A suggestion to see most of Bath beauty in one day walking… A LOT! 9:00-10:30 Let’s start with a walk in the Botanical Garden and Royal Victoria Park 10:30-11:30 Visit The royal Crescent, The Circus and move to the center dow Milsom street (have a look to the Gallery) where you can visit the Abby and see the Roman Bath building 11:30-13:30 take the bus/taxy/walk to Prior Park. A nice idea is to walk down the park and exiting from the old Hut exit. From there you can visit the rainbow farm and have a nice view of the city. 13:30-15:00 Finally have some food in one of the many Good Pub of Bath, or a Snack around. 15:00-18:00 Visit whatever you want in the city center (The Clock Tower (check the closing time), The Roman Bath, The Hopburn Museum) . From the Sidney Gardens, you can have a 40minutes walk along the beautiful Canal Sunset: If you can still walk go to alexandra park and enjoy the golden hour view of the park.
Ok, this is pretty intensive, but basically you can see everything! Soon a more “normal” doable visit.
