compared to using the above downloadable file and is not recommended.)
