|Route outline (key)|
The B3289 is part of the most direct route from Truro to St Mawes.
The road starts out at a T Junction with the A3078 in St Just in Roseland on the Roseland Peninsula. It goes in a northerly direction on a S2 road passing no places of any size. After a couple of miles it turns sharply left to head west to the River Fal. It follows the river inland for a short distance before reaching the slipway to the King Harry Ferry.
The B3289 reappears on the far side of the River Fal at Trelissick and the road zigzags up away from the river. It then continues west past the National Trust's Trelissick Garden and then reaches a crossroads. Straight on is the strangely named settlement of Come-to-Good - but the B3289 has to TOTSO right here. It heads north once more for over a mile until it reaches a roundabout on the A39 at another strangely named settlement, Playing Place. The road ends here.
