Children friendly !!
Would agree with most of your replies but would also cast a vote for Southwold. Friendly and between the visits moorings and town there is 1/2 mile of fields/heather/blackberry bushes and another footpath goes via the fab beaches. Wrong time Stone point can get busy.
We are based Ipswich
Brightlingsea !!! Two yacht clubs, swimming pool, water taxi to/from pontoons, restaurants, marina, and of cours, Dylan's favourite place ..
OBVIOUSLY i AM NOT BIASED !
East Coast Children
Our children are now 14 (x2) and 23 so the priorities have changed somewhat, but when they were little some of the places that worked for them were:
Stone Point, including leaving the boat at anchor and taking the dinghy up into Walton on the tide for a trip to the pier and shopping, beach and long grass ocasional wild camping,
Hamford Water with dinghy trips up the creeks to see the see the seals (loads of them),
Titchmarsh child friendly bar plus crabbing in the marina and walk/cab into town for beach, pier, fish and chips etc.,
Brightlingsea for crabbing (142 in an hour caught on squid is the boat record) swimming pool, park with playground, easy shopping, bus into Colchester for cinema and posh swimming pool with flumes etc longish walk into Clacton via Point Clear then cab back
Burnham for trains to Southend, cinema, park with playground, long walk along the seafront, dogs, easy shopping
Calais, good beach with trampolines etc. easy shopping, often lots of other kids on boats (Dutch and Norwegian), fishing in the marina, often fun fair etc in town square,
Ramsgate, good beach, donkey rides, cinema, shopping, bus to Margate for funfair that I think has now closed down for good, walk to Broadstairs with a stop to see the parrots in the park, ice cream parlour
