The Monterrico turtle release is the best-known sea turtle hatchling release experience in Guatemala — and it is also the one most often described inaccurately in English. This page does the thing no other English page appears to do: it puts the actual CONAP regulation next to the experience visitors report, explains the legal egg-quota system that makes Guatemala’s turtle economy work, and tells you what a rule-compliant visit looks like.
Short version: go September through November (our synthesis — see below), go to the Tortugario Monterrico run by CECON, the Centro de Estudios Conservacionistas of the Universidad de San Carlos (USAC), inside the Reserva Natural de Usos Múltiples Monterrico in Taxisco, Santa Rosa. Expect a late-afternoon release, expect a mandatory conservation talk, and expect — under the written rules — to watch, not to handle a hatchling.

| Best visitor months | September–November, releases starting late August | Our synthesis from nesting + incubation data |
| Nesting peak | August and September; nesting roughly July to late October | ARCAS |
| 2026-27 season | Officially launched by CONAP and allies, August 2026 — no calendar opening date was published | CONAP, Diario de Centro América |
| Typical release time | Law: 17:30 (day-hatched) or 06:00/pre-dawn (night-hatched) | CONAP Normativo Art. 35(1) |
| Group cap | 20 people per scheduled release | CONAP Normativo Art. 35(4) |
| Price | Not currently published — see the price section | own probe, Aug 24 2026 |
The season: when to actually go
The season dates you find online contradict each other because they measure different things. Nesting is one clock; hatching is another, about 45–55 days later.
| What | Window | Source |
|---|---|---|
| Olive ridley (parlama) nesting near Monterrico | Roughly July to late October; solitary nesters year-round | ARCAS |
| Peak nesting | August and September — up to 30 nests per night across ARCAS’s ~10 km of monitored coast | ARCAS |
| Hatching in the hatchery begins | Usually late August | ARCAS |
| Incubation period | ~50 days (CECON); 40–60 days (general); 45–55 days (ARCAS) | USAC news; Guatemala.com; ARCAS |
| CECON Monterrico operating window as reported | August to February | USAC news (2022) |
| Commonly cited visitor season | September to December | Guatemala.com |
| Leatherback (baula) nesting | November–December, only 2–3 nests per year, declining | ARCAS |
| Green turtle nesting | 2–4 nests per year, August–October in recent years | ARCAS |
Our reading: nesting peaks August–September, hatching follows roughly seven weeks later, so September through November is the reliable visitor window, with releases beginning in late August. That sentence is our synthesis of the ARCAS and CECON figures above — it is not a quoted official season.
On the 2026-2027 season: CONAP and partners launched it in August 2026, inaugurating a permanent educational exhibition at the El Paredón tortugario in Sipacate, Escuintla, supported by WWF. Neither CONAP’s announcement nor the state gazette’s coverage published a calendar opening date. So there is no official “opening day” to plan around.
The rules — what the regulation actually says
This is the part almost nobody publishes. Guatemala’s release rules live in CONAP’s Normativo para el Manejo y Conservación de Tortugas Marinas, Documento técnico No. 36-2017, Chapter X. Its legal footing runs back to Constitutional articles 64, 97 and 119(c), the Ley de Áreas Protegidas (Decreto 4-89) and its regulation (Acuerdo Gubernativo 759-90), plus the CIT, CITES and CBD conventions.
| Rule | Article |
|---|---|
| Hatchlings born at night are released at 06:00 or before sunrise | Art. 35(1) |
| Hatchlings born in the day are kept cool, shaded, on damp sand, and released at 17:30 | Art. 35(1) |
| Hatchlings must not be kept in tanks or basins, and not kept in public view | Art. 35(1) |
| Hatchlings must not be handed to visitors — visitors may only observe | Art. 35(2) |
| Flash devices are prohibited | Art. 35(3) |
| Maximum 20 people per scheduled release | Art. 35(4) |
| A conservation talk is obligatory before the release | Art. 36(1) |
| Manipulation of hatchlings, juveniles and adults is to be avoided at all times | Art. 36(3) |
And what visitors describe
Now the tension, presented plainly and with no accusation attached to any operator. USAC’s own news service, in an October 2022 piece about Monterrico, describes sponsors receiving their hatchling in a jícara (a gourd bowl) and releasing it themselves from behind a rope-and-post line on the beach, at a sponsorship price of Q10 per hatchling, with weekday releases at 17:00 and weekend releases at 16:00 and 17:00.
