Campsite 500 is the sole campsite on Sparkler Lake, located within Kawartha Highlands Provincial Park in Ontario. It is accessible by canoe via a portage route that passes through Cox Lake, making it a backcountry paddle-in site.

The campsite offers expansive views of the lake in multiple directions.

Sparkler Lake itself has a reputation for moody, atmospheric conditions — fog rolling across the water at dusk gives the area a quiet, ethereal character that draws paddlers looking for a more remote experience.
