No, we didn't

9.30 - 1700 daily

I believe it is 18

It is £3.00 to park but entry is free with a voluntary donation

Je ne saurais donner de chiffre ...mais il s'agit d'un ascenseur grillagé qui descend/remonte tout en douceur. Je n'ai malheureusement pas de photo, car nous devons laisser tout appareil électronique en consigne à l'entrée.

Yes they do

Honestly don’t know, suggest you ring the Museum.

I saw lots of canine visitors - and apart from not letting them down into the mine, I'm certain they would be welcomed.

I'd estimate about 30 mins (16-17 miles) from Newport by car. Buses available as follows: The number 30 bus runs from Cwmbran Bus Station to Lion Street, Blaenafon daily Monday to Saturday, including Good Friday but excluding other Bank Holidays. Bus times from Cwmbran start at 7.40am and then hourly at 40 minutes past the hour. The number 31 bus runs from Lion Street to Big Pit daily Monday to Saturday, including Good Friday but excluding other Bank Holidays. Bus times from Lion Street start at 8.40am and then every 2 hours at .40 minutes past the hour. Return bus from Big Pit to Lion Street from 10.15am and thereafter every 2 hours at .15 minutes past the hour and from Lion Street to Cwmbran hourly at .40 minutes past the hour until 4.40pm. Hope that helps!.

Yes there are. You would still be able to visit parts of the site but there were steps up to the pit head baths and where there are ramps they can be very steep. From their accessibility guide it sounds like they have wheelchairs you can borrow and it is possible to get underground with one but the ground is uneven so I expect it would be bumpy. I'm sorry it wont let me link to their accessibility guide - but you could phone them or search access on their website.
