Checked out the Mt Joyce track at the newly opened recreation park at Wyaralong Dam (just outside Beaudesert). Did just under 15k roundtrip from the dam wall carpark to the top of Mt Joyce then down the Ridgeline (both rated advanced) track to the Mt Joyce base camp, then back on the easy rated track to the carpark. Several portions of the tracks are shared with bike riders but the I had no issues and the tracks are wide enough for all to use. Vertical climb is about the 350m mark but not too difficult. A couple of massively thorny shrubs in the wrong place and need to be avoided as handholds in those scrambling bits. The Ridgeline track back down to water level is pretty loose in parts and it will be interesting to see just how much erosion happens once the path is well worn and the rain does its work. Pretty open scrub/dry forest and interesting 360 views from the top of Mt Joyce. I see potential for a larger circuit to include Flinders Peak, for example. Saw Prettyface wallabies and schools of carp (in the water) and a fair smattering of birdlife. A good day out in all.
When the recreation park is completed, there will be about a 30k walk between the East and West trailheads; one path will be up and over Mt Joyce and will require a bit of an effort. The recreation park already has a really good mountain bike park and several canoe "tracks". The only through walk camp site I am aware of so far, is about 7.5k from the car park and is not really convinent for anyone wanting to do the 30k walk in two relatively easy stages. But this is all early days. Lots more is planned for the facility and I'm looking forward to doing the canoe bit at least. Interested people can get a map of the park here.http://www.mtjoyceescape.com.au/walking-trails.html
Camping at the dam is free at the moment and site numbers are limited. Caravans and camper trailers are banned and stink boats are not permitted on the dam. I suspect this place is going to be VERY popular in the future and right now might be a good time to check it out.
Phillip, if you read this, no hammock potential but I suspect the organisers would positively respond to a request for the installation of suitable facilities at the camp grounds (can you think of a more minimal impact over nighting method?). The organisers seem to be very advanced in their thinking and seem very keen to respond to public wants and needs.
