Hundreds of visitors have attended a festival in Brecon encouraging people to lead a more "green" lifestyle.
Dozens of tents were set up alongside the River Usk at Brecon Promenade for the event on Tuesday.
The festival, under the banner "your planet needs you", marked world environment day.
It was hosted by Brecon Beacons National Park Authority and Powys County Council.
More than a dozen different organisations and community groups attended, offering energy advice and recycling tips.
It offered visitors the chance to explore how they could help the planet and the national park, and change their lifestyles.
Jemma Bere, sustainable communities officer for Brecon Beacons National Park Authority, said visitors could explore how "individual greener lifestyle choices such as composting and recycling, using energy efficient light bulbs and electric cars" could contribute to a "better environment in our national park".
