A Volcano You Can Drive To… If the Clouds Cooperate
Towering over the Central Valley is Irazu Volcano, the tallest volcano in all of Costa Rica. This active volcano is located in the Cartago Province, just about an hour from the city of Cartago, and an hour and a half from the city of San Jose.
At an elevation of 11,260 feet, visiting Irazu Volcano is an experience unto itself. Located high above the clouds, the temperature here is cold, the wind is strong, and the landscape looks otherworldly. A visit to this iconic crater volcano is almost an absolute must on any Costa Rican vacation.
But, in order to pull off the experience, there are some tips and tricks to keep in mind.
Where Is Volcán Irazú?
Irazu Volcano is part of the Cordillera Central mountain range. The volcano is located within the Cartago Province, and while it might not look too far from San Jose on a map, the road conditions and elevation changes make the drive around one and a half hours, depending on traffic.
To reach the entrance to the national park, you’ll climb north up the mountainside from Cartago City along the winding Ruta 219. As you climb up through the mountains, you’ll feel the temperature drop. To get the most out of your time here, it’s best to visit as early in the day as possible, as the afternoon brings clouds and often rain.
What to See at Irazú Volcano National Park
Irazu Volcano National Park features the principal crater, Diego de la Haya crater, as well as a mile of hiking trails.
1. Crater Principal
The principal or main crater is definitely the show stopper, and the reason why people ascend to the top of the mountain every day. It’s an impressive 3,444 ft in diameter, 984 ft deep. The landscape surrounding this active crater volcano has a Moon-like feel, with shades of gray painting the crater from old volcanic flows and activity.
The last eruption from the active main crater occurred on December 8, 1994, and lasted for just one day, while some previous eruptions lasted for two to three days. Be sure to check with SINAC about volcanic activity before you book your national park entrance tickets.
2. Diego de la Haya Crater
Just a short walk on the paved path from the main crater is Diego de la Haya Crater. This is a smaller, inactive crater, still impressive and worth visiting once you’re in the park. Diego de la Haya and the main crater can have water from rainfall, creating mineral lakes, often exhibiting bright colors, depending on the time of year and weather.
3. Playa Hermosa
Not to be confused with the popular Guanacaste beach by the same name, this Playa Hermosa is a barran, ash-laden expanse just behind the main crater. Nothing grows here due to the conditions, and walking across this expanse of land gives an eerie feel.
When to Visit Irazú & Weather Tips
Seasonality & Weather at Irazú
The weather doesn’t change much at the top of this mountain, with daily average temperatures ranging between 43 to 48 F. The rainy season is from May to November with the heaviest fog and often wet conditions.
The best time to see the craters and the views is during the dry season, December through April, in the early morning hours.
Again, there is no guarantee of what the weather will be like at this high, desolate location, so pack layers, prepare for sun or rain, and remember your sense of adventure.
What Time of Day to Visit the Volcano
The earlier the better when visiting Irazu Volcano, as the clouds tend to roll in by late morning, often obscuring the view into the craters. It’s hard to know what the weather will be like so high up, but it’s best to arrive as early as possible, and if the clouds are already present, hang around for a while to see if they clear.
You’ll enjoy the views into the craters, as well as the views of the gorgeous surrounding area, when the conditions are right. Thanks to the central location and the high heights, if you’re very lucky, on a clear day, you can see both the Pacific Ocean and the Caribbean Sea. If you do get to see both coasts from Irazu, consider yourself extremely lucky, as these perfect conditions are super rare.
Entrance Fees, Hours & Reservations
The following information is to enter the Sector Crater side of Irazu Volcano National Park. There is another entrance, Sector Prusia, which has more trails, but doesn’t have direct access to the main crater.
Tickets are required to enter either section and must be purchased beforehand using the SINAC official website. Irazu Volcano is one of the most popular national parks in Costa Rica, and being so close to San Jose, it sees many visitors daily. Be sure to book your reservations with plenty of time to avoid complications.
