Hunstanton lifeboat crew carried out two rescues in two days at Brancaster this week.
On Wednesday at around 5.50pm, two adults and two children were rescued from Scolt Head Island after being cut off by the rising tide.
The day before, the RNLI was alerted by Coastguard officials at around 4.50pm to reports of two women, two children and a dog stranded at the island.
Everyone in both rescues was taken in the hovercraft to safety.
Visitors made their way back to the coast this week with the better weather and Easter holidays.
People are expected to head for the seaside and other West Norfolk attractions over the long weekend after the Covid “stay at home” restriction was lifted on Monday.
The RNLI is reminding visitors to respect the water and be aware of tides, strong currents, sandbanks and channels.
A Norfolk police chief is urging people to be “sensible and cautious” as restrictions ease.
