I don't know if you will believe me but these photos with the waterfall are taken at ... sea!
Balchik city in Bulgaria, Black Sea resort. Not in the mountains. In this city, at the seaside there is a castle, the castle of Queen Maria of Romania. Around the castle was arranged a beautiful botanical garden, a garden developed on terraces.
Balchik is a city built on hills and from these hills flow many small rivers, here are many springs that feed these rivers. Such a river was used for this waterfall built in the castle garden.
Everywhere I go I usually take a lot of photos, especially with the smartphone because it is more comfortable and I can move faster so as not to lose an image that I find interesting. Especially street snapshots.
