In general a person CAN'T be convicted in the UK for anything that they've done while abroad. It can ONLY happen when there's SPECIFIC provision in the relevant UK legislation allowing for the prosecution of offences committed outside of the UK. (For example some, but not all, offences covered under the Sexual Offences Act 2003 can be prosecuted in the UK, even when they've taken place abroad).
Importantly here then, I can find nothing in the provisions of the Bail Act 1976 to indicate that a person who committed an act (contrary to their bail conditions) outside of the UK could be prosecuted for it upon their return. So, as far as I can see, there are no restrictions upon travel in your case. (I'd still advise checking with your solicitor though; there might be a legal provision that I'm unaware of).
Even in the UK it would be necessary to examine the exact wording of the relevant bail restriction before deciding what did, or didn't breach that restriction. It's unlikely that such a vague term as 'not to go near' would be used. It's far more likely that something like 'not to be in the company of' would be used.
Further, even if there was a very tight restriction, such as 'not to go within 10 metres of', there would still normally be an exception such as 'except when going about your normal business'. (i.e. it wouldn't be a breach of the bail conditions simply to be shopping in a store when there happened to be an unaccompanied child shopping there at the same time).
