Hot springs are one of the great pleasures of the countryside around San Miguel de Allende, and La Gruta is the best known. The resort sits about ten kilometres out on the road toward Dolores Hidalgo, roughly twenty minutes by car from the centre, and is set among gardens with several thermal pools. The signature feature is the grotto: a narrow, enclosed passageway that leads you into a domed stone chamber with a hot spring pool, which feels more like a hidden cave than a spa. Beyond it, the gardens hold further pools of different temperatures, with loungers for resting between soaks. The resort also has a restaurant, a cafeteria and a bar, and a spa offering treatments such as reflexology, aromatherapy, Swedish and holistic massage. It suits couples, groups of friends and families, and it makes an excellent counterpart to a morning of sightseeing. Bring swimwear and a towel, and go with nothing planned except lying back in warm water.
How a visit works
You arrive, pay at the entrance and are free to move between the pools at your own pace. The grotto pool is the hottest and the most atmospheric, and you may find it busy at peak times, so go early or on a quieter day if you want to enjoy it in peace.
Lockers, changing rooms and showers are provided, and the restaurant and bar mean you can stay for a long lunch. Treatments in the spa usually need to be arranged on site and may be extra, so ask about availability and prices when you arrive.
Practical tips
Opening days and hours can vary, with some weekdays closed for maintenance according to visitor reports, so confirm before making the trip. Bring cash as well as a card, and wear swimwear in the pools. Some areas, such as the hottest grotto pool, can have restrictions for young children and for guests with heart conditions or low blood pressure, so check the rules on arrival. Drink plenty of water, as the heat can be tiring, and allow time to rest between soaks.
Who it suits
Anyone who wants to slow down. It is ideal after a day of walking or the sanctuary visit, since the nearby town of Atotonilco is on the same side of San Miguel. Couples will enjoy the romantic setting, families can use the gardens and the larger pools, and solo travellers will find it a restorative half-day. A taxi from town is simple, and many visitors combine it with lunch at the resort before returning in the afternoon.
