Guanacaste sits on one of the most volcanically active parts of Costa Rica, and the hills inland from the coast hold natural hot springs and thermal pools heated by the same geology that built the great cones of Rincon de la Vieja. A thermal day is the opposite of an adrenaline tour. You soak in a series of warm pools of different temperatures, rest in shaded gardens, and eat a lunch that is part of the programme, at a pace set by you. This offering is run under the Sensoria name and is described as a thermals-and-lunch experience, which suggests a calm day of wellness rather than a full activity programme. For travellers who have spent days on boards, boats and bikes, it is a welcome change. Thermal pools are popular because they suit nearly everyone: couples, groups of friends, parents with grown children and solo travellers who want a quiet day. The mineral-rich water is warm rather than scalding, and many guests find it relaxing for sore muscles after surfing or horse riding. The details, including how many pools there are, the temperatures, whether mud treatments or massages are offered, what lunch includes and what time the day starts, depend on the option you choose, so read the inclusions on your ticket and confirm the meeting point when you book. Because the site is inland, the drive from Tamarindo is a significant part of the day, so plan accordingly.
How it works
You reserve a date and arrive at the location given when you book, where staff check you in and explain the facilities. Towels may or may not be provided, so ask in advance. You then spend the day moving between pools, resting areas and the restaurant at your own pace. The lunch is part of the programme and is usually served at a set time, so check when and mention dietary needs when you book.
What to expect
Thermal pools vary from comfortably warm to hot, and it is wise to start with the cooler ones and limit your time in the hottest to short soaks. Spending too long in hot water can cause dizziness, so drink plenty of water and get out if you feel unwell.
The surroundings are usually gardens or forest, with the sound of water and birds. Some sites offer mud for the skin, and others have a spa for massages and treatments, which may be extra. Expect a peaceful mood, so keep voices low and phones quiet.
Making the most of it
Bring a swimsuit, a towel if not provided, flip-flops, a change of clothes, sunscreen and a refillable water bottle. Avoid alcohol before soaking, as it increases the effects of heat. Arrive early to enjoy the quiet, and plan for a slow evening afterwards. People with heart conditions, high blood pressure or who are pregnant should check with a doctor before using hot pools.
The day combines well with a visit to a waterfall such as Llanos de Cortes or the Rincon de la Vieja park on another day, but resist the urge to pack too much in: the point is to rest.
