Orford Ness, Suffolk: A Family Day Out on the Cold War Shingle Spit (NT)

Orford Ness is the 10-mile shingle spit that runs south from Aldeburgh, separating the river Alde from the open sea. From the 1910s through to the late 1980s it was a top-secret military research site — radar was developed here in WWI, atomic-weapons trigger components tested in the Cold War, and the abandoned ‘pagodas’ (concrete blast-test buildings) still dot the landscape. Now run by the National Trust, it’s accessible only by their boat from Orford Quay.

Visitor essentials

What to expect on a family visit

A long day. NT ferries run a few days a week from late April to October — pre-book online, expect to be on the spit for around five hours between boats. Bring water, a packed lunch and walking shoes. It is genuinely wild — terns, dragonflies, sea kale, bare shingle punctuated by abandoned concrete bunkers. Not suitable for very young children who tire on rough ground; perfect for older primary children and teenagers who can engage with the history.

Planning your visit to Orford Ness

Opening times, ticket prices and seasonal closures vary across the year. Check the live page on National’s own website for the day you are planning to visit — this is the only authoritative source.

Plan your route: the relevant Ordnance Survey map for Orford Ness is OS Explorer 212 — Woodbridge & Saxmundham. Mobile signal is patchy across many of these places — a paper or downloaded OS map is more reliable than your phone for finding car parks, footpaths and the way home.

Visiting more than three or four NT places a year? National Trust membership covers entry and parking — and there’s a Free Guest Pass on annual Direct Debits at the moment.

Correct as of 28 April 2026 — please check before you travel, especially on Bank Holidays, Easter and between Christmas and New Year.
