The Retreat at the Blue Lagoon

The lagoon describes The Retreat as sophistication, serenity and luxury. The Retreat Spa, a five-hour day visit with eight subterranean spaces, a private changing room for two and the Retreat Lagoon, starts at EUR 579 per changing room, and the lagoon's Michelin-starred Moss restaurant is on the property. The lagoon is 21 km from Keflavík Airport, which makes it a first or last night. Details of the area are in best hotels near the Blue Lagoon.

Hotel Rangá

Hotel Rangá is in South Iceland, within reach of waterfalls, glaciers and black sand beaches, and its on-site observatory has telescopes and expert guidance. Room rates start at €431 for a Standard room and reach €1,367 for a Master Suite, and a seasonal Age of Aurora package starts at €1,328. For the sights it sits near, see South Coast day tours and Seljalandsfoss.

ION Adventure Hotel

ION is at Nesjavellir by Lake Thingvallavatn: take road 36 toward Þingvellir, then road 360 toward Nesjavellir. Road 435 is closed from October to May, though a GPS may still show it. The suites are the point: the Thermal Junior Suite (37 m², lava field view, complimentary minibar), the Lava Suite (54 m², lava field view, minibar, private sauna) and the Aurora Suite (65 m², private sauna, lake or mountain view). The hotel has Silfra Restaurant and The Northern Lights Bar serving New Nordic cuisine, and the Lava Spa. The hotel does not publish rates on its page, so compare on Booking.

What the price gap buys

At the lagoon, The Retreat starts EUR 923 above Silica Hotel (EUR 1,685 against EUR 762). At Hotel Rangá, a Master Suite at €1,367 costs €936 more than the Standard room at €431. ION lists nine room types from a 15 m² single to the 65 m² Aurora Suite, so the choice there is room size and sauna rather than a single headline rate. In every case, rates depend on date and season, so compare on Booking before deciding.
