❓ So.. Can you Swim in Lake Atitlan?

Yes, you can swim in certain areas of Lake Atitlan.

There are a lot of firsthand accounts and travel stories online or that you may hear in your travels about people getting sick or having skin rashes after swimming in Lake Atitlan. This is why a certain level of caution and research is recommended before you swim in the lake.

Note that I personally have swam in the lake and did not get sick.

In general, it is best to avoid swimming around the bigger towns on the lake such as Panajachel and San Pedro.

Smaller towns around the lake farther away from the bigger ones, as well as San Marcos, are generally considered to be safer to go swimming.

San Marcos also has the Cerro Tzankujil Nature Reserve where there is a popular cliff jumping and swimming spot.

⚠️ Another general rule of thumb is to definitely avoid swallowing the water while swimming and keep near the shore away from the boat traffic. The lake is very deep, so never swim farther than you could physically make it back to shore. And try to shower after your dip in the lake.

🚫 Reasons to Avoid Swimming in Lake Atitlan

Series of landslides over the years have caused a lot of pollution and bacteria to enter the lake that haven’t ever been cleaned out properly.

Fertilizer runoff also can add harmful chemicals to the lake’s waters. The other, sad ongoing pollution factor in the lake is from people dumping trash into it. Sigh.. Humans- why must we be like this?!

These few things can cause cyanobacteria, which in general is not harmful to humans but can cause a toxic algae bloom. The last time this happened was in 2009 and 2015. The water will change colors and have a funky smell, so you will now if there is an algae bloom!

To be honest, I didn’t know any of this before jumping into Lake Atitlan and swimming in it February 2023 on my 7 day trip through Guatemala.

But it is so important to be an informed visitor and keep up to date on the current safety of the lake through local guides and reputable sources. NASA is even tracking the health of the lake through an algae forecasting tool.

And I’d be remiss without mentioning Amigos de Atitlan, a nonprofit organization that advocates for safer agriculture practices and aiding the locals in conserving the lake.

πŸ›οΈ Research your accommodations before booking to ensure the place you’re staying at isn’t contributing to the trash and sewage problem in the lake.

🏊🏻 Best Places to Swim in Lake Atitlan

  • Cerro Tzankujil Nature Reserve in San Marcos. This is where I personally swam in the lake as there is a cliff jumping spot here. But you don’t have to cliff jump to get in- you can easily walk down around the rocks and get in that way! The view from this nature reserve can’t be beat.
  • Casa del Mundo Hotel. There are many platforms to get into the lake here. Guests can enjoy swimming in the lake at their leisure, and if you’re not staying here you can get a day pass to enjoy the grounds.
  • Playa del Finca is a lovely black sand beach, but it is more remote and harder to reach. The beach is a 45 minute walk from San Pedro.
  • Playa las Cristalinas is more of a tradational sandy beach, close to San Juan la Laguna. The beach is easy to reach and a short walk away from the road. This kayaking tour can also bring you to this beach from San Pedro!

Where to Stay in Lake Atitlan

  • πŸ“Amigos hotel – This hotel is located in San Pedro La Laguna and where I personally stayed. There are hostel dorm options here as well as private rooms. I stayed in a private room and had a great experience here, though the bars on the street opposite are loud and stay open until the middle of the night. So bring your ear plugs! The hotel provided breakfast and was very affordable.
  • πŸ“Lush Atitlan – This highly rated hotel is located in San Marcos La Laguna, the hippy town on the lake. This was personally my least favorite town but others love it here. Although the town has one of the best views of the lake! Lush Atitlan has amazing, panoramic views.
  • πŸ“Hotel & Restaurante Arca de Noe – This hotel is in the town of Santa Cruz, one of my favorite spots on the lake. The Arca de Noe has a great location right on the shore of the lake making it easy for arrival and exploring the other towns.
  • πŸ“La Casa del Mundo – Of course I’ve got to add in this hotel in to the list. If I go back to Lake Atitlan I will definitely stay here! The view, the decor, everything about this place is magical. And its surprisingly affordable! The only drawback to staying here is that you are a little isolated and your only option for food is the hotel. Just something to keep in mind if you’re someone who prefers a lot of options!
