Serpentine Green

Welcome to Lost World

Lost World is Vivacity's exciting new Amazon themed soft play and activity centre in Serpentine Green, Peterborough. Young adventurers of all ages can play, climb, slide and explore, seven days a week.


Volcano Slide

Climb and slide in the middle of Serpentine Green on the only 360° volcano slide in Peterborough. Young adventurers can enjoy a quick 15 minute treat on the volcano, or as part of the full Lost World experience.

Please note that children are required to wear soft shoes or trainers on the slide. The volcano is suitable for children aged 4 to 14. All adventures must be supervised, accompanying adults can access the slide area for free.

Soft Play & Interactive Climbing Games

Explore our two soft play areas, featuring a variety of fun physical challenges that are appropriate for adventurers of all ages, from toddlers to 14 years.

Within the soft play area and included in the soft play entry, our interactive climbing game is the only one of its kind in Peterborough. Including 2 person challenges, explorers choose the activity that they want from a choice of multiple games that are sure to get the heart racing.

Please note that children are required to bring and wear socks for the duration of their visit. Soft shoes or trainers are required on the interactive climbing game.

Accompanying adults can enter Lost World free of charge.

Climbing Walls

With five individual climbing stations, our climbing wall stands 5 metres high and offers a safe and exhilarating climbing experience for explorers aged 4 and upwards (including grown-ups), with safety equipment and safety briefing provided before each session.

Please note that climbers must wear soft shoes or trainers to climb on Lost World’s climbing wall.