Entrance Fees & Timing
When you purchase your ticket through SINAC, you will select your entrance time, as well as the date. This limits the number of people who can be in the park at any given hour. Ideally, you’ll want to visit early in the morning, with the first entrance time at 8 AM.
There are 150 tickets sold for each hour that the park is open, from 8 AM to 2 PM. The park officially closes at 3:30 PM each afternoon.
The cost for non-resident adults is $15, and for non-resident children is $5. Costa Rica nationals and residents pay 1,000 colones for adults, 500 colones for children. There is also a 2,000 colones fee to park.
Hours
The Irazu Volcano National Park is open every day from 8 AM to 3:30 PM every day, including holidays. Again, this park is very popular with international and national tourists, as well as school and tour groups, so plan accordingly.
Irazú vs Poás Volcano: Which Should You Visit?
During your Costa Rican vacation, you may be faced with the choice of which volcano to visit. What a problem, right?
If you only have time to visit one crater volcano while you’re in Costa Rica–let’s not even worry about Arenal and Turrialba right now–here’s some helpful info to help you decide between Irazu Volcano and Poas Volcano.
Similarities
- Both Poas and Irazu are active crater volcanoes, located within the Greater Metropolitan Area.
- Poas is about an hour and a half drive from San Jose, and so is Irazu.
- Both can be accessed without a 4×4 vehicle and have parking relatively close to the crater viewpoints, so not much hiking is required.
- Both are quite cold, with Poas at 8,858 feet and Irazu at 11,260 feet, with Irazu being considerably higher and colder. Bring a jacket, no matter which you pick!
- It’s best to visit both Poas and Irazu early in the morning, before the clouds roll in.
Differences
- Poas is located in Alajuela Province, north and a bit west of San Jose; Irazu is located northeast of Cartago, on the other side of San Jose.
- Poas is one of the most popular national parks in all of Costa Rica, so there tend to be more people here on a day-to-day basis. Irazu is very popular but has less foot traffic than Poas.
- Poas has a lusher backdrop, whereas Irazu is like being on the moon, with very few plants at that elevation due to the constant cold and wind.
- While both volcanoes are active, Poas is more visible with its activity. Sometimes you see gas clouds rising up out of the crater at Poas. Irazu is active, but less visibly so.
- The surrounding views of Irazu are more expansive and impressive, whereas Poas tends to have a more dramatic view of the volcano itself (when the fog and gas clouds allow).
Plan Your Trip to Irazú, Costa Rica
How to Get to Irazú
To reach the Sector Crater entrance to Irazu Volcano National Park, you’ll take the Ruta 219, north from the city of Cartago. This is a secondary highway, with lots of twists and turns, so be mindful as you climb up towards the mountain.
What to Bring & Practical Tips
That Sector Crate entrance is quite well-established with amenities such as bathrooms, a cafeteria, and display maps. The path to the main crater and Diego de la Haya is paved and wheelchair accessible.
Because the temperature is usually down in the 40s F (5 to 10 C) be sure to have layers to put on. It can also be quite windy and wet, so rain gear is a good idea, though you’ll also want a hat, sunglasses, and sunscreen in case you are there on a sunny day.
Bring plenty of drinking water and a snack. While there is a simple cafeteria, it doesn’t offer much, and it’s best to come prepared… especially if you’re visiting on a crowded day.
Wear comfortable shoes for walking. Watch out for raccoons and pizotes who will try to steal your snacks while you’re eating. Remember, this is Costa Rica!
Keep an open mind. Because you are visiting an active volcano, listen to the advice of the park rangers to stay safe. Follow all signs and do not cross the guardrails. If you don’t get to see the craters because of bad weather, there are no refunds.
What Else to Do Near Irazú Volcano
There isn’t much else to see or do in close proximity to Irazu Volcano, because well, it is an active volcano. But along Ruta 219 you’ll pass by the Sanatoria Carlos Duran, an old tuberculosis ward with a fascinating and spooky history.
The city of Cartago features many sites to check out, and just 50 minutes from Irazu it’s a great addition to a day trip from San Jose. Or head down to Orosi Valley, soak in some hot springs, and enjoy the quieter side of mountain living.
