The two hikes are not variations of one outing. Pacaya is a national park south of Guatemala City, reached in an afternoon. Acatenango is a municipal park on the far side of Antigua, and the overnight climb there is essentially a front-row seat for a different, more active volcano: Fuego. Your choice depends more on whether Fuego is behaving than on which trail is harder.

Sources for the table: CONAP's pages for Pacaya and Acatenango, and INGUAT's guides to Pacaya and Acatenango.

Pacaya's height is given differently by each source because the mountain keeps changing. CONAP lists 2,500 m and calls the figure variable because of eruptions; INGUAT gives about 2,552 m; and the Smithsonian's Global Volcanism Program lists 2,569 m. The programme describes frequent Strombolian eruptions from the Mackenney cone since 1961, with a major eruptive period from February to May 2021.

Is Acatenango open right now?

This is the first thing to check, and it changes with Fuego. The Global Volcanism Program places Acatenango about 15 km southwest of Antigua, paired with Fuego immediately to its south. Acatenango itself last erupted in 1972. The view from its camp exists because Fuego is active, and so does the risk.

On 4 August 2026, CONRED, Guatemala's disaster-reduction agency, reported that access to Acatenango was restricted because of increased Fuego activity under an institutional orange alert. National Civil Police officers were stationed at the entrance to prevent tourists from climbing. We searched CONRED's site on 27 September 2026 and did not find a notice lifting the restriction.

Fuego remained active after that. CONRED's 8 September bulletin reported 5 to 8 weak and moderate explosions per hour and ash columns reaching 4,800 m. Its 1 September bulletin advised against staying on the meseta because of possible ballistic fallout, and described Pacaya over the same night as degassing from the Mackenney crater.

Who charges what, and why the money goes to different places

The two volcanoes sit in different kinds of protected areas, which is why they are paid for differently.

Pacaya is a national park. CONAP names the Instituto Nacional de Bosques (INAB) as its administrator, and an INAB bulletin from October 2025 describes the arrangement as co-administration. INAB reported restoring 3.6 hectares with 5,000 native plants in 2024, working with the Municipality of San Vicente Pacaya and tourism service providers. CONAP lists hours of 7:00 to 18:00 every day.

We could not load the park's own website. The most recent fee figures we found are from a park announcement reported by Guatemala.com: Q100 for international visitors, Q30 for Guatemalans and Q10 for Guatemalan students with ID, from 25 August 2021. The Central America Tourism Agency's Pacaya page still shows Q50 for foreigners, which appears to be an older rate. Carry at least Q100 per person for the gate.

Acatenango is a municipal regional park. CONAP lists the Municipality of Acatenango as administrator. The municipality's own page sets fees of Q100 for foreigners, Q25 for Guatemalans and Q10 for national students, with local residents free. You pay at a Banrural branch into the municipal treasury account, then show the receipt and your passport at the entrance to get a wristband. The municipality says 25% of the income funds development projects in Aldea La Soledad, the village at the trailhead.

Altitude, cold and time: what each hike asks of you

Pacaya is short but not trivial. INGUAT describes a 1.5 to 2 hour ascent over solidified lava fields and ground where fumaroles release heat, on uneven volcanic rock. It recommends boots or trainers with grip, a light jacket, water, sun cream and cash for horses or snacks, plus a headlamp if you hike at sunset. CONAP estimates about an hour by road from Guatemala City via the CA-9 south, turning off at kilometre 37 toward San Vicente Pacaya. INGUAT allows 1.5 to 2 hours from either the capital or Antigua, so plan on the longer figure in traffic.

Acatenango is a mountain night. INGUAT rates it moderate to high difficulty, requiring good fitness but no technical climbing. Daytime temperatures run from 10°C to 18°C, but the camp and summit can reach around 0°C or lower, so thermal layers, gloves, a hat and a windproof jacket are part of the kit. The FCDO warns that local tour organisers tend to underestimate the risks, that deaths have occurred and that there is no mountain rescue service. INGUAT recommends November to April, the dry season, because rain from May to October can make the ascent harder and reduce visibility.

Getting there follows different roads. INGUAT describes Acatenango as relatively accessible from Antigua. CONAP's route from Guatemala City runs west on the CA-1 to kilometre 50 at Chimaltenango, south to Parramos, and then 19 km on to La Soledad: about two hours in total.

Which volcano should you choose?

Choose Pacaya if you have one free day from Guatemala City, are travelling with a mixed-fitness group, or have just arrived and are not ready for nearly 4,000 m. It is also the fallback when Acatenango is closed.

Choose Acatenango if you have two days, gear for sub-zero nights and a clear access status on the day, and seeing Fuego's eruptions at night is the reason you came. If you are basing yourself in Antigua for this, our guide to why Antigua's ruins still stand covers the town itself.

For either, the US State Department advises US citizens not to hike trails or volcanoes without a qualified local guide, warning that robberies can happen and that help can be hard to get. The UK FCDO, updated 13 August 2026, tells British travellers to check the Guatemalan meteorological office (INSIVUMEH) and CONRED for access, restrictions and recommendations before climbing. Save INGUAT's Asistur tourist assistance number, 1500, which it staffs 24 hours a day.
