Kathryn and boyfriend Daniel Padilla are spending 10 days of quality time together in the Nordic country.
The ABS-CBN actress writes in one of her Instagram posts: "Three of my favorites in one photo: hot chocolate, nature, and my love
"How did I get so lucky?"
In an earlier post, the Hello, Love, Goodbye star gushes, "Iceland, you are unbelievable."
The post showcases the mountain ranges of Iceland.
Another post has Kathryn standing by a lake, highlighting the natural vibrant colors of the region.
Here's a cute candid photo of KathNiel, the couple's moniker, with one of Iceland's many waterfalls as backdrop.
On their first day in Iceland, the two were lucky enough to see the Northern Lights.
