Arenal Volcano
The months in gold are when the weather, the crowds and the prices work out best.
Arenal is worth visiting if you want to combine volcanic hiking with natural hot springs, though the area is highly commercialized. Go between December and April for the driest weather. Plan to spend two to three days here to cover the main trails and thermal pools.
Access to the best thermal hot springs requires expensive day passes.
The daily figure is an estimate and does not include flights. The exchange rate is real, and it moves once a day, not by the second.
Two to three days is enough to hike the trails and visit the springs.
Most travelers take a shared shuttle or rent a car from San José, which takes about three hours.
You need separate tickets for the national park and the private hot spring resorts.
The best hot springs require expensive day passes, and the volcano peak is often hidden by clouds.
What to expect on the ground
The area around the volcano is heavily developed for tourism. La Fortuna is the nearby hub, filled with hotels, restaurants, and tour agencies. You will not be alone on the trails, and you will hear traffic from the main road while walking some of the lower loops.
The volcano itself is a constant backdrop, but clouds cover the peak for most of the day. Hiking here means walking over old lava flows from the 1968 eruption. The terrain is rocky and uneven, requiring sturdy shoes rather than light sneakers.
The best months to visit
December through April offers the dry season, which gives you the best chance of actually seeing the summit. During these months, the trails are less muddy and outdoor activities are rarely rained out.
However, this is also the peak travel season. Prices for accommodation rise significantly and the popular hot springs get crowded. If you visit outside these months, prepare for heavy afternoon downpours that make the clay trails slick.
Common misconceptions
Many travelers arrive expecting to see red lava flowing down the slopes. The volcano has been quiet for over a decade, so you will only see a green, forested cone and old lava rocks. Climbing to the crater is also strictly forbidden due to safety regulations and toxic gas emissions.
Another mistake is assuming the hot springs are free and open to everyone. While there is a public river where locals swim, the clean, landscaped thermal pools belong to private resorts. You must buy an expensive day pass to access them.
The background
Arenal Volcano (Spanish: Volcán Arenal) is a recently active andesitic stratovolcano in north-western Costa Rica around 90 km (56 mi) northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. The Arenal volcano stands 1,633 metres (5,358 ft) high. It is conically shaped with a crater 140 metres (460 ft) in diameter. Geologically, Arenal is considered a young volcano and it is estimated to be less than 7,500 years old. It is also known as "Pan de Azúcar", "Canaste", "Volcan Costa Rica", "Volcan Río Frío" or "Guatusos Peak". The volcano was dormant for hundreds of years and exhibited two craters at its summit, with minor fumaroles activity, covered by dense vegetation. In 1968 it erupted unexpectedly, destroying the small town of Tabacón. Due to the eruption three more craters were created on the western flanks but only one of them exists today. By duration, Arenal's eruption from 1968 to 2010 is the tenth longest volcanic eruption on Earth since 1750. Since 2010, Arenal has been dormant.
