       Route profile

73 kms SE of Perth. Along Great Eastern Hwy to The Lakes, then Great Southern Hwy to Mount Observation unsealed access road (Catchment Road) on right, approx. 23 kms after The Lakes and just past Berry Brow Rd on left. 

18 field kms (95% off-track).

MEDIUM   (What does this mean?)

310m (positive elevation change)

PREFERABLE (to help locate subtle turning points and features).

See Google Map for start point on road map.

(Use zoom ladder for detail. Select 'Hybrid' to add satellite imagery.)

Follow the access road to the Mount Observation picnic area  (signposted on Great Southern Hwy) for 1 km from the Highway and park  at the picnic area. (There are public toilets nearby.)

Important access issue (2008):   Walkers need to be aware that this walk area and many others on WalkGPS lie within drinking water catchment areas.  In 2007 DoW in effect recommended a prohibition of all traditional off-track bushwalking activities across the entire Perth region catchment areas covering 4500 sq km, far beyond the limits of  existing or proposed Reservoir Protection Zones (see map). By March 2008, in the face of growing community outrage, the DoW has reconsidered its published position, advising that it would now be allowing walkers ‘free-to-roam’ access to the forested water catchment areas outside of the RPZs. The community, including visitors to WalkGPS, need to remain vigilant to ensure that commonsense continues to prevail over regulatory zealotry.  See also Home page: 'Access' and Related access issues on WalkGPS, and link below to "Mundaring Weir Catchment Area Drinking Water Source Protection Plan".

Escape route/s :

To Catchment Road (dirt road) in NE (then NW  along Catchment Rd to Start point at picnic area and to Great Southern Hwy, or SE to Helena Rd), or to Manna Flat Rd and/or Helena Rd (dirt road) in south. Pony Rd (dirt road) crosses walk area from Manna Flat Rd in SW to Catchment Rd in east.

Main features

/Highlights:

This walk is within the new Wandoo National Park. It is very pleasant, easy walking through picturesque, open wandoo woodlands (but due to the distance is rated "Medium" in difficulty).  For a shorter walk in similar open woodlands see Christmas Tree Well Walk).  Meney & Brown, 1985, have previously noted of these woodlands:  "..the character and form of the widely spaced virgin wandoo creates a most unique bush atmosphere which is a delight to any bushwalker". 

The route is mainly over reasonably gentle terrain, with a few modest slopes. There are  views around the flanks of Mount Observation and Pony Hill and from a granite outcrop at the westernmost point on the route.

Note: DoW's recommended protection strategy in Report # 69 intended to prohibit recreational off-track bushwalking opportunities within the entire 1470 sq km catchment area, far beyond the proposed 60 sq km Reservoir  Protection Zone, and including this walk area which is more than 30 kms ENE of the reservoir. 

Head south and gently downhill on the picnic area road (with views to the SW through the wandoo trees). Reach an eastward bend in the road after only about 100m (at waypoint '2')  Then continue approx. SSE, off-track, and  initially more  steeply downhill to cross a small gully and climb gently across partly rocky ground (to '3').  Continue across fairly flat terrain to '4'.  Then veer approx. ESE to initially descend to cross another small gully. Then climb gently for almost 1 km, partly across low to medium heath and very open woodland, to reach the summit area of Mount Observation (at '5').  Veer almost south and reach a low granite outcrop (at 'SLAB') on the south flank of Mt. Observation. Veer SSE and steadily downhill initially through open woodland and then across heathland and a  gentle valley floor to cross Pony Road (dirt road) after about 1 km. After '6', veer south to reach '7', then SE, gaining  a view SW to the western flank of Pony Hill, before descending quickly to cross a stream course and a nearby road (at '8'). Continue SE and climb gently through a mixture of low to medium heath, some dryandra shrubland,  and woodland.  At  '9' veer south again and follow the east side of a small gully on the north flank of Pony Hill. (In places the heath or shrubland thickens, but animal tracks provide easy ways through.) At '10', near the top of the gully, veer approx. SE once more to cross the eastern ridge of Pony Hill and soon  descend to a granite outcrop ('RK') on the other side, with a view due south to Mount Talbot about 3 kms away. Veer approx. west, to reach the wooded summit of Pony Hill (at about '11').  Then head NW to soon reach a long SW-sloping granite outcrop partly surrounded by sheoaks. Follow the outcrop NW to another outcrop (at  'RK2') from where there is a good view SW across the small (120 ha) isolated Quinkitchmunging freehold pastoral property toward the eastern flank of Helena Hill. Continue NW back into woodland (at '12') along the western ridge of Pony Hill. Then veer west and stick to the slope at the foot of the laterite breakaway (via '14' and '1-2WAY'), avoiding the prickly dryandra thickets on the ridge above the breakaway. This section is close to the halfway point of the walk and a good spot for a lunch break.  Then veer approx. WNW to continue along the northern side of the gently descending ridge,  There is a fleeting view due north to Mount Observation. Pass a small granite tor (at 'RK4').  Continue WNW to soon descend to the valley floor, cross a dirt road  and then a stream course at '15' (Sadly, when it is dry, this stream and the nearby Helena River course are used as an off-road track by trail-bike riders).  Continue WNW and cross a low rocky ridge, through thickets of sheoak, before descending to cross the Helena River course (at '16').  Continue WNW through woodland to re-cross the Helena River after about 1 km. Continue WNW to soon cross Pony Road and reach the foot of a fairly steeply sloping granite outcrop. Find a safe and easy route up the outcrop to reach an upper level (at 'ROCK'), from where there is a good view back to Pony Hill, now 4 kms ESE. Follow the outcrop approx. along slope, then descend gently NE-ward to '17A'.  Then veer approx. ENE and in less than 500m you will meet Pony Hill Road (at '17B').  Follow the dirt road ENE for 1 km (to '18'). Then turn left, off-track, and head due north for more than 1.5 kms, crossing the western slopes of Mount Observation. At '19' veer NW to soon cross a stream gully and then climb gently to reach a small rocky ledge at 'RK5'.  Veer approx. north, passing through a sheoak thicket, to soon reach '3'.  From '3' retrace about 500m of the route (via '2') covered at the start of the walk to get back to the picnic area road and car park.
