Beyond the Blue Lagoon: Family-Friendly Hot Springs in Iceland

When people dream of visiting Iceland, the Blue Lagoon usually steals the spotlight, but as a mum of three and Family Lifestyle Publisher, I’ve learned the best family memories often happen beyond the tourist trail. Iceland is filled with hidden geothermal gems where you can relax, explore, and let your little adventurers splash about safely in family-friendly hot springs.

From natural rivers to steamy lagoons, these family-friendly hot springs blend wellness, wonder, and that unique Icelandic magic that keeps everyone, kids included, completely mesmerised.

The Blue Lagoon usually tops the list of attractions on family holidays to Iceland, but the country has far more to offer than its most famous spa. It’s renowned for its glaciers and the magical Northern Lights. Iceland is also home to countless natural hot springs, many of which are family-friendly. 

If you’re planning a trip to the Nordic island, check out my favourite spots that prove Iceland’s hot spring scene is about so much more than one lagoon.

The Secret Lagoon (Flúðir)

this for later

Located in Iceland’s Golden Circle, the Secret Lagoon (Gamla Laugin) is the country’s oldest swimming pool, dating back to 1891. Unlike the sleek, touristy vibe of the Blue Lagoon, the Secret Lagoon feels closer to nature.

The water stays at a cosy 38–40°C year-round, making it ideal for the whole family alike. You’ll appreciate its simplicity, while the kids’ visitors will be fascinated by the small geothermal area just a short walk away. Steam vents rise from the ground, and a tiny geyser erupts every few minutes, a natural wonder that makes the experience even more magical. 

Laugarvatn Fontana

A visit to Laugarvatn Fontana offers a complete wellness experience. Nestled by the shore of Lake Laugarvatn, the spa features a mix of geothermal baths at varying temperatures, as well as steam rooms built directly over bubbling hot springs. You can relax in the pools while the children enjoy the novelty of hopping between different baths.

What makes Laugarvatn Fontana particularly special for families is the geothermal rye bread experience. Locals bury dough in the hot black sand, where it bakes underground for 24 hours. Visitors can watch the process, then enjoy warm, freshly baked bread with butter. 

Myvatn Nature Baths 

The “Blue Lagoon of the North” is a must-visit during your Iceland holiday in the Lake Myvatn region. The geothermal spa features the same milky-blue waters rich in silica but in a calmer setting than its more famous cousin, complete with a volcanic landscape backdrop for your swim.  

The Myvatn pools have shallow areas suitable for children learning how to swim, and the less crowded atmosphere makes it easier to relax together as a family. After you dip in the waters, you can visit the Goðafoss Waterfall and the Dettifoss Waterfall, Europe’s most powerful, or explore the horseshoe-shaped Ásbyrgi Canyon.

Reykjadalur Hot Spring Thermal River

For adventurous families, Reykjadalur (“Steam Valley”) offers a more natural experience. Instead of a built-up spa, it’s a natural hot river where you can bathe outdoors. You’ll begin your day with a scenic 45–60-minute hike through a valley dotted with bubbling mud pools and steaming vents. 

While the walk itself is part of the fun, the reward is reaching the warm river where you can find a comfortable spot and relax in the naturally heated water. It’s a unique excursion that combines exercise in a breathtaking landscape with a geothermal rarity that the kids won’t soon forget.
