If you are driving to Hove, you can take the A27 from Brighton or Shoreham-by-Sea. Alternatively, you can take the A259 along the coast. From London, take the M23 southbound, then join the A27 towards Brighton and follow signs for Hove.
If you prefer to take the train, Hove has its own train station with direct services from London, Portsmouth, Southampton, and other cities in the South of England. From Brighton, it's just a 5-minute train journey to Hove.
If you're coming from other local landmarks, you can take the number 7 bus from Brighton Pier, which stops in Hove. Alternatively, you can take the number 700 or 702 bus from Worthing, which also stops in Hove.
If you are visiting other cities or towns near Hove, I suggest taking a train to Brighton and then board a bus or take a taxi to Hove. Alternatively, you can rent a car and drive to Hove from nearby cities and towns.
