Just after the bridge in Tnine, signs off the main road point down a dirt track towards the organic botanical gardens of a Franco-Moroccan natural bath-product company that combines Berber herbal remedies with modern aromatherapy. The garden certainly smells great, and a footbath and foot massage with organic essential oils (Dh250) is just the thing after a trek.
If you're in Tnine for the Monday souq, the gardens are also a good place to stop for lunch (Dh60 to Dh80).
