Car Parking
In addition to the car parks shown on the Winter Gardens website there is a large car park owned by the Royal Hotel next to the Winter Gardens. Entrance is to the left of the Winter Gardens off of Royal Parade on the seafront. This car park is cheaper than the others although the Sovereign Centre car park is under cover.
Directions if you are northbound on the M5
Come off at Junction 22 and follow the signs to Weston-super-Mare, this is much easier if you are travelling up from the south. You will not have to negotiate all the roundabouts, junctions and Town Centre from the Junction 21 turn off where backlogs are common.
