you can go thru aspen grove (5A) then 97c to kelowna. now i think its quicker thru keremeos (3a) and over to penticton then to kelowna. i give you the first way becuase there is road construction between summerland and peachland but this is the times...PROJECT NO. 21906-0002 - HIGHWAY 97 : OKANAGAN HIGHWAY No.97 BENTLEY ROAD TO OKANAGAN LAKE PARK : Arthon Construction Ltd. - Sand, Gravel, Crushed Rock, Stone, International Shipping, Underground Works, Paving, and General Contracting
i think its about 2 hours i could be wrong. also theres a back road between princeton and summerland then you goto kelowna all dirt tho might save 30 min beauty drive.
hope this helps....
