The umbrella pole having an upper member for supporting the canopy and a lower member for self-anchoring the umbrella into a ground surface. The upper member being an elongated tubular sleeve having a first end communicating with and supporting the umbrella canopy, an axial lumen formed within the elongated tubular sleeve, and a second end for receiving a pole standard into the axial lumen. The lower member being a pole standard having a length, a first end formed for insertion into the axial lumen of the elongated tubular sleeve, and a second end formed for anchoring into the ground surface. A hammer is fixed to the elongated tubular sleeve, the hammer included for transmitting an axial force applied to the elongated tubular sleeve onto an anvil. The anvil fixed to the pole standard for receiving the axial force from the hammer and transmitting it to the pole standard to anchor the pole standard into the ground surface. An optional tilt mechanism for angling the canopy relative to the umbrella pole is included in the present beach umbrella. Also, an optional handle is provided at the top of the canopy of the umbrella. Additionally, the umbrella pole can be used without the canopy to display a flag indicating the user location on a crowded beach, or in pairs to mount a net such as for volley ball.
