The oldest public art gallery in London also is my local gallery in my neighbourhood. Opposite to the Dulwich Park where I walked with my puppy regularly. They have great collections of Dutch paintings as well. My husband found the original Dutch painting of the print at his home he was growing up with.
This is a great, free and lesser known spot in London. A glass lift takes you up the side of st.Paul's cathedral right out onto the roof terrace of this shopping centre. A great view over London.
Camping in London? Absolutely! This is one of a few sites which has direct access to Epping Forest from the campsite. Easy to get to by tube, with a fire field and 50 acres to spread out in, this is a great place to recharge your batteries.
