Your have four options
Taxi, most expensive but most likely to get you there
Bus, cheapest but finding out the times and where the bus goes from may be difficult. (First Group timetables are available on line if you do a bit of research)
Train to Swanwick and then walk (25 minutes walk from Swanwick station, instructions are in a much earlier posting in this thread)
