Came on to say this will be a great year to take your kids places, as long as social distancing lasts. The advice on how places are rammed is based on pre-pandemic visits.
Natural History Museum has been sooo quiet. We have visited three times in the pandemic and it's been bliss. Most museums have 15% of their normal visitor numbers.
I blog about London for families over on museummum.com and on instagram.com/museummum so if you follow me there you'll see what we do and recommend.
I have a post on visiting the NHM museummum.com/2021/03/19/natural-history-museum-london/, all the photos were taken during the middle of the day when it was open to the public. You can see how quiet it is.
London Zoo is fantastic. Mail Rail at the Postal Museum is fun, and the Horniman Museum is good for younger children with a little aquarium, butterfly house, animal walk through and usually a hands on exhibition, plus a park, farmers market and family events.
London Transport Museum is a good one for those ages, kids go free and your ticket is valid for a year so works out good value. There's lots to clamber on and special play areas and driving simulators.
Tower Bridge has the glass walkway and does family events, if you visit on a family day and get your ticket stamped you can come back on any other family day for a year for free. Nearby there's fountains at More London for hot days. We also really like the Royal Mews, it has real horses and does family tours and events too, tickets also valid for a year. And Buckingham Palace is allowing picnics in the grounds this summer for the first (and maybe only) time ever!
When numbers start picking up again look at special openings for children with autism and other conditions which mean they may benefit from a quieter visit. And always ask for a free carer ticket!
Anyway, lots more ideas on the blog and my social channels. Have a great year enjoying your days out and let me know if you have any questions.
