Boom Festival (Idanha-a-Nova, Portugal) 2027

Boom Festival returns to Boomland by Lake Idanha-a-Nova in central Portugal from 18 to 25 July 2027. Held every two years in odd-numbered years, the gathering runs on the private Herdade da Granja estate beside the Marechal Carmona reservoir, in the Castelo Branco district. The 2027 edition marks 30 years since the event began and stands as its 16th edition, a milestone the organisers have flagged under the 1997 to 2027 banner. As with any large psytrance and transformational music festival, the week combines round-the-clock dance floors with art, workshops and communal living.

The first Boom took place in 1997 and has grown into one of the best known transformational festivals in Europe, drawing a strongly international crowd to Portugal. The programme spans several stages, from the main Dance Temple to ambient and chill spaces, alongside talks, healing areas and large-scale visionary art installations. Sustainability sits at the centre of the project, with compost toilets, greywater treatment, solar power and waste separation forming part of how the site is run. The festival has been recognised for its environmental work in the past.

Practical details for 2027 are still emerging. The dates and venue are confirmed, and the official ticket portal operates through the festival website, though full sales phases and pricing are announced closer to the event. No line-up had been published at the time of writing, in keeping with Boom’s habit of releasing artist names in stages. Prospective visitors should follow the official channels for confirmed information.
