Jacob W rated Cape to Cape Track, Margaret River a 5 out of 5
Myself and a mate completed the C2C in 5 nights and 6 days, making use of the provided free campsites to silently give up and sleep as our blisters rubbed raw (didn't help that my shoes weren't broken in properly.)
Utilising the free campsites made for some lengthy and difficult days. Going from Boranup Forest with its (beautiful but painful) ascents and descents, to Hamelin Bays very very long stretch of flat sand, was a pretty rough battle to complete in the same day, although incredibly worth it (in retrospect..)
Each free campsite had plenty of unfiltered rain-water, so we didn't need to worry about dehydration, as long as we had enough purification drops. (Though this could change depending on the season I'm sure). The free campsites also had well looked after drop-toilets and lots of seating areas to have some yarns with fellow hikers.
Despite making for some long days, the free campsite approach to the Cape was a really rewarding and a good way to do it if you're not afraid to punish yourself a bit!
My only advice to anyone (like myself and my mate) who doesn't think too much about what happens after reaching the end, is put some time into planning into how to get back to wherever your car is.
We finished in Cape Leeuwin and realised that we weren't able to make it to Augusta in time for the bus back to Dunsborough, so we ended up hitch-hiking back to Cape Naturaliste, a very lengthy and daunting process as we'd essentially just finished the Cape to Cape and needed to do even MORE walking!?!?! Thankfully we met 5 absolute legends that helped us get to our car before we started to lose hope.
(Massive MASSIVE shout out to Andrew down Duns ways, you're a real G for picking us up during that final stretch. Cut down what would have been the most difficult 3 hours of the whole trip into a 15 minute drive, bossman!!)
TL;DR - The Cape to Cape is an absolutely amazing hike. I'd wholeheartedly recommend it to anyone capable of pushing through some gnarly terrain and with enough sense to break in their shoes properly. Make sure you put some time into thinking about the end game of getting back to your car/location, and enjoy what is one of the best walks I've had the privilege of experiencing in recent years!
