How do I see which nature houses are still available?

If you go to www.nature.house you will see the following screen:

Here you can look for an available nature house.

At Destination, nature reserve or nature house-ID you can enter a country, region or city. If you are looking for a specific nature house, you can enter the five-digit house ID there and you will be taken directly to the house page for this nature house.

At Arrival and Departure you can enter your desired period. You can then select an arrival and a departure day. If you are a bit more flexible in your arrival days, you can enter how many days earlier you would like to arrive. 

Under Number of guests you can indicate what your group composition looks like. You can also indicate whether you want to come with a pet or not.

Once you have entered the above data, click on the red 'search' button. The system will then show you the available cottages that match your search criteria.
