ION Adventure Hotel

ION Adventure Hotel

A landscape of lava fields, rolling hills, and hiking trails sets the scene at this boutique hotel that was once an inn for workers at the nearby Nesjavellir Geothermal Power Plant. Given its location just 30-minutes from south-west Iceland’s UNESCO-protected Þingvellir National Park, it is the ideal base for catching clear views of the northern lights during the winter, bathing in thermal hot springs, and enjoying activities such as snowmobiling, ice caving and rafting. You’ll also be just under an hour from Reykjavik and within easy distance of the Golden Circle route’s numerous attractions. 

All of the 44 bright rooms have minimalist Nordic décor, soothing neutral hues, contemporary furnishings, light woods, grey walls, and paintings, photographs or murals by modern Icelandic artists. Amenities include beds with fair-trade organic linens, desks with lamps, flat screen TVs, tea and coffee-making facilities, complimentary Wi-Fi, and en suite bathrooms with showers.

Elsewhere, you’ll find a geothermal outdoor pool and a small spa area with a sauna and relaxation room. A selection of treatments with Icelandic herbs is available, booked at least one to two weeks in advance. There’s also a sleek restaurant serving farm-fresh Nordic cuisine as well as a glass-walled bar for end of day beers, spirits, wines, light snacks, and panoramic views of the surrounds.

Located on the Golden Circle route, you’ll be a 30-minute drive from the UNESCO-protected Þingvellir National Park and about an hour from the Geysir Hot Spring Area. The town of Selfoss is 40 minutes away and offers cafes, shops, restaurants, and an outdoor swimming pool with hot tubs. You’ll also be just under an hour’s drive from Reykjavik.

Food and drink

Seasonal dishes such as farm-fresh lamb and fish feature on the menu at Silfra, the hotel’s restaurant named for the tectonic rift in Þingvellir. A buffet breakfast is available every morning. For beers, spirits, wines, light snacks, and panoramic views of the surrounds, the glass-walled Northern Lights bar is an ideal spot.


Children are welcome at ION Adventure Hotel and extra beds can be added to the Deluxe rooms. The handyman’s friendly dog, Tara, works a daily 8am to 4pm schedule with her owner and may offer to accompany you on a hike around the hotel.

Facilities and activities

In addition to a geothermal outdoor pool, there’s a small spa with a sauna and relaxation room. Massages and facials with Icelandic herbs are available, although advance bookings of at least one to two weeks are recommended. If you’re hoping to see the northern lights, staff will arrange a nightly wake-up call for when they are visible. 

Our opinion

We love the peaceful setting, friendly service, and sleek Nordic decor at this stylish boutique hotel near the UNESCO-protected Þingvellir National Park. The panoramic views from the glass-walled Northern Lights bar are especially memorable.
