Short answer: Selected dates from Friday 27 November to Wednesday 30 December 2026, 4.30pm to 8.30pm, at RHS Rosemoor near Great Torrington. From £8 adult for RHS members and £13 for non-members, under-5s free. The 20 November start quoted elsewhere is Wisley, not Rosemoor.
Selected dates between Friday 27 November and Wednesday 30 December 2026, 4.30pm to 8.30pm. Last entry is before the end, so do not leave it late — check the exact time when you book.
Note "selected dates". The RHS publishes the range but not the individual nights anywhere on its site — the only place the actual open evenings appear is the booking calendar, so check that before you drive to Torrington on spec.
If you have seen 20 November to 3 January quoted, that is Wisley, not Rosemoor. The RHS runs Glow across five gardens on different dates and the headline range belongs to the Surrey one. Rosemoor is the shorter run.
The one fixed thing: a silent disco on Friday 11 and Saturday 12 December.
The member discount is large enough that if you were thinking of joining the RHS anyway, this is the month it pays for itself.
Rosemoor has not published parking cost, trail length or accessibility detail for Glow. If any of those decide whether you go, ring the garden first.

RHS Rosemoor’s own event listing, which states the dates and the year together, read 3 November 2026. Rosemoor’s separate Glow page still carries 2025 wording in places, so we have not used it.
