Can You Swim In Lake Atitlan, Guatemala? Water Quality, Sewage & Safety

You’d think Lake Atitlan would be the perfect place for a dip. But you’ll quickly hear stories of pollution, sewage, and people getting sick. So, can you really swim in Lake Atitlan?

You can’t miss visiting Lake Atitlan when traveling in Guatemala. It’s a beautiful spot, perfect to chill out a little. Though when it comes to swimming, not all areas of the lake are equal due to boat traffic and untreated wastewater.

You’ll see photos of people cliff jumping in San Marcos or straight in from the piers, yet the closer you get, the more mixed the advice becomes about whether it’s actually safe.

Did I get sick traveling in Guatemala? Yup. Was it from swimming in Lake Atitlan? No, not even after spending a week there visiting multiple towns. Instead, my downfall was a random McDonald’s stop, traveling from Flores to Semuc Champey.

Technically, yes, you can swim in Lake Atitlan, but it depends a lot on the location. There are also a few other things worth knowing as well, like conditions can change depending on the season and heavy rains.

Safest swim spots: El Jaibalito, Cerro Tzankujil Nature Reserve, and Playa La Finca.

Where Are The Best Spots To Swim In Lake Atitlan?

Let’s start with the main question: where can you actually swim around the lake? First, we will get into the location or villages where it’s okay to swim, and secondly, the rules you should follow to keep safe.

What Villages Should You Avoid Swimming?

Swimming near larger towns and busy piers is not recommended, neither by your doctor nor by me. These areas have a lot more pollution, runoff, and heavy boat traffic, making the water quite questionable.

Basically, piers are a big no-no for two reasons:

• Boats can’t easily see swimmers in the water when traveling between towns on Lake Atitlan
• Fuel and diesel hang around near the docks

These boats travel pretty fast around the lake. It can be wavy, and depending on the weather, the visibility can be limited. All this is a dangerous combo for swimmers near boats.

You’ll need to think twice if you’re considering swimming at Panajachel and San Pedro La Laguna, since there’s a higher risk of contamination, and definitely not next to the ferry routes and docks. You’ll still see people swimming here, but as a result, they’re at greater risk.

What about Santa Cruz La Laguna? (My Experience)

Okay, Santa Cruz La Laguna is a bit of a grey area. While certain parts of the village are pretty close to the dock and boat traffic, there are some quieter swimming spots.

During my stay in Santa Cruz at Free Cerveza, I heard plenty of stories from travelers about them getting sick after swimming in big towns around piers, which was enough to put me off going for a dip in those areas.

Instead, I opted for kayaking, which was the smart decision since there were dead fish just floating on the surface. I asked a staff member at the hostel and was told it was because of pollution from a nearby river and that it’s not usually like this.

Safer Places To Swim

Generally, quieter villages and the areas away from piers are your best bet. You’ll find cleaner water here and less traffic.

Some of the best places to swim in Lake Atitlan:

• El Jaibalito: quieter village, limited boat traffic
• Santa Cruz La Laguna: swimmable away from the docks
• Cerro Tzankujil Nature Reserve: a nature reserve with cliff jumping & is the best thing to do in San Marcos
• Playa La Finca: no boat traffic & away from towns

Sticking to quieter areas and away from the main ferry routes significantly reduces your risks.

Why Water Quality Varies Around Lake Atitlan

Water quality around Lake Atitlan isn’t the same everywhere. This is exactly why advice on swimming spots can be all over the place.

It can be negatively affected by population density, wastewater, rainfall, and what’s around that could flow into the lake.

During the rainy season, heavy storms can increase runoff from nearby villages and rivers, temporarily affecting water quality in certain areas of the lake.

Algae Bloom Around Lake Atitlán

Algae blooms (cyanobacteria) first appeared at Lake Atitlan in 2009, covering over half of the lake. Even nowadays, it can still cover massive areas of the lake. When it’s there, you’ll notice a thin green film on the water instead of the standard deep blue colour.

The main cause is excess nutrients from fertilisers and untreated sewage entering the lake after heavy rain. On top of this, rubbish dumping on the shoreline definitely hasn’t helped the issue either.

Now, algae blooms aren’t unique to just Lake Atitlan, they happen worldwide. Seriously, I grew up hearing all about this in the lakeside town of Taupo in New Zealand.

While there have been ongoing efforts over the past decade to improve waste management and water quality here, it’s a slow and costly process.

If you do see water with this green algae film, avoid swimming there. They aren’t present all year round and usually occur after heavy rains, so conditions can change quite often.

The Issue Of Sewage

Now, for the subject of whether raw sewage goes into Lake Atitlan or if it’s simply grey water. Unfortunately, it’s pretty normal to see grey water trickling its way down the streets towards the shoreline, which isn’t great.

Amigos del Lago de Atitlan has raised concerns that untreated sewage is still reaching the water, but figuring out the exact amount is more complicated.

There are wastewater treatment facilities around the lake, but the post-treated water is reported as still being quite cloudy and foamy. This is why swimming around populated towns or drains carries a higher risk of getting sick.

There are talks about expanding treatment infrastructure, though concerns over funding and charging locals to use them have put those ideas on hold.

What Kind Of Sick May I Get?

Now, there are definitely some health risks with swimming in Lake Atitlan, and it’s worth knowing about them.

In 2009, Global Press Journal reported cyanobacteria in the lake, which can affect the skin and, if ingested, cause stomach issues.

That said, not everyone who swims in Lake Atitlan actually gets sick. You’ll be happy to know many people don’t!

You’re more likely to get sick swimming in busy towns, by docks, or after heavy rainfall. A safer bet is quiet areas known for clean water. Also, don’t put your head under as it’s not worth risking the gastrointestinal issues, speaking from experience after tubing in Laos.

Rashes are one of the more common issues here. And while they’re usually pretty mild, your best bet is to do a little rinse off after swimming.

Lake Atitlan Water Temperature

Luckily, the water here stays at a consistent temperature all year round of 21°C / 70°F.

Honestly, I never used to think too much about water temp. I’d dip a foot in, and if it didn’t send me into shock, we’re good. But after diving in Belize and Honduras, where the water sits closer to 28°C / 82°F, it definitely feels on the chilly side here.

Nevertheless, if you’re brave enough while traveling Lake Atitlan, you can certainly plunge in for a bit of a swim. But this is a high altitude lake, so I wouldn’t say you’ll be frolicking in the waters all day.

What To Know Before You Go Swimming

While there are no official rules about swimming here in Lake Atitlan, there are some more common-sense things to know to stay safe.

Here’s how to reduce your risk:

• Avoid piers and ferry routes (boat traffic & runoff)
• Stick to quieter villages and protected areas
• Don’t swim after heavy rain (increased contamination risk)
• Keep your head above water and don’t swallow it
• Avoid areas with hydrilla (pashte) as it’s possible to get entangled
• Rinse off after swimming

What’s Being Done To Fix It?

Now, there’s no denying Lake Atitlan has some pollution issues. Though thankfully, they aren’t being ignored.

This lake is super important to Indigenous communities who live here, and they want to look after it for the future.

Thankfully, there are local conservation efforts going on to try improve waste management and water quality. This includes community cleanups, educational campaigns, and wastewater treatment upgrades. And even though this progress is slow and complicated, it’s happening.

For now, the most practical things you can do while traveling there are to not litter, support eco-conscious accommodation, and reduce plastic use.

Where to Stay In Lake Atitlan

There are plenty of villages dotted around the lake where you can stay. Each one has a slightly different vibe, so you’re best to book a couple of spots and then check out the rest by boat, which is the main transport method.
