Coming from Rethimno, just before entering the village of Spili you can visit the Maravel Gardens.
The gardens are full of medicinal and aromatic herbs. Just take a look and enjoy the different scents.
In the Maravel Shop you can buy all kinds of herbs, tea, olive oils and herbal products.
The cache is located outside the gardens.
To find the box you have two options. You can walk through the garden and at the end pass the gate and turn right.
If the garden is closed you can park at WP trailhead N35° 13.193 E024° 31.479 and follow the small path.
