It appears there has been a mix-up in your request. Viewpoint Heilam in Lairg, United Kingdom, isn't a beach location but more of a scenic viewpoint in the Scottish Highlands, far removed from coastal beach activities or amenities that come along with beach settings. This picturesque point offers a tranquil setting, dominated by the vastness of the Highland landscape rather than the sandy stretches and aquamarine waters typically associated with beaches. Therefore, attributions such as sand color, beach length, and amenities like lifeguards, bathrooms, or activities like surfing don’t apply here. Instead, Viewpoint Heilam Lairg is characterized by its breathtaking panoramic views across the Highland terrain, offering a different kind of natural beauty that doesn't revolve around the typical beach experience.
