It’s a hike! It will easily take you about 1.5 hours to go up (depending on where you start) and about 1 hour back down, if your knees allow it. If not, count on 1.5 hours down as well. Along the way, you will see several spots where steam or boiling water comes straight out of the ground. The hot water stream itself is very hot in some places and quite shallow, but overall a very nice experience.

⭐️⭐️⭐️⭐️⭐️ A magical experience like bathing in nature’s spa! Reykjadalur Hot Spring Thermal River is truly one of the most unforgettable places in Iceland. The hike to get there takes about 45–60 minutes depending on your pace, and every step is worth it. You walk through stunning mountain landscapes, bubbling mud pools, and clouds of geothermal steam and at the end, you’re rewarded with a warm river flowing through the valley where you can relax and soak in nature’s heat. The water temperature changes as you move along the river, so you can easily find your perfect spot. It’s peaceful, scenic, and feels completely natural no artificial pools or crowds like in some tourist spots. Tip: Bring good shoes for the hike, a towel, water, and maybe a small snack. There are no facilities up there, but that’s what makes it feel so pure and wild. Go early in the morning or later in the evening for a quieter experience. An absolute must-do if you visit Iceland it’s not just a place to bathe, it’s an experience you’ll never forget. ♨️🇮🇸🌄

Amazing experience with beautiful views! Prepare for a hike and not for a walk, the way towards the hot spring is quite steep from the beginning until the middle. I am a very active and fit person and it took me around 1 hour of fast hiking. So if you want to take it slow, prepare for around 1.5 hours :) No closed changing rooms, everyone is just changing behind a wooden wall.
