The Alder Ring is a natural campsite along the Witels River in South Africa's Western Cape. It sits beside the river and takes its name from the white alder trees — "witels" in Afrikaans — that grow in the area.

The site features flat rocks and steps leading down to a pool, making it a naturally inviting resting place.

The Alder Ring is reached on the second day of the multi-day Witels traverse, a demanding route that involves extensive boulder-hopping and numerous swims through narrow slot canyons. Hikers float their packs through passages that are otherwise impassable.

The site is considered one of the more desirable overnight spots on the route, though it is not always reached depending on a group's itinerary.
