Heathrow to Burnham Market

Piccadilly Line (tube) to King’s Cross St Pancras. Train from King’s Cross to Kings Lynn. Taxi from there.

Tricky one. The nearest station is Kings Lynn, 25 miles away.
From Heathrow take train to Paddington, tube to Kings Cross, then train. Journey time c. 3 hours - see Trainline for options.
Then it's taxi or bus (hour and a half).

While this can be purchased as a through fare from Heathrow don't do that as the fare is £76.70.

Buy it as rail fare into London, then a Kings Cross to Kings Lynn Single-
Monday to Friday an Anytime Day Single is £47.70
Saturday and Sunday a Super Off Peak Single is £36.60

All fares are before any relevant National Railcard Discount.

There is a way to get the Monday to Friday fare down further if you use the Elizabeth Line from Heathrow, involving the use of a Day Travelcard, and Boundary Fares- after 0930 a Zone 1 to 6 Travelcard is £16.60, then buy a Boundary Zone 6 to Kings Lynn Anytime Day Single at £41.90- both fares get railcard discount- but that may be too complicated.

How many of you are there, and where are you going after Burnham Market?

If you're not in a hurry and don't have vast amounts of luggage, the #36 Coastliner bus from Kings Lynn bus station, a short walk from the train station, runs through Burnham Market. It's takes 1½ hours but costs only £3pp under the current national capped bus fare scheme. I have to say though that Burnham Market isn't a very convenient place from which to tour Norfolk without a car, if that's your plan

Thank you for your reply. It probably doesn't surprise you that I know very little of North Norfolk (being from the US and having never been to England). It was recommended to me as an area for easy/scenic cycling/walking along the sea... something that would be satisfying to my wife. I'm a bit more adventurous than she, but I need to come up with a two week plan that can satisfy the both of us. Currently, I am thinking of one week based in Burnham Market and one week based in Aylsham. We will have no car. We are open to other possibilities, but I am certain that we would prefer smaller, historic communities. A relaxed two weeks with opportunities for both walking and cycling is what I am looking for.

Consider Sheringham as a base. Elizabeth Line from Heathrow to Liverpool Street, train to Norwich then change to the branch line to Sheringham. As well as the train station back to Norwich (well worth a day of your time), there's a heritage steam railway, a regular bus service along the coast, lovely walks along the coastal path and to beautiful Sheringham Park, and a bike hire centre.

I like ck99's suggestion of Sheringham. For all the right reasons

I was thinking similarly- tho I would probably go with Cromer over Sheringham personally (busier, more to do). You can also get the train directly to Cromer from Norwich. If you want to explore more of the coast once you get there you can take buses up to Wells-next-the-Sea and from there transfer to another bus which will take you up to Huntingdon. If you like walking at all definitely check out the North Norfolk Coast Path, it really is beautiful (tho I don't recommend the section just east of Cley as it's mostly shingle and very hard to walk thru).

Thank you Cat VH and Nigei for your comments and suggestions. As a consequence, we are now looking at Sheringham for a week followed by Aylsham for a week. I think we will also add in Norwich for a couple of days and stay in the historic district.

Similar question as before: traveling from Heathrow and between Sheringham, Aylsham, and Norwich. The order in which we visit the three locations does not matter. Also need to get back to Heathrow from wherever.

You would do Norwich first- Elizabeth Line Heathrow to Liverpool Street, then Greater Anglia express train to Norwich every 30 minutes. Or National Express bus direct to Norwich roughly every 2 hours, then Sheringham by train then there are two bus routes- the 18/18a and the 44/X44/X41 from Sheringham to Aylsham- the latter is a roundabout route from Sheringham to Norwich- https://www.sanderscoaches.com/

Aylsham also has it's own steam railway- narrow gauge unlike the one from Sheringham- https://www.burevalleyrailway.co.uk/

Thank you very much. As a first time traveler to England, I truly appreciate your guidance.
