The 142 and 144 buses pass the entrance to Basildon Park and House. It's a short walk up a gentle hill to the ticket office (follow the signs to the Car Park).
Please note that when leaving the park, be careful to retrace your steps back to the same entrance you came in through; some of the signs directing to the exit apply to car drivers not bus passengers, and take a very long way round to get to the main A329 road!
Coming from Reading?
There are direct buses from Blagrave Street stops EO/EP (close to the station and the Town Hall) at 11.15 and 13.45 Mondays to Saturdays or at 11.05, 12.55 and 15.10 on Sundays. The return fare is £5 adult, £2.50 children (5-15). Buses back to Pangbourne and Reading leave the entrance on the main A329 road at 12.23, 15.03 Mondays to Saturdays, 17.23 Mondays to Fridays or at 12.15, 14.20 and 16.20 on Sundays.
If those times are not convenient, why not get the train to Goring where there are connecting buses to the Park, leaving Goring station at 09.50, 12.15 and 15.10 Mondays to Saturdays or at 10.05, 12.05 and 14.10 on Sundays. It's just a ten minute journey on the bus from Goring. You can either buy a return from Goring to the Park (adult £4.50, children 5-15 £2.25) or if you buy a single to Reading (adult £5, children 5-15 £2.50) you can come back to Reading on the bus using the same ticket. Just tell the driver that you want to break your journey at the Park so that you don't get charged twice!
You can also do the same in reverse - buses leave the Park at 11.56, 14.26 and 16.56 to Goring station on Mondays to Saturdays, or at 11.32, 13.22, 15.37 and 17.37 on Sundays.
