Another old favourite:
Train: the location is about 10 minutes walk from the station (main entrance on the West side, platform 1), slightly longer on the way back (uphill!). From Leeds, trains are at least half-hourly until around 20:30, hourly after that. The last train back is 23:18. From York, trains are hourly at about 11 mins past the hour, last train back is 23:18. In each case, journey time is about 35 min. Please check times before travelling.
Bus: The location is also about 10 minutes from the bus station where there are services to and from the local areas; in addition, there is the frequent 36 Leeds and Ripon bus (drops to hourly after 9-ish in the evening).
Car: Parking in Harrogate can sometimes take a bit of searching. You may find a space on the nearby streets such as Valley Drive or Montpellier Gardens, or if you're really lucky, directly outside the pub. For those who simply can't get enough smartphone apps, there is "AppyParking" which shows any free on-street spaces.
Foot: For those who left their GPS at home: shame on you! From the Railway Station, head a short way N to the pedestrianised Cambridge St (Cafe Nero on corner). From the Bus Station, head S to the same. Walk along Cambridge St and, at the end, pass the War Memorial and head down Montpellier Parade to the left of Betty's. At the roundabout go to the left of the Crown Hotel on Royal Parade and your destination is there on the left.
Location: The listing coordinates are for the Old Bell. Food available. Depending on likely attendance, I may or may not book a spot.
Dogs: Allowed!
