3-2-1 Fun Softplay Lewes (Soft Play)

The Outdoors Project Lewes runs outdoor after-school and holiday clubs for primary-aged children across schools in the Lewes and wider district, offering activities like den building, bushcraft, fire lighting and nature games. This is a term-time and holiday childcare service rather than a birthday party provider, with no specific birthday party packages listed.

Lewes Leisure Centre offers Magic Castle soft play sessions for children aged 0 to 10, running most days from 9am to 6pm and suited to birthday parties subject to availability. Pricing is per child, with siblings under one going free when accompanying another child.

Barney's Play is a family-run indoor play centre in Uckfield with themed areas including a sensory space for babies and toddlers, a jungle-themed main play area with slides and climbing features, and a role-play village called Barnington. Sessions must be pre-booked online, making it suited to toddlers and young children celebrating birthdays with supervising adults.

The Doves Play Barn offers exclusive hire of its wooden soft play barn for children aged six and under, with 1.5-hour sessions and food available from the on-site café or bring-your-own. It also runs inflatable park parties for all ages, with open or exclusive hire packages including optional food and unlimited squash.
