We are two aged 60s with a small campervan. Just spent two great nights at Abbey Wood. Spacious pitches, hard standings with grass and mature trees around them and toilet block with underfloor heating which delighted my husband! Day one we followed Green Chain walk on our bikes out to the Thames and then cycled along bank to Thames barrier. Sadly cafe closed  but luckily loos open. Cycled back using quieter roads and our A to Z. Day two we did 5 min walk to Abbey Wood station and caught train to London Bridge(£12 each including all day tube/ bus use). Easy 35 min journey brought us v close to Shard. We had a look round Shard shop/display area then walked from Tower Bridge to Lambeth Bridge enjoying sites along the way, ending up at the recently installed ' Rising Tides' sculptures in the river.  Then made our way using A to Z via Lambeth Walk ( yes we sang the song!) towards Imperial War museum - free entry. Had not allowed enough time here and will certainly go back.  Then tube and back to London Bridge  and 'home' to Abbey Wood. Great day out.  Ps just behind Guys Hospital we stumbled on nice grassy area with benches which was part of Kings College. Close by was a small Sainsburies where we bought a cheap picnic.
