Plenty of good walking and exploring around Bath, and loads of good pubs and eateries; more eateries than you could reasonably expect to sample in a weekend. The Raven’s good in the center, and if you go for a wander over to Victoria Park, look for St James’s Wine Vaults just off Julian Road in St James’s Street. Lovely cosy little pub, proper local with a great atmosphere and good beer. I have a good friend lives in Bath, and it’s our ‘local’ when I go down to see her. She only lives about ten minutes away, so it is local.
Lovely walks through Sidney Gardens up to the Canal, and you can then walk back down to Widdcombe, and along the river past the Rec to Pulteney Weir. Bath’s blessed by the fact it’s a very small city, so quite easy to cover most of it easily in a weekend.
