--- title: "Laguna Cejar: Floating in the Atacama's Salt Lagoon" date: 2026-10-08 canonical: https://tours-atacama.com/salar-de-atacama-lagoons-guide/laguna-cejar-floating-guide/ --- A **laguna cejar tour** takes you to the one lagoon near San Pedro de Atacama where swimming effort basically stops mattering. The water here carries so much dissolved salt that you lie back and it holds you up on its own, the same principle behind floating in the Dead Sea, and that sensation is the entire reason most visitors book this specific half-day trip. I will explain why the salt works the way it does, what to actually bring, and how this half-day recreational swim differs in intent from the longer, scenic lagoon circuit further into the altiplano. If you are still deciding where this fits against [every San Pedro de Atacama tour on price and altitude](/), I think this is one of the easier, lower altitude bookings on the whole list. ## Why Does the Water Let You Float So Easily? Laguna Cejar sits inside the Salar de Atacama, Chile's largest salt flat, and its water holds an unusually high concentration of dissolved salt, dense enough that your body's natural buoyancy does nearly all the work. You genuinely do not need to be a strong swimmer here, since the effort of staying afloat is mostly removed from the equation. **My honest take:** this is one of the few times a travel comparison to the Dead Sea actually holds up rather than being marketing shorthand. I would go in expecting the sensation to feel strange at first, almost like the water is pushing back, and then settle into something genuinely relaxing once you stop trying to swim the normal way. ## What Makes This Different From the Full-Day Lagoon Combo? The intent is completely different, even though both trips visit lagoons inside the Salar de Atacama. This **laguna cejar tour** is a half-day recreational swim built entirely around floating, while the [Salar de Atacama and Altiplanic Lagoons combo](/salar-de-atacama-lagoons-guide/) is a longer, higher altitude scenic circuit covering Piedras Rojas, two highland lagoons, and the Chaxa flamingo reserve, with no swimming involved at all. I would not pick one over the other. **My take:** most visitors with a few days in San Pedro de Atacama do both, this shorter, lower altitude float early in the trip while still acclimatizing, then the longer altiplanic circuit once they have had a rest day. ## What Should You Actually Bring? Swimwear under your clothes, since there are no proper changing facilities at the lagoon itself, plus a towel and biodegradable sunscreen specifically, since standard sunscreen can affect water quality in an enclosed salt lagoon like this one. Bring fresh water too, both to drink and to rinse with afterward, since the salt dries on skin and clothing fast and gets noticeably uncomfortable if left too long. **I would pack cash as well.** The lagoon entrance fee is typically paid separately from the tour price, often in cash, since card payment through a link can carry a processing surcharge on a trip like this. ## Is the Entrance Fee Included in the Tour Price? Usually not. The tour price covers hotel pickup, a bilingual guide, and a sunset cocktail at the end of the visit, but the lagoon entrance fee itself is a separate charge, paid in advance and often in cash, confirmed directly with your operator at booking. **My honest advice:** ask about the exact entrance fee arrangement when you book rather than assuming it is bundled, since this is exactly the kind of detail that makes one listing look cheaper than another while actually costing the same once you add the fee back in. ![Simple infographic comparing a floating figure icon in Laguna Cejar against a scenic van-tour icon for the full-day altiplanic lagoons circuit, flat design, generic labels only, laguna cejar tour versus full-day lagoon comparison](/images/blog/san-pedro-de-atacama-laguna-cejar-floating-guide-2.webp) ## How Far Is Laguna Cejar From San Pedro de Atacama? Close, roughly 30 to 40 minutes by van, reaching altitudes up to around 2,500 meters, considerably gentler than the altiplano excursions further out of town. That proximity is a big part of why this makes such an easy half-day addition to a short trip. **I think this is genuinely one of the lowest effort bookings in the desert.