We hiked the mid length trail one afternoon in September before leaving Plett. Its an easy to average walk, just wear good hiking boots and take plenty of water. There are some ups and downs, most notably a very long stretch of sand at the midway point. Make sure you follow the path correctly to avoid having to walk UP this rather than sliding down.
Our only concern, at which point I got VERY wet and genuinely thought I was going to die, was when we were returning to the car. The rocks are very slippery and the ocean was rough. With the tide coming in, we had no option but to press on. In the end, I ended up clinging on to the rocks and being splashed by the water. It was very scary and I wouldn't recommend it for children/young adults or the elderly. There were definitely waves which could have swept us away. I don't know whether this was because we timed it incorrectly (it was 2.30pm and the high tide wasn't until 4.30pm though) or whether because there was some wind at the time. We hadn't had any wind, and there was none predicted, so just be very careful.
