Mineral Hot Springs, Pools & Waterfalls

Embedded in scenic patches of rainforest, our hot springs provide our guests with great views of the volcano and a multitude of options. With temperatures ranging from 83 degrees Fahrenheit to 104 degrees Fahrenheit and environments that vary from raging waterfalls to tranquil forest experiences, our guests can find the perfect pool for their mood and the current weather conditions. Tests of our hot mineral springs reveal an ideal natural combination of high bicarbonate and high chlorides with relatively low sulfur content to provide a truly pleasurable soaking experience.

Las Lagunas Pools

Open from 10:00 AM to 10:00 PM

Located at the base of the reception building, this enchanting montage of hot spring lagoons and chlorinated pools hosts our ever popular Las Lagunas Swim-Up Bar where you can enjoy a delicious tropical drink and a great view of the Volcano. In this area you can explore two acres of lush landscaping and an assortment of multi-level sun and shade terraces surrounding twelve pools all with cascading waterfalls. Eight of the pools are fed directly by our hot mineral springs and the other four are chlorinated but heated to comfortable temperatures for those hot, sunny days. These pools range in temperature from 86˚F to 103˚F.

Perdido Springs

Monkey Slide Open from 12:30 PM to 8:00 PM

Perdido Springs (Lost Springs) is an interconnected system of forest trails and seven spring-fed pools located within a forest canyon just a short 100-meter walk from the lowest level of the Las Lagunas pools. At the heart of these flowing pools you will find Los Perdidos Bar (The Lost Ones) and Rancho Perdidos Bar along with our thrilling water flume called the Monkey Slide. These pools range in temperature from 91˚F to 104˚F.

Club Rio Springs

We highly recommend you visit the Hot Springs at Club Rio Adventure Center. They are truly some of the most beautiful spring pools in the world, and most of them border the river, allowing for amazingly scenic views of the flora and fauna of the river canyon. It is a spiritual event just walking through the towering rainforest by the river’s edge and finding flowing hot spring pools around every turn in the trail. You don’t want to miss the crystal blue water of our famous Ojo del Agua (Eye of the Water) spring where you can feel the hot mineral water and bicarbonate bubbles flowing through your toes from the depths of the earth beneath you.

About Our Hot Mineral Springs

Our Hot Mineral Water is captured from natural springs near the river and are pumped up 420 feet (130 meters) to our pools. Each night at closing the pools are drained, cleaned and refilled starting at 6:00 AM. During the hours of operation new hot water continually flows into the system. The water is also circulated through a filtration system in these pools to eliminate some of the precipitated minerals and foreign contaminants.

The therapeutic effects of various minerals have been extensively studied by European balneologists. To be classified as a mineral spring the water needs to contain greater than 1,000 mg/l (PPM) of naturally dissolved solids. Here at the Springs Resort and Spa our water contains over 1,500 mg/l (PPM) of dissolved solidsand has a PH averaging 6.4 so its mineral/chemical composition lends it a slightly acidic nature common to many of the world’s best hot springs. Below is a summary of the effects of each of the minerals found in our hot springs and a comparison with other local hot springs.

Benefits of Bicarbonates (HCO3)- – To qualify as a bicarbonate spring the water must contain at least 250 mg/l of bicarbonate gasses. Ours contains the highest level in the Arenal area (751 mg/l) which is nearly three times the threshold required. Balneologists generally agree that a high bicarbonate level is the most important component of medically therapeutic hot springs. Bicarbonates assist in opening peripheral blood vessels and improving circulation which aids against cardiovascular disease including hypertension and mild atherosclerosis. For these conditions balneologists recommend a water temperature no higher than 100˚F. Bicarbonate waters are also thought to have a positive effect on nervous system imbalances.

Benefits of Sodium (NA+) Natural salts assist with the alleviation of arthritic symptoms, stimulate the body’s lymphatic system and also help to maintain body fluid balance.

Benefits of Calcium (CA++) Calcium strengthens bones to prevent osteoporosis and helps to regulate bodily functions. It is essential to the function of many internal organs such as the heart.

The Springs = 95 mg/l Baldi = 106 mg/l

Benefits of Potassium (K+) This element assists in the normalization of heart rhythms, reduces high blood pressure, helps to eliminate body toxins and promotes healthy skin.

The Springs = 28 mg/l Baldi = 39 mg/l

Benefits of Boron (B) Boron builds muscle mass, increases brain activity and strengthens bones. In addition it is an ophthalmologic irrigant that aids in cleansing your eyes.

The Springs = 7.8 mg/l Baldi = 2.8 mg/l

Benefits of Magnesium (Mg++) Magnesium maintains normal heart rhythms, assists in reducing high blood pressure and aids in eliminating body toxins. It also converts bl
