The walk, stop by stop

Marmalade the octopus leads the way. At each stop a new character needs help, children take on a challenge, and the explorer who led it earns a badge. Along the way everyone hunts for rainbow pearls.

  • Example review
    We came for a quick walk and stayed two hours. My seven-year-old ran ahead to every plaque and the little one did the stomping challenges with total commitment. The Rainbow Pearls is now requested at bedtime.

  • Example review
    I bring my group every Thursday now. The little challenge versions are perfect for the toddlers and the older ones love being the 'map keeper'.

    Leah, childminder, explorers aged 2 to 5

  • Example review
    Three kids, three different ages, zero complaints about walking. That has never happened before. The narration is genuinely funny and the badges at the end were a big hit.

  • Example review
    Ollie is not an outdoors kid. He did the whole of The Rainbow Pearls and then asked if there was another one. That's a five from us.
