From Helston take the A3083 towards Culdrose and The Lizard. Just past Culdrose, turn left at the mini roundabout onto the B3293 to Goonhilly/St Keverne. At the top of the hill (Mawgan Cross roundabout) take the third exit (do NOT go into Mawgan village) drive past Garras Primary School and just round the corner take the left turn signed to Trelowarren. Drive down the slip road and in, right, through the gates. The drive is approximately 1 mile long to reception. Beware of the speed bumps. When you get to the top of the drive turn left for reception and The Walled Garden Spa and straight on through the Restoration gates for the Restaurant and the Galleries.
Do not follow the sat nav as it usually takes you around to Mawgan.
