Narrative:
Icing forecast but all airports along route forecasting VFR. The first half of the trip was without incident but then at 8000 ft entered clouds. Initially no ice but after 20-30 minutes picked up slight rime ice. Initially descended but ice was worse at 6000 ft. Cleared to 10;000 ft and broke free of clouds at 9000 ft. Later started descent for approach. Held at 6000 ft as this was minimum vectoring altitude. Started picking up significant ice and ATC could not get me lower due to MVA. I knew there were VFR ceilings beneath me so I [advised ATC of conditions]. Descended to 5000 ft and remained clear of clouds to the field and an uneventful landing. The presence of VFR conditions kept me from filing an alternate; and the terrain following GPS assured clearance from mountains. In the future if icing is forecast I will likely arrange to fly to a different airfield to remain clear of the possibility of icing.
