Tabacon offers several ways for you to enjoy their hot springs. You can try just their hot springs for $25, or you can have dinner as well for $45. There is an additional charge for towels and locker rentals. They also have spa services available for added costs. The thing you have to remember is that the spring area closes at 10pm, so you have to plan your time accordingly. There are several pools and falls, each feed with the mineral water and heated by natural hot springs—some pools are hotter than others. This is a great therapeutic place to visit, especially if you had an active day canyoning, horseback riding, hiking, canopy touring, or ATVing. There are numerous trees, plants, and falls surrounding the various pools. The nature and plants are best seen in the morning while the volcano is better seen at night. Some pools are secretly hidden away. Drinks are available at the bar area. One tip is to sit under the falls and allow the hot healing waters to hit your back if you have back pain. I know that some may say this is be a waste of $25, since you may get a similar experience at a free Jacuzzi at your hotel. However, the atmosphere is different and was worth the cost, to me at least. The springs attract a mixed crowd of younger and older people.
Warning: Tabacon Hot Springs lies in a "high-risk zone" which is in the volcanoes path. In 1968, 78 people were killed by an eruption which hit Tabacon. In June 1975, before the spa was built, rock and burning gases passed over the spot. In 1993, pyroclastic flows came dangerously close to it. Potentially deadly avalanches occur within the zone once every 2-3 years.
