The park was nice and quite large. I could not say the same of customer service. At the entrance there was a clear sign that concession would provide a discount however upon querying I was told this was only for seniors. When entering the car park, there was a sign that this was full but instead it was half empty. The park area was nice but we could not walk on the grass as there were animal excrements literally all over the grass. We managed to see one koala and one kangaroo. The atmosphere was peaceful however there was area for improvement.

This is a lovely park - so scenic. There is heaps of space and some great walks.

The staff in the info center are great.

The tour of the Crystal Cave is well worth it ($10) and the guide does a great job.

Make sure you drop into the chocolate shop for some exceptional chocolate.

My family makes a trip there every few months for picnics and I always get amazed at how the place does not change as compared to other parts of Australia, this is one place where having no changes is good.

It still feels like years ago and brings back memories. It is great for picnic with the family and you can get to see koalas.

We go to Yanchep very often and since we only pay $10 per year it is fantastic value for money. We go with our two kids (6 and 4) for picnics and for a short hike around the lake and look at all the animals. The kids especially love the Koalas. It gets a 5 star rating from us.

I went to Yanchep Park in winter. There were only one other family, and it was very quiet and peaceful. There were lots of wild birds, ducks and kangaroos in the park, and the kids had a fun time spotting them and chasing after them....;-)
You can look at the koalas resting and feeding on the trees at the koala sanctuary, where the kids can safely walk along an elevated footpath.... and the koalas are safely kept at a reasonable distance from visitors.
There's the Jewel Cave, with guided tours (at a low price) at scheduled times, you'll need to call in advance to check if the weather permits access to the cave. Its the nearest cave you can visit while in Perth, the other caves are down south about 2 hrs drive away.

Yanchep National Park is an affordable and enjoyable day out. It costs $11 for vehicle entry and your free to spend your day in the park; they have a koala sanctuary, great lakes and parklands for picnics plus kangaroos, ducks, etc roaming around. The Kangaroos come out in droves around dusk it's quite a sight! There are other activities you can do for an extra fee such as going into the caves. There is a kiosk plus a restaurant/hotel in the park.
