Some nice views of the lake, and decent curves. Other than that this is nothing special compared to many other roads. Road is in so-so condition, with low speed limits many places.
ipetterRural surroundings, gain a little altitude for views of Tyrifjorden, otherwise it's just sprint-corner-sprint-corner-etc. ... ;o)
sjamondkA very little travelled route. It is practically not used,
as even the locals rarely travel between the two towns,
but rather towards Drammen or Oslo (and other routes are shorter).
In former days this was part of the Round the Tyri Fjord rally.
Today it is mostly good for a sight-seeing tour of the South of the Fjord
(which is really a lake). Can and should be combined with a round-the-lake
itinerary.
