Experience of Naukluft trail

Hi! We are looking at doing the Naukluft trail in June. We are just a bit concerned about the heights.
Is there anyone out there who can tell us more about the severity of the heights and climbs? Or just your overall experience of the trail. Hope to hear from you guys!

I am scared of heights. Did the hike last July. Just kept my eye on the trail and did not look down where there was a dropoff. This included the bits with chains. Fortunate to have Mountain Club members along.
