Why not immerse yourself in London and learn about its history? The walks usually last two hours and are at a leisurely pace, with Colin Oakes as our very knowledgeable guide. Some of us stay for lunch together afterwards. We get the first train after 9:30am from either Rickmansworth or Croxley stations - the walks only cost £6. We have a maximum of 30 people per walk, so please make sure you book ahead.
