A multi-purpose beach anchor provides a sturdy base for at least one of a small, medium or large sized beach umbrella as well as for an optional table and an optional tubular holder for a fishing rod. The rigidity of the anchor is secured by an integral hand operable slide hammer mechanism for driving the spike element into the sand for an optimal distance straight down. This slide hammer is used by sliding up and down over a tubular support member atop the spike, wherein the spike has an integral strike collar. A few short strokes of the weighted slide hammer element drives the spike into the sand or other terrain. A hand screw is then used to lock the hammer weight to the tubular support and the spike rigidly. An umbrella shaft can then be directly slid over the support tube and locked in place.
