Climb the O2’s iconic roof to a 52m summit and step inside the UK’s highest snow globe — a 2025–26 winter pop-up that pairs brisk skyline views with a festive photo moment. Practical preview, history, and what to pack for this guided urban climb.
You step onto the curved walkway and the city opens around you: the River Thames threads past, cranes punctuate the skyline, and the O2’s white tent skin dips away under your feet. The climb rises steadily to a 52‑metre summit where, for a short winter window, the UK’s highest snow globe waits — falling flakes, cinnamon-sweet air, and a staged photo moment framed by glassy high-rises.
Verified experiences and guided adventures in the surrounding area.

The O2 began life as the Millennium Dome, a turn-of-the-century project that reshaped the Greenwich Peninsula, itself built on reclaimed and industrial riverfront land. Walking its roof is an urban geology lesson: you’re on a modern canopy stitched over a former gas works and dockland, looking toward the spires and Georgian terraces of Greenwich and the glass towers of Canary Wharf.
Culturally, the climb ties into London’s appetite for repurposed spaces: stadiums, arenas, and rooftop experiences that turn vertical circulation into a view. Expect guided safety briefings, a slow, steady ascent on a covered walkway with harnessed railings, and 20–30 minutes at the summit to photograph the snow globe and skyline.
Practical notes: wear sturdy closed-toe shoes and layered clothing — wind on the roof bites even on mild days. Check the operator’s guidance for age, weight and accessibility limits before you book, and allow extra time for arrivals at North Greenwich station. Arrive with a charged camera, a small bag (larger packs may be restricted), and an appetite for a short, safe urban climb that finishes with a whimsical winter photo op.
The whole experience typically lasts around 90–105 minutes, with roughly 20–30 minutes at the summit for photos and viewing.
