The Tree Top Walk is amazing - the views are breathtaking. However, you only get to spend an hour there, despite the fact you leave Perth at 8am and you don't get back until 11pm! It's was so rushed! I know it's a long way but I felt that this trip spent far too long on the coach. If I were to go again, I'd perhaps get a hotel nearby and spend several days exploring Southern Western Australia and all it has to offer in full. It's too far away for a realistic day-trip from Perth.
Really enjoyed this trip. The stops are well planned out so you're not spending too much time on a coach. There's the animal park in the morning you get the opportunity to stroke koalas, kangaroos and wombats - not to be missed, then a stop for lunch, then onto the Pinnacles for great photos and later in the afternoon, onto sand-boarding and the 4WD! A very enjoyable day out.
