Irazu volcano National Park is one of the most popular natural attractions in Costa Rica. Because it’s so easy to visit Irazu volcano as you can drive all the way up to the summit, many visitors flock to the highest volcano in Costa Rica for a day trip. During a visit to the impressive 3,432 meters high Irazu volcano, you can view the craters from above and walk around along the crater ridge to several viewpoints. The total time for visiting Irazu volcano shouldn’t be longer than 1 hour because there’s not more to see than the craters. The walk from the parking lot to the crater is also just a few minutes along a paved path, so it’s a great activity for every age! However there are a few things you need to prepare before visiting Irazu volcano. One of them is buying the entrance tickets online. In this blog post I share everything you need to know about visiting Irazu volcano National Park and some interesting facts about Mount Irazu! 

How to get to Irazu volcano Costa Rica

The Irazu Volcano location is 55 kilometers (34 miles) east of San Jose in the Cartago province. Just like Poás volcano National Park in Alajuela, the way up to Irazú volcano is an easy drive on paved roads. The best way to explore Costa Rica is with a rental car. However, if you’re traveling on a budget, then there is an option with the public bus that leaves from downtown San Jose every day at 8AM. It takes about 2 hours and arrives at Irazu Volcano between 10 AM and 10.30 AM. The bus departs from Irazu back to San Jose at 12:30 PM and will cost about $2 each way. 

The drive up to Irazu Volcano is beautiful as you will pass many farmlands with amazing views. Below some of the most beautiful moments we captured along the way up to Mount Irazu.

After presenting your tickets at the gate you are almost at the main parking area where the short trail to the crater sector of the National Park starts. You get directly at the level of Irazu’s craters which means there is no big hike involved to get to the crater ridge of Irazu. Just a few minutes of walking along a paved path.

Best time to visit Irazu volcano Costa Rica

Considering moment of the day, the best time to visit Irazu volcano is early in the morning. As with every volcano, it is very common that the crater gets wrapped into the clouds as the morning passes. So try to be at the entrance gate as early as possible. We went to Volcán Irazú in March and arrived at the entrance at 8 AM and had beautiful clear views at the crater. There was a beautiful low deck of clouds which really made us feel ‘on top of the world’.

The best season to visit Irazu volcano is in the dry season that goes from December to April. During these months you will have the highest chance of clear views. When rainy season arrives from May to November there is more chance of fog at the crater which makes visibility harder. However the weather is very variable on 3,432 meters height and the clouds can pass. So if you have some patience, wait for some time when it’s cloudy because the clouds may pass.

Irazu volcano facts

Irazú is a stratovolcano formed by lava and pyroclastic flows and has five distinct craters. Irazu is the tallest volcano in Costa Rica at 3,432 meters height (11,260 feet, more than 2 miles) above sea level. The currently hyperactive Turrialba volcano is just a bit smaller at 3,340 meters and is only 12km away from Irazu.

With Irazu being an active volcano, it means there is still seismic activity existing. The first Irazu volcano eruption was reported in the years around 1723. The last volcanic activity was in 1994 when there was a big explosion of steam, rocks and volcanic bombs. This occurs when water is heated by magma. No noticeable volcanic activity has occurred since the 90s so Irazu volcano is safe to visit nowadays being a dormant volcano. Scientists in Costa Rica currently give Irazu a level 1 out of 5 for activity which means it is safe to visit.

The Irazu volcano National Park was created in 1955. But not the whole area is open to the public. The park has a size of 2,300 hectares (5,705 acres) and the public can visit only the main craters.

What to expect when visiting Irazu volcano

Once you set off to the crater area of Mount Irazu, it’s only a few minutes of walking. An easy, paved trail leads from the information center to the first lookout point over the craters.The area of Irazu volcano National Park looks like a moonscape. The vast grey rocky terrain with beautiful textures that show the volcanic activity is so impressive to see. When the sun reflects the colours inside the crater you can really see the nerves and different colours. Very interesting to see and capture with your camera!

The National Park’s landscape contains montane forest, including primary, secondary and cloud forests. There is not much wildlife in this harsh environment, however a few inhabitants such as coatis, coyotes, armadillos, tiger cats, squirrels, foxes, weasels and some species of birds live in the National Park.

The craters of Irazu volcano

Irazu volcano has five distinct craters but you can’t see all of them. The two craters that you can see when visiting Irazu National Park are the main crater and the Diego de la Haya crater which you will see first on your right hand side. Both craters had a beautiful emerald turquoise coloured lake, but unfortunately both Irazu crater lakes dried up. Some people say the lakes might return after heavy rainfall which was the case in 2016. However because of many cracks in the crater wall, the water disappears again.

Playa Hermosa 

Playa Hermosa is the flat and plain dark sand area between the craters. If you walk along the wooden fence you will eventually get to the end of this part of the park. To get back to the parking you will have to walk the same way back as you came. 

If it’s a clear day, then you definitely have to go to the highest viewpoint which you can reach with your car. More about that in the next paragraph. 

Highest viewpoint on Irazu crater 

The final spot you have to check out on a clear day is the highest viewpoint on the Irazu crater. You can get here with your rental, or by foot. Turn left on the dirt road right before you go down the hill towards the parking lot of the National Park. This viewpoint is at 3,500 meters (11000 feet) and will give you an incredible view over Irazu. Here you can take some really cool pictures as well with the impressive craters behind you.
