How many volcanoes are in Guatemala?
Compare source-specific counts of Holocene volcanoes and older eruptive centres. Understand the counting unit, dates and where Pacaya fits.

How many volcanoes are in Guatemala depends on what the source counts. The Smithsonian's country list shows 20 Holocene volcanoes, checked October 2026. A CONRED article about a climbing project uses 37 in a distinct context. These are not interchangeable totals, and neither number should be published without its definition and date.
In brief: use a named source's count with its counting unit. A volcano record can cover several features, while a climbing list can serve another purpose. Pacaya belongs in the Smithsonian list, but the cones within its complex are not all separate country-list entries.
How many volcanoes are in Guatemala in the Smithsonian list?
The Global Volcanism Program's Guatemala page lists 20 Holocene volcanoes. We checked that country page in October 2026. This is a count in that database. It is not a count of every volcanic hill. It is not a list of every named climb.
The GVP Holocene list covers volcanoes that erupted in about the last 12,000 years. Its records use rules about the evidence. That is a list with a time limit. It does not claim to cover all volcanic ground. Keep that time limit with the total.
The page also sets rules for where a volcano is counted. A volcano on a shared boundary can appear in more than one country's count. Do not add country totals together and assume the result is a count of unique volcanoes worldwide. The rule is part of the method. It matters to the total.
Where the count of 37 appears
CONRED's article of 9 December 2014 about Reto 37 describes a project to climb 37 Guatemalan volcanoes. Pacaya was part of the event described. This shows how the agency used the count for that climbing project. It is not a new count issued today.
The article does not provide a complete modern comparison between that list and GVP's inclusion rules. We therefore do not invent one. Do not assume that the difference means either source counted carelessly. First ask what each list was intended to describe.
| Source-specific figure | What the cited source is doing | Date or check |
|---|---|---|
| 20 | GVP country list of Holocene volcanoes | Checked October 2026 |
| 37 | CONRED account of the Reto 37 climbing project | Published 9 December 2014; checked October 2026 |

The table preserves those contexts. It is not a ranking of the sources or a calculation of missing mountains. We have not expanded it with unsupported claims about every cone in Guatemala. A count can be exact for one method. It may still be the wrong count for another question.
Why the counting unit matters
A volcanic complex can contain several named cones, craters or domes. Counting each feature on its own would produce a distinct result from counting the complex as one record. Before comparing totals, check what the author counts. The word volcano alone may not make that clear.
The Pacaya GVP record illustrates the issue. It has one main volcano record and describes named features within the complex. Finding several feature names does not mean each should be added to the national total. They may already belong to the record being counted.
Nor is every peak name a separate science volcano record. A label can name part of a larger landform. A climbing list may organise destinations in a way useful to climbers. That can be useful without matching the database row for row.
This is why averaging distinct totals does not solve a disagreement. The average would have no clear counting rule. Adding one list's features to another list's complexes can also double-count the same landscape. Keep the source's own units intact.
How many volcanoes are in Guatemala that are active?
“Active” needs a time frame and a definition. It can mean a broad group in geology. It can also mean an eruption seen in a stated period.
An eruption in progress is a more specific question again. Those questions produce distinct lists. Do not use the headline Holocene total as a live activity count.
The GVP country tables separate categories rather than treating them as synonyms. If you quote an activity total, preserve the table's time window and its date. A record of a past eruption does not prove that the same volcano is erupting during your visit. A current monitoring bulletin is a separate source.
Likewise, a volcano not shown as currently erupting should not be labelled safe or open to visitors. Access involves the responsible authorities and the actual route. A country count cannot answer that local question. Keep the database separate from a trip's access instructions.
Where Pacaya fits
Pacaya appears in the Smithsonian's Guatemala Holocene list as one named record. Its broader landscape includes older features and the Mackenney cone. The formation guide explains why a multi-stage complex cannot be reduced to a single birth event. That history also helps explain why counting visible cones is not the same as counting records.
For travel, first settle whether you want to understand the volcano or arrange a walk. A national count gives context. It does not name your entrance. The Pacaya overview connects the place with the main visit choices. A current guide and return plan are still needed for an outing.
Do not turn the count into a list of hikes you can book. Some entries may be relevant to science without being a visit option for your date. We do not create a national destination listing from the country table. The purpose here is to explain the counts and Pacaya's place within them.
A clear way to cite a total
Write the source, scope and date together. For example, give the GVP list's own scope and check date. Do not turn it into a national total without limits. If you use the past climbing-project figure, name it as that. The reader can then see what the number answers.
When two sources disagree, compare their lists and rules before choosing a headline. Check whether one includes older landforms or treats parts of a complex as their own entries. If the method is not supplied, leave that limitation visible. Do not fill it with an assumed explanation.
Avoid copying an old current-activity count into a new paragraph without its date. A page can be newly updated while retaining an older table. The relevant date is the one attached to the data itself. Check that before treating a count as current.
Check the unit before reusing a table
Keep the heading when copying a count into your notes. A total of records is not a total of every named feature within them. If the source changes its scope, a later count may change without a new mountain appearing. Read the method before describing that as a discovery. The number and its definition belong together, even in a short summary.

Verdict: give the definition with the number
For “how many volcanoes are in Guatemala,” give the source with the total. The checked Smithsonian Holocene list and the past Reto 37 account describe distinct scopes. Keep their methods separate and use Pacaya as one example of how complex landscapes are grouped.
