South Africa has some 87 documented thermal springs, although only about one-third of these have been developed into resorts of various sizes. The South African Spa Association (SA Spa Association) was also recently established, as a result of tremendous growth in the spa industry. There are 11 thermal springs in the Western Cape, seven of which have been developed into eight resorts.

Nestled between rugged mountains and the glittering coastline, the Western Cape of South Africa offers a treasure trove of natural wonders. Getting there is an easy flight, with plenty of places to stay.

Among these treasures lie steaming sanctuaries known as "warmwaterbronne" – natural hot springs offering the perfect blend of relaxation, rejuvenation, and cultural immersion. Let's embark on a journey through 8 popular Western Cape hot springs, uncovering their secrets, safety considerations, and the best time to embark on your geothermal escape.

These resorts are all year-round destinations, and are generally fully-booked during school holidays and long weekends. Most of them offer lower rates for mid-week and multi-day stays during off-peak periods, and are thus popular among retired people.

Of the undeveloped springs, Toorwater, near Uniondale, currently has no facilities or services, not even a swimming pool, but campers are slowly starting to return.

The Cape Winelands region has four thermal springs, two of which have been developed into large family leisure resorts (Goudini Spa and Avalon Springs), but which do offer a limited range of wellness and beauty treatments. The third (Baden Klub) operates as a private club, and the fourth (Brandvlei Hot Spring) is currently not developed. For more info and activities take a look at us as Featured on CTInsider.

8. Toorwater

Toorwater is situated 73 km from De Rust. While the name translates as “enchanted water”, it is not certain where this name originates, but according to Bulpin (1986), methane gas would often rise to the surface with the water, and the gas would sometimes ignite spontaneously, leading to the name “enchanted water”. Toorwater is a place with a few rooms and a pleasant camping ground, with beneficial water and a restful setting. Today the original building remains, but it is not in good condition, and although the water still flows as strongly as ever from a pipe, there are no longer any facilities for swimming or bathing. It is still possible to camp at the site, with permission from the farm manager, but currently there are no plans to redevelop Toorwater. Toorwater contains iron, lithium, manganese, nickel, phosphorous, rubidium and strontium.

9. De Kelders

De Kelders is located a few kilometers from Gansbaai. Two tepid (21°C) bathing pools, which contain water with high salt (sodium chloride) content, have been constructed at the end of an underground river, deep inside a sea-cliff cave. The entrance can be reached by descending a steep flight of stairs to the beach. The source of the water is believed to be about 10 kilometres inland, from where it flows underground at a rate of about one million litres a day. Currently there are no facilities, not even lighting. Although the caves and pools are not officially open to the public, arrangements to visit can be made with the owner. De Kelders contains arsenic, boron, lithium, molybdenum, phosphorous and strontium.

10. The Baths

The Baths has been functioning as a resort since the 1700s, and is characterised by its Victorian-style buildings, which give it an old-world feel, set in a narrow valley surrounded by groves of orange trees. The historic Victorian buildings have been converted into a number of accommodation units of varying sizes, and in addition there are a number of free-standing chalets. There are also caravan/camping sites, a restaurant and a shop.

The resort has a large outdoor thermal pool (38C), and a small rock pool, with the water being continually circulated and no chemicals added. The Baths contains cobalt, lithium, manganese phosphorous, rubidium and strontium. In addition there are five private spa baths, the hottest being 43C, and two whirlpools. Currently there are no health/wellness facilities and services, but the area offers good opportunities for outdoor exercise. Two hiking trails start and end at the resort, one taking about an hour, and the other four hours. For jogging and mountain biking, a gravel farm road continues for 15 kilometres beyond The Baths, with water approximately every four kilometres. Longer, circular routes are also possible. The resort also has tennis courts.

A wide variety of tourist attractions are located within easy reach of The Baths. These include the Olifants River Wine Route, which has seven wine cellars offering cellar tours and wine sales, and the Cedarberg Wilderness Area, known for unique rock formations and San rock art. Much of the area accessible for day trips from The Baths falls within the Spring Wild Flower Region, and during August, September and October the region is carpeted with wild flowers. An annual Wild Flower Festival and exhibition takes place in Clanwilliam every year in August, and lasts ten days.

Clanwilliam (72 km) is also the centre of the rooibos tea industry. Rooibos is a herbal tea known for its medicinal properties. Watersport lovers and anglers flock to Clanwilliam Dam, regarded by some as the best surface for waterskiing in South Africa. A particularly scenic drive, especially during the wild flower season, is from Clanwillliam over the Pakhuis Pass to the Bidouw Valley and Wupperthal, an old Moravian Mission Station with a well-known shoe factory, where hand-made „Veldskoene‟ can be bought, and visitors can watch the craftsmen at work.
