Two roadside pull-offs that can fit a couple of vehicles each. A really good scope is usually needed to see from the further pull-out though.
The KVR crosses the Princeton-Summerland Road just before the lakes (when approached from Princeton) and can be used to bird the east side of the lake.
Not a lot of parking available where the map pin is placed, but the KVR can be accessed throughout the town so you can park and walk or bike from just about anywhere.
The pavement ends about half a kilometre after the tunnel (heading west) but the gravel trail continues well beyond that.
