If coming from the west approach along the A316 (Chertsey Road).   If using the M25 leave at Junction 12 and follow the M3 towards London until it becomes the A316.   After crossing Twickenham Bridge pass the sports fields on the left and take the first left entry - signposted  “Pools on the Park” and Royal Mid-Surrey Golf Club - and then almost immediately fork right through the Golf Club gate  
The car park is on the right just before the Club House.   Allow plenty of time as the A316 is busy in the mornings, but the traffic keeps moving. 

If coming on the North Circular join the South Circular (A205) at Chiswick and after crossing Kew Bridge turn right at the lights and follow the road past Kew Gardens (A307) until reaching the large roundabout at Richmond:* exit west on the A316 and after 100 yards enter the right filter lane and take the second gap - also signposted as above - and cross the other carriageway into the entry to the Baths and the Golf Club.

If coming from London take the A4 over the Hammersmith Flyover, towards the Hogarth Roundabout at Chiswick. From the roundabout take 1st exit signposted the A316 to Richmond Circus roundabout, then proceed as above at *. Anyone approaching by another route should come to the Richmond roundabout and exit west on the A316 in the same way.
