Bristol - in no particular order, and some are combinations on a theme
1 Aerospace Museum. out in the suburbs this superb museum does justice to Bristol's aerospace traditions and amongst a lot else has a Concord(e)
2 Bristol Cathedral Roof and tower Tour which they run occasionally. A fairly ordinary cathedral compared to many but the roof tour is a bit special. St Mary Redcliffe church is at least as nice as the Cathedral proper with Queen Elizabeth I calling it the loveliest in England. And not to forget brutalist masterpiece Clifton (catholic) cathedral. All three have gigs on fairly regularly too.
3 Clifton Suspension bridge. Well worth trying to get a tour of the underground caverns in the South end but worth simply seeing
4 Also by Brunel, his ship the SS Great Britain. A walk round the harbour is a fine thing in its own right too, the harbour in and of itself is one Bristol's most interesting sights.
5 Pubs: Bristol is very much blessed with a huge choice of lovely pubs. There are more too notch pubs within a 5 minutes walk from my house as there are in the whole of Cardiff which is mostly chains sadly. Some examples: Bag o Nails (aka cat pub), various busy town pubs in King Street, a few of which are very old, and also The Duke, a jazz pub. The Coronation and the Fringe is Clifton Village, Severn Stars conveniently next door to the Fleece, ab excellent music venue. The severn stars was a meeting place for the founders of the anti slavery movement, which is very much to be proud of.
6 Music Venues, recently done up The Beacon (formerly Colston Hall), fantastic acoustics in the auditorium and hosts proper world class orchestras and rock gigs. Also St Georges, a smaller venue with equally good sound oarticularly for "early music". The Fleece already mentioned has cover bands and some bigger names in their later years
7 The harbourside. Like many formerly maritime cities, the harbourside is now a pleasant public space even if the bars and restaurants are mostly chains, it's still nice to wander round
Now all that said, despite the great appeal of Bristol as a place to live, not least because you can live actually in the city and have everthing within an easy walk, it's not really somewhere you'd go as a tourist, unless there was agig or other event on say.
Well, Bristol is my adoptive hometown now so I'll add to the list with a few odd bits 'n' bobs tourists often miss:
1. Avon Gorge viewpoint; w3w= owners.work.fluid. If you can put up with traffic noise, walk down to the viewpoint for that classic view of the gorge, suspension bridge etc. Good views rom south side of river, M2 bus service stop just before the park & ride. Walk over bridge & turn right, its a few minutes walk, go under the flyover.
2. Afterwards, take a peek at Whitemead House off Duckmoor Road: w3w= inform.vote.copies. Why a block of flats?....probably the most famous in the UK, it was used as Nelson Mandela House in Only Fools & Horses. Check out Penn St in Broadmead, particularly the corner with the Sainsburys on it. I think this was where the 3 wheel van broke down with its occupants dressed as Batman & Robin. Serious OFAH fans should take a look at The Granary, in Welsh Back. It was the exterior location of a certain wine bar in which Del had a famous pratfall......
2. Ashton Court , a park on the edge of Bristol, nice walks, great views, mountain biking too. The lower part hosts the famous Balloon Fiesta.
3. Cabot Tower, Brandon Hill. Walk up Park Street...the famous bloke-hanging-out-of-window Banksy is at the bottom: w3w=happen.next.turns, carry on up and turn left into Great George Street and walk up to the top of the hill (steep!). Nice views plus if you don't suffer vertigo or mind a bit of bird poo, you can climb up the tower - spiral staircase inside.
4. The floating harbour. You can get a boat taxi ride from behind Temple Meads station to the SS Great Britain. Nice way to see the city.
5. Walk on the Clifton Downs. If you tire of the suspension bridge, here are good views of the gorge from here.
6. The Bristol Railway path. Hire an ebike and ride out to Warmley. You pass through the Staple Hill tunnel, pass Mangotsfield station which inspired Arnold Ridley to write The Ghost Train...who's Arnold?...Private Godfrey in Dads Army. Stop for a drink at the Warlmey cafe, nice Marshfield ice cream and you can pretend to be a timelord, the loo is the Tardis (seriously).
