Hi, readers. Most swimming holes ask you to fight the water a little, kicking and paddling to stay up.

Laguna Cejar does the opposite. You step in, lean back, and the water holds you at the surface with almost no effort on your part.

Why the floating works

The lake sits inside the Salar de Atacama, a salt flat in northern Chile, and its water carries a very high concentration of dissolved salt. That density is what keeps you buoyant. You will float with your shoulders and face above the surface even if you do nothing. The catch is that the salt stings any small cut, so cover scratches before you get in, and keep your head up rather than diving under. The water is also cold, which surprises people who expect a warm desert pool.

Getting there from San Pedro

Laguna Cejar is roughly 20 kilometers south of San Pedro de Atacama, the town most travelers use as a base. There is no public bus that drops you at the gate, so your options are a tour van, a rental car, or a hired driver. The road is graded dirt and fine for a standard car in dry weather. Tours usually run in the afternoon and combine Cejar with the nearby Ojos del Salar, two small freshwater sinkholes, and the Tebinquinche lagoon for sunset. Expect to pay around $30 to $50 USD per person for a shared tour, or closer to $60 to $90 USD if you hire a private driver for a half day.

Ticket prices and timing

Entry to Laguna Cejar is paid at the gate and runs about $25 USD for foreign visitors, with a lower rate for Chilean residents. Bring cash in local currency, since card machines at remote sites in the Atacama can be unreliable. Go in the afternoon, roughly 3 pm onward, when the light softens and the crowds from midday tours thin out. The site closes before dark, and staff enforce a time limit in the water, usually around 20 minutes, so plan your soak accordingly.

What to bring and know

Pack a towel, sandals for the rocky shore, and a full change of clothes, because the salt dries into a stiff film on fabric. There are basic rinse showers on site, but they are cold, so many people wait and shower back at their hotel in San Pedro. Do not shave or open any skin right before you go. The altitude here is around 2,300 meters, so take it slow if you have just arrived, and drink more water than you think you need. Sunscreen matters too: the Atacama sun is harsh and the reflection off the salt flat doubles the exposure.

The whole visit is short, maybe two hours on site, but the floating itself is the kind of thing you remember. Go in the afternoon, bring cash and a change of clothes, and let the water do the work. Next time you swim somewhere and find yourself treading hard to stay up, you will think back to this lake and how little it asked of you.
