Sigöldugljúfur, also known as the Valley of Tears, is a hidden gem in the Icelandic Highlands. This canyon is famous for its abundance of waterfalls and stunning blue waters, making it a dreamy oasis-like spot for hikers and photographers. To get there, you'll need a 4x4 vehicle and some hiking gear, but the journey is totally worth it for the breathtaking views and peaceful atmosphere. Just remember to pack some snacks and fill up on gas before heading out, as there are no amenities nearby.
