Lavenders bloom from June to July, and lavender fields are really spectacular. They are also popular hiking destinations as visitors are often allowed (for a fee) to pick lavenders they can later use as they please. If you are looking for a one-day adventure with family or friends where you can wander a bit in nature without going too far out into the wilderness, visiting a lavender field can be the excellent choice.
In Hungary, you can find many pick-your-own lavender fields (find a map here). Before you leave for your adventure, it is worth checking out the website or Facebook page of the field you intend to visit so you can confirm if it is indeed open for visitors or if lavenders are currently in bloom at that specific site. You should also check what facilities the site offers, and if you need to have any tools.
In most cases, you will need to bring your own shears, and you will most certainly be advised to bring a hat, water, and sunscreen, since there is no shade on the fields. At the same time, many sites will have a shop where you can buy sachets for the dried lavenders, or products made of lavender, such as lavender oil or lavender syrup. You can even find workshops where they can teach you some of the uses of lavender or other handy crafts.