That description and Article 35(2) do not fit together. We cannot resolve the gap from public sources, and we are not going to guess. Possible explanations include a practice that changed after 2017, uneven enforcement, or a jícara that is set on the sand rather than handed over. The honest statement is: the rules on paper are stricter than most visitor accounts describe.
What a rule-compliant visit looks like
- You arrive for a scheduled release, not an improvised one.
- You attend the conservation talk first — it is mandatory under Art. 36(1), not an upsell.
- You stay behind the marked line and observe. If you are offered a hatchling to carry, you now know what the regulation says; declining is always safe and always legal.
- No flash. Ever. Light disorients hatchlings, and flash is separately prohibited by Art. 35(3).
- No touching the hatchlings on their way to the water. They must reach the sea unaided — partly because that crawl is how they imprint on the birth beach, and partly because visitor hands carry sunscreen and repellent onto very sensitive skin.
- Groups are capped at 20. A visibly larger crowd is a sign the release is not being run to the Normativo.
The quota system: why selling turtle eggs is legal here
Foreign visitors are often startled to learn that selling parlama eggs is legal in Guatemala. It is not a poaching loophole; it is a receipted, quota-based system, and understanding it changes how you read the whole scene.
| Element | How it works |
|---|---|
| Who collects | A parlamero — an individual registered and authorised by CONAP who collects parlama eggs, delivers the conservation quota, and may commercialise the rest for subsistence purposes (Art. 2(d)) |
| The quota | 20% of the eggs collected from each parlama nest, delivered to an authorised tortugario |
| Where the 20% is fixed | CONAP Council Resolución No. 01-21-2012, cited in Art. 20(c). The Normativo itself does not fix a number — Art. 23 gives CONAP the power to set and re-evaluate it on scientific and socioeconomic criteria |
| Species covered | Parlama / olive ridley (Lepidochelys olivacea) only. ARCAS states harvest of all other species is prohibited |
| The receipt | A Comprobante de Cuota de Conservación, issued by the hatchery — the legal document that authorises transport and sale of the remaining eggs (Art. 2(f), Art. 24) |
| Receipt design | Three removable sections sharing one correlative number, with a CONAP watermark logo on each dividing line (Art. 28) |
| Receipt validity | 24 hours. Eggs shown with an expired comprobante are treated as illegal in origin (Art. 29) |
| Season duty | At the start of the season the tortugario must convene the parlameros for a talk on the quota and its benefits (Art. 16) |
| How old | The collector-donation system has been in place since the 1980s |
| Scale in 2026 | More than 30 hatcheries registered with CONAP |
The framing that fits the evidence: Guatemala permits subsistence sale of olive ridley eggs precisely in exchange for a guaranteed conservation share, with a 24-hour paper trail. ARCAS — a conservation NGO, not a government body — says it worked with CONAP and the Humane Society to allow a controlled harvest while enforcing a total ban on other species, and that its crawl-count data show the Guatemalan olive ridley population steadily increasing.
Where the money goes, and what it costs
The money flow is the strongest sourced answer on this page. At the CECON tortugario, according to USAC’s news service quoting CECON park ranger César Grijalva, apadrinamiento (sponsorship) money is used to buy parlama eggs directly from collectors — money that converts into eggs which would otherwise be sold for consumption. CECON also receives eggs through the legal route: an agreement with collectors for donation of 20% of the nest, supervised by CONAP and CECON.
