Natural Hot Spring River Hike - Reykjadalur HotSpring Thermal River

Today we are still in Iceland and doing a hike to a natural hot spring river. The hike was very fun and fairly easy I would say 2.5/10 for difficulty as there is a nicely well maintained trail the whole way and gradual incline.
The best part was the end where you get to bath in the river which was quite warm. We brought water shoes but I think they were unnecessary. A towel is a must though. There are also areas to change but they are not private.