** You do not need a rest day beforehand the way you would for the higher altiplanic lagoons, and the whole trip, including the drive both ways, runs around 5.5 hours door to door. ## What Else Happens on the Tour Besides Floating? The route includes a short stop at Ojos del Salar, a pair of deep, cold freshwater springs sitting oddly in the middle of the salt flat, where almost nobody actually swims since the water is noticeably colder than Cejar. The day finishes at Laguna Tebinquinche, a shallow, mirror-like lagoon known for sunset reflections of the surrounding volcanoes, where the group is served a sunset cocktail to close out the visit. **My honest take:** I would not rush past Tebinquinche just because the floating part is already done. The mirror effect at sunset is its own small highlight, and the cocktail stop is a nice, low-key way to end a swim-focused afternoon. ## Is Laguna Cejar Suitable for Children? Not for very young kids specifically. The operator generally does not recommend this tour for children under 6, and I would take that guidance at face value rather than assume it is overly cautious, since comfort in open water matters here even with the buoyancy assist. **I would also mention this to non-swimmers directly**, regardless of age. The salt water makes floating easy, but genuine unease around deep water does not disappear just because staying afloat takes less effort, so flag it to your guide before getting in. ## Should You Book Laguna Cejar or Baltinache? Book Laguna Cejar if a guaranteed float is the point, since swimming at [Baltinache](/salar-de-atacama-lagoons-guide/baltinache-hidden-lagoons-alternative/) is currently paused for maintenance and natural regeneration. Baltinache still has a real appeal as a quieter, more remote lagoon visit, just not as a swimming trip right now. **My honest read:** if floating is the entire reason you are considering either tour, this one is the clear pick today. Save Baltinache for later in your trip, or for a return visit once its lagoons reopen for swimming. ## Does Puritama Hot Springs Make a Good Pairing? Yes, and for a genuinely different reason than you might expect. [Puritama Hot Springs](/salar-de-atacama-lagoons-guide/puritama-hot-springs-guide/) is a warm thermal canyon rather than a cold salt lagoon, so pairing the two across different days gives you both ends of the water experience this desert offers, one cooling and briny, one warm and mineral. **I would not do both on the same day**, mainly because the logistics and the driving add up. Spread them across your trip instead, and treat each as its own relaxing half-day rather than squeezing both into one. ## What Time of Day Should You Book? Afternoon departures are the norm, timed so the group reaches the lagoon with enough daylight left to float, dry off, and still catch the sunset stop at Tebinquinche before heading back. I would not try to book an earlier morning slot if one happens to be offered, since the whole itinerary, including the sunset cocktail, is built around that later timing. **My honest take:** the afternoon slot also means you are not giving up a morning you could spend on another excursion elsewhere in the desert, which makes this an easy tour to slot into a day that already has something else planned earlier. ## Is the Water Actually Clean? Yes, and the high salt concentration itself works against bacteria in a way fresh water does not, which is part of why these lagoons stay in good condition despite heavy daily visitor traffic. That said, the biodegradable sunscreen requirement some operators enforce exists specifically to protect that balance, so it is not just a suggestion. **I would follow it regardless of what your own operator asks for.** Standard sunscreen genuinely can affect water quality in an enclosed lagoon like this one, and a small change on your part costs nothing compared to what it protects. ## My Honest Recommendation Book the Laguna Cejar tour if floating in genuinely strange, dense salt water is the experience you are after, and do it early in your trip since the altitude here barely registers compared to the desert's higher excursions. Bring biodegradable sunscreen, a towel, and cash for the entrance fee, and do not skip Ojos del Salar and the Tebinquinche sunset stop just because the floating part is already done. If you want the scenic, higher altitude version of the Salar de Atacama instead, my [full lagoons and Piedras Rojas guide](/salar-de-atacama-lagoons-guide/) covers that longer circuit in detail. Chile's official tourism board, [SERNATUR](https://www.sernatur.cl), publishes general guidance on visiting the Salar de Atacama responsibly, worth a skim before your trip. ## Frequently Asked Questions **Do you really float without effort in Laguna Cejar?** Yes, the water's high salt concentration makes buoyancy effortless, similar to the Dead Sea. **Is the Laguna Cejar entrance fee included in the tour price?** Usually not, and it is typically paid in cash before the itinerary starts, so confirm the current arrangement with your operator. **How is this different from the full-day Salar de Atacama tour?** This is a half-day recreational float focused on one lagoon, while the full-day combo is a scenic circuit covering Piedras Rojas and two higher altiplanic lagoons with no swimming involved. **Is Laguna Cejar suitable for children?** The operator does not recommend this specific tour for children under 6. **Should I book Laguna Cejar or Baltinache for floating?** Book Laguna Cejar if floating is your priority, since swimming at Baltinache is currently paused for maintenance.
