Is ION Adventure Hotel Worth It?
Winter Roads, Lava Spa & Golden Circle Base

ION Adventure Hotel sits in the Nesjavellir valley, near Þingvallavatn lake. The official address is Nesjavellir 801. It’s roughly a 40-minute to one-hour drive from Reykjavík, though actual times shift with the season and road conditions. The location is unusual: it connects west to Þingvellir and east to the Golden Circle, but it isn’t tucked into a typical town street. If you want to pop out at night for a supermarket or a second restaurant, there’s no urban fallback here.

Check the Winter Access Route Before You Book

ION’s official guidance is clear: Route 435 is closed from October to May, even if your GPS still shows it as an option. To get from Reykjavík to the hotel in winter, take Route 36 to Þingvellir, then switch to Route 360 towards Nesjavellir. This isn’t a minor detour; if you follow the navigation to a closed road, you’ll be turning around, hunting for signal, and checking maps in the cold, which eats into your Spa booking time.

In summer, Route 435 can be a more direct mountain connection, but you should still check conditions before setting out. The hotel’s valley location gives it a distinct landscape, but it also means fewer nearby shops, gas stations, and casual restaurants. Stock up on water, snacks, and phone chargers in Reykjavík or en route so you have the bandwidth to enjoy the Spa once you arrive. This "refuel first, then enter the valley" approach is far less stressful than realizing your phone is dead after you’ve checked in.

Choose the Room by How Much of the Evening You’ll Spend at the Hotel

The official room page lists a Single Sub-Parterre (15 sqm), Classic Double/Twin (20 sqm), Standard Double/Twin (20 sqm), Patio Room (25–28 sqm), Deluxe Double (20 sqm), Junior Suite (24–30 sqm), Thermal Junior Suite (37 sqm), Lava Suite (54 sqm), and Aurora Suite (65 sqm). If you’re just using the hotel as a place to sleep, a 20 sqm room does the job. If you plan to wait for the aurora in the room, travel with kids, or need space for wet jackets, the extra room in a Patio or Suite is much more useful.

The Thermal Junior Suite sleeps two adults and two children, the Lava Suite has a private sauna, and the Aurora Suite offers lake or mountain views. You don’t need to upgrade for every trip: if you’re leaving before dawn for the Golden Circle, you’ll only use the private sauna for a short time. But if you’re staying an extra night to rest, the price difference might buy you an evening where you don’t have to drive anywhere.

Plan Lava Spa, Silfra Restaurant, and the Evening Together

The Lava Spa is ION’s core draw, Silfra Restaurant serves local-ingredient-focused dining, and the Northern Lights Bar faces the valley and night sky. Having these three elements in one hotel turns "staying near the sights" into "no driving after arrival." Public info suggests Silfra is open roughly 07:00–21:30 and the bar 17:00–23:00; breakfast inclusion, Spa time slots, and restaurant seating should be confirmed for your specific dates.

The ideal rhythm is to finish Þingvellir in the afternoon or depart from the city, check in, and then eat according to your Spa booking. Don’t pack three Golden Circle sights into the morning and treat the Spa as an afterthought at night; the extra cost of the room is hard to justify that way. If you want to combine a soak with other activities, read our Fontana vs. Secret Lagoon comparison first to make a real choice between a scenic lagoon and a hotel-based Spa.

ION vs. Grímsborgir: Resort Experience or Mid-Route Efficiency?

For planning, use a nightly range of roughly HK$2,400–7,500 (approx. NT$9,600–30,000). Room type, season, breakfast, and Spa arrangements will shift the total. This isn’t a fixed quote, but it shows ION shouldn’t be compared to a standard Golden Circle room on bed price alone. If you’re only sleeping for six hours, the price difference should go toward activities or transport. If you’re keeping your afternoon, dinner, Spa, and next morning in the valley, the room rate starts to serve its full purpose.

One Night, Two Nights, or Your Final Night: Where ION Fits Best

One night: Put Þingvellir in the first half of your arrival day, check in in the afternoon, and finish with the Spa and Silfra in the evening. The next day, head to Geysir and Gullfoss, then go to Selfoss or Hella depending on your direction. In winter, allow a road buffer when arriving via 36/360; don’t schedule your Spa booking at the tightest possible arrival time.

Two nights: Take it slow from Reykjavík on day one, do a full Golden Circle loop on day two, and return to the hotel in the evening. This is how you actually use the room’s terrace, bar, and Spa. If you’re leaving at dawn both days, ION becomes an expensive bedroom. Before booking, ask if you’re really willing to keep one afternoon free from sightseeing.

As the final night before a flight: Be careful. ION is about 80 km from KEF airport. Car return, refueling, and flight times must all be counted. For early flights, staying near the airport or in Reykjavík is usually easier to control. The hotel works well as a mid-point for the Golden Circle or South Coast, but isn’t necessarily the best insurance night before a flight.

If the weather changes, keep the nearby valley views, restaurant, and Spa, and push the farthest stop (Gullfoss) to later. Once roads clear, you can do the eastern end. If you’ve booked activities, remember that pickup ranges don’t always include Nesjavellir; check meeting points item by item. Getting these details right first is what makes ION an asset in your trip, rather than a beautiful hotel you have to rush to.
