Easter Sunday 2014: We summitted Boyds Butte at west end (elevation 520 m) and sat on rock to admire view, much surprised to find large red bellied black snake asleep on next rock. Plan was "From the public car park at Cougal Cascades picnic area at the end of Currumbin Creek Rd we enter the Cougal Nat Park and walk an easy 1.5 k along the tarmac path to the Old Saw Mill. We proceed W along the creek bank for 200 M then cross the creek and at the sharp bend we will take the ridge line route - this is marked with red fluorescent tape on saplings as it climbs away from the creek and is used by the geocaching gang. Its not much in terms of pure distance ( approx another 3 k each way - but we can expect some rought terrain I'm sure ! ) The ascent should take approx 2 hours - less to return. It should be almost impossible to get lost as Currumbin Creek will always be below us on our left". Actually it is a strenuous 2.5 hours climb, even in perfect weather, across some v rough terrain - route is quite well marked with red fluorescent tape and we added more where necessary. My wife nearly got wiped out by a mini rock fall, steep sections are quite hazardous !
