Hi Tom,
If you’re trying to find a suitable place to boulder then it’s a combination of things that lead you in the right direction. Firstly, where you are based/ where you are willing to travel to (England is pretty big!) and what the weather is doing/ has been doing when you want to go.
More specifically, to narrow your search down, you could start looking on the crag database on this site to see what is close to you and then move outwards - you can glean a fair bit just from looking at descriptions/ pictures/ comments as these give you a good impression of a venue. Guidebooks to a particular area will then be more specific, with comments on specific boulders/ crags/ problems. Finally, there is no substitute for local knowledge so going and scoping it yourself/ asking a local is always good.
If you’re interested in getting a guide then Boulder Britain by Niall Grimes is a good place to start as it covers loads of venues in enough depth, does all the things you are asking for - walk-in, topo, landings, shelter etc. If you’re interested in any specific places/ need some guidance with stuff in Gloucestershire then give me a shout and I can photo a few pages for you/ give you some info to get you going.
