Overcast and drizzle at times today. We did some shopping at Margaret River before we drove to Mammoth Cave. Here they gave you MP3 players and headphones and you did your own tour of the cave. Compared to the other ones, this was much easier to do and was a living cave like Lake Cave. You entered one end of the cave and walked along the length of the cave which had water in the bottom and a fossil jaw bone still embedded in the rock. Some very large stalactites , columns, etc on display and the beauty was you could wander along at your own pace and this allowed for better appreciation. The walk out was through the collapsed opening at the other end and quite a lot of steps. We found ourselves on the other side of the bitumen main road and had to walk about 200 m back to the starting point. All and all a cave well worth a visit. All 4 caves we have done in the South-West have been different and all worth a visit. We then drove south on the Cave Road to a spot where there is a valley of giant Karri trees and a spot to pull over and take in the view at a viewing platform. The drizzle made the place even more majestic and no matter how much video/photos we took, they could not do the area justice. We fueled up at Karridale, a small township and the cheapest fuel we could fine before travelling on towards Pemberton. We had some lunch in a nice picnic area on the road before setting off again. The trees were enormous and this made the drive very scenic up and around the hills. We stopped off at Beedelup NP to have a look at the water falls. Very pretty place but the suspension bridge was a bit wild. A short drive into Pemberton to find the Information Centre and the Discovery Centre to pay for some tours for tomorrow and to find the caravan park (set amongst the trees ). It was cold and wet, so hopefully better tomorrow.
