Campsite 420 is a paddle-in backcountry site on Buzzard Lake within Kawartha Highlands Provincial Park in Ontario. It accommodates up to nine people and is reached by canoe, with a portage required to access the lake.

The site is equipped with a picnic table, four tent pads, a fire ring with grill, and a privy. Its east-facing orientation catches the morning sun while providing afternoon shade.

A small island roughly 100 feet offshore makes for a popular swimming destination.

Note that sites 420–424 are within view of one or more private cottages, which are grandfathered within the park boundary, so the setting is less secluded than other spots on the lake. Reservations are made through Ontario Parks.