On price, we are deliberately publishing less than other pages do.
| Operator | Figure | Year | Status |
|---|---|---|---|
| CECON Monterrico (USAC) | Q10 apadrinamiento per hatchling | 2022 | Historic reference point only — not a current price |
| AGHN, Taxisco (different operator, aldea Madre Vieja, Km 137.5) | Q25 general admission (includes release, parking, Museo del Mar); Q100 nest sponsorship | 2025 | That operator’s published prices — do not apply to Monterrico |
| Tortugarios generally | Q15–Q20 symbolic contribution per person | 2025 | Generic consumer coverage |
No current price for the CECON Monterrico tortugario is published anywhere we can verify. When we probed on August 24, 2026, cecon.usac.edu.gt returned a server error on every path and the CECON CMS host did not resolve in DNS — there is currently no live official CECON page at all. The only traceable figure is the Q10 from 2022, and four years is too long to present it as current.
Be careful with search results here: web summaries have been returning Q25 / Q100 as if it were the Monterrico price. Reading the source article shows those are AGHN’s prices in Taxisco — a different operator in a different village. Bring cash, and ask at the gate.
Practical: the visit itself
- Timing. Late afternoon is the norm. The law specifies 17:30 for day-hatched and 06:00 or pre-dawn for night-hatched hatchlings; 2022 reporting put Monterrico’s releases at 17:00 on weekdays, 16:00 and 17:00 at weekends. Arrive early enough for the mandatory talk.
- Mechanics. Night-born hatchlings are reported to be released immediately; day-born ones are held in a dark room and released in the afternoon. Participants stand behind a rope-and-post line.
- What to bring. Cash in small denominations (no verified current price to budget against), a camera with flash disabled, water, and shoes you do not mind getting sandy — Monterrico’s beach is black volcanic sand.
- What else is on site. The reserve is roughly 65% water bodies, part of the Canal de Chiquimulilla estuarine system, with 110+ resident and migratory bird species. The tortugario also keeps green iguana, caimán, and land and sea turtles for environmental education, reintroduction and repopulation.
- Weather: we did not verify Pacific-coast temperature data for this page, so we are not printing heat figures. Assume hot and humid coastal conditions and plan accordingly.
Ethics: how to be a good visitor
Sea turtle conservation here runs on visitor money, so the goal is not to avoid the experience — it is to do it correctly.
- Observe rather than handle. It is what the regulation requires, and handling is what best practice avoids.
- Never midday. ARCAS’s own best practice is release at night or early/late in the day — never midday, because of predators and dehydration — above the high tide line, letting hatchlings crawl unhindered so they imprint, and varying release points so offshore predators do not learn to wait.
- Keep expectations honest. Between 1 in 1,000 and 1 in 10,000 hatchlings is reported to reach adulthood. A nest holds 60–140 eggs, averaging 92.
- Context. Five of the world’s seven sea turtle species occur in Guatemalan waters — parlama, carey, baula, verde and caguama — across 255 km of Pacific and 148 km of Caribbean coastline. The main threats are pollution, climate change, habitat loss, incidental capture and egg over-harvest.
We found no evidence of a turtle festival running in Monterrico in 2024, 2025 or 2026. Editions of a Festival de la Tortuga are traceable to 2009, 2010 and 2011. If you see a 2026 “Tortuga Festival” in search results, check the location — a large US music festival of a similar name dominates those queries. The verified 2026 event is CONAP’s season launch at El Paredón, not a Monterrico festival.

Where to stay
Because releases run at dawn or late afternoon, most visitors overnight in Monterrico rather than trying to do it as a same-day trip from the capital.

Bottom line
Go between September and November, base yourself in Monterrico overnight, arrive in time for the mandatory conservation talk, and go in expecting to watch a release rather than perform one. Bring cash because no current price is published. And if you take one idea home, make it the comprobante: a three-part, watermarked, 24-hour receipt is what stands between a legal subsistence egg sale and an illegal one on this coast.
