The Outdoors Project Lewes

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.

3-2-1 Fun provides luxury soft play packages, bouncy castles, a bubble house, ball pits and light-up numbers for children's parties across Lewes and the wider Sussex, Surrey and Kent area. Soft play suits under 4s while bouncy castles are sized for children up to 12, with standard hire of up to four hours and optional name or age personalisation.
