Between Carnarvon ON (just north of Minden) and Haliburton ON is hwy #118. 11.5 kms west of Haliburton, or 12.6 kms east of Carnorvan, on the north side of hwy #118 is Kennisis Lake Rd.
Kennisis Lake Road winds for 28 kms through gorgeous Ontario cottage country. I didn't give it a 5-star score for scenery because it's no Cabot Trail or Icefields Parkway. But it's very, very nice. I rode this in the Fall, at the height of the leaves changing colour. Absolutely gorgeous.
The first couple of kms of the road are nothing to write home about. Then the road curves to the right and gets smaller. And the fun begins. The road continues to get twistier and long sweeping curves as you get closer to the end. Totally paved till the last couple of kms. After that the road surface is very hard pack gravel, almost like pavement.
Strictly a cottage road, with no amenities. And no gas.
