For a Half Day

Blue Lagoon: Located in the lunar-like landscape of lava fields, the Blue Lagoon was accidentally created by the run-off water from the Svartsengi power station. The reputed health benefits (particularly for skin ailments) of its mineral-rich, geothermal seawater have made it one of the most visited locations in Iceland. Massages are also on offer and spa beauty products, including mud from the lake, are available too. The Blue Lagoon (tel: 420 8800; website: www.bluelagoon.is) is situated on the Reykjanes peninsula, about 50km (30 miles) southwest of the city. Bus 5 leaves Reykjavik's central bus station three times a day (journey time - 40 minutes). There are also half-day excursions available (see Bus Tours in Tours of the City). The spa is open daily 0800-2100 in the summer (Mid May-Aug), and 1000-2000 in winter.

For a Whole Day

Golden Circle: The waterfall of Gulfoss, together with the famous geothermal area at Geysir and Thingvellir (the site of the old Icelandic parliament), form the main attractions of a round tour that has become known as the ‘Golden Circle'. Considered to be Iceland's most beautiful waterfall, Gulfoss ('golden falls') is a two-tier waterfall in a huge gorge carved out by the mighty glacial River Hvítá. The spouting Geysir (the original that gave its name to the world's geysers) ceased to erupt earlier this century but fortunately its faithful stand-in, the nearby Strokker, spouts and sprays every five minutes or so. The site also includes hot springs that are coloured by mineral deposits, steaming vents and warm streams.

A host of operators offer day trips by coach or 4x4 vehicles. You can also add a snow scooter ride, white-water rafting or horseriding to the experience with Iceland Total (tel: 585 4300; website: www.icelandtotal.com). For those short of time the Golden Circle can be combined with a visit to the Blue Lagoon, although the combined tour makes for a very long day. It is possible to get to all these destinations by public bus, but not all in one day as services are infrequent. A tour or private transport is much more advisable.
