href="http://www.eso.org/public/teles-instr/lasilla/">La Silla Observatory</a> is located 600 km north of Santiago and about 160 km north of La Serena at an altitude of 2400 metres, bordering the southern end of the Atacama Desert in Chile. At La Silla ESO operates several of the most productive 4-metre-class telescopes in the world. La Silla <span style="line-height: 18.5714092254639px;">has been an ESO stronghold since the 1960s. </span><span style="line-height: 18.5714092254639px;">It is equipped with several medium-sized optical telescopes and is home to the world’s foremost exoplanet hunter: HARPS (High Accuracy Radial velocity Planet Searcher), a spectrograph with unrivalled precision.</span></p> <div style="margin-top: 30px; margin-bottom: 30px; text-align: center;"> <a href="http://www.eso.org/public/images/safety-la-silla/"><img src="/public/archives/images/screen/safety-la-silla.jpg" alt="La Silla site map" style="max-width: 100%;"></a> <div><small><em>La Silla site map.

The nearest airport is <a href="http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Aeropuerto+La+Florida,+La+Serena,+Chili&sll=-29.91596,-71.199474&sspn=0.038462,0.066175&ie=UTF8&hq=&hnear=La+Florida+Airport,+Chile&ll=-29.916108,-71.199474&spn=0.038462,0.066175&t=h&z=14">La Florida</a> at <a href="http://www.eso.org/public/about-eso/travel/laserena.html">La Serena</a>. There is no public transport to La Silla Observatory, so you will need to rent a car (see below).</p> <h3>Arriving by car</h3> <p>Some of the car rental companies based at the airport are <a href="http://www.econorent.cl/" target="_blank">Econorent</a>, <a href="http://www.budget.cl/" target="_blank">Budget</a> or <a href="https://www.hertz.cl/" target="_blank">Hertz</a>, and average daily cost of a rental car is CLP 50 000 (EUR 70).</p> <p>It takes around two hours to drive from the airport to La Silla. Drive west down Av. Colo Colo to reach the Pan-American Highway. Turn right (north) and continue to route C-541. Turn right to take this route and continue to the La Silla main gate.</p> <p>Driving from the north, the turn is reached after Vallenar; from the south, it is after La Higuera.</p> <p>Please check the <a href="http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=La+Silla+Observatory,+Chile&sll=-29.439598,-70.784912&sspn=4.945692,8.470459&ie=UTF8&hq=La+Silla+Observatory&hnear=La+Silla+Observatory,+Chile&ll=-29.204918,-70.85083&spn=2.478875,4.235229&t=h&z=8">external map</a>. <strong>Please note that ESO does not provide fuel to visitors. You must have sufficient fuel in your car to be able to drive to your next destination.</strong></p> <h2>Accommodation and Food at La Silla</h2> <p>Overnight accommodation and meals at La Silla are available for ESO staff only.</p> <p>For accommodation, you can return to <a href="http://www.eso.org/public/about-eso/travel/laserena.html">La Serena</a>.</p> <p><span style="line-height: 18.5714092254639px;">Accommodation and meals are provided only in the exceptional case of specially authorised media visits. For further information on media visits please check </span><a href="http://www.eso.org/public/outreach/pressmedia/mediavisits/">here.</a></p> <h2>Health & Safety</h2> <h3>Weather and Clothing</h3> <p>La Silla is located on a remote site bordering the southern end of the Atacama Desert. You may be exposed to strong winds and high solar radiation. Please wear appropriate clothing such as trousers, walking shoes (no sandals), sunglasses, etc. We recommend a jacket or sweater for the enclosures, which are kept at 5 – 11°C. The average humidity on La Silla is between 2 and 10%.</p> <p>For climate information in La Serena you can check <a href="http://en.wikipedia.org/wiki/La_Serena,_Chile#Climate">here</a>. You can also find a short-term weather forecast <a href="http://www.accuweather.com/en/cl/la-serena/53361/weather-forecast/53361">here</a>.</p> <h3>High Altitude Health Issues</h3> <p>If while staying in La Silla you experience any of the following, please report it to a local staff member immediately: acute headache, dizziness, breathing problems, ringing or blocking of ears, heart pains, acute muscular pains, seeing "stars".</p> <h3>Recommendations</h3> <ul> <li>Drink extra water or juice. Do not drink water from the faucets.</li> <li>Alcohol is forbidden at all ESO high altitude sites, not only because of its inebriating properties, but also because it can increase the risk of dehydration.</li> <li>Eat light, high-carbohydrate meals.</li> <li>Avoid sedatives and similar medication.</li> <li>Never use medicinal treatment instead of descending, without consulting an ESO physician or paramedic at the site.</li> <li>Use skin protection: wear a hat and clothing that covers arms and legs; apply a broad-spectrum sunscreen of sun protection factor 15+ liberally on areas of the body not protected by clothing, and reapply it frequently.</li> <li>Use eye protection: wear UV-protection sunglasses of a wrap-around design, and a wide-brimmed sun hat.</li> </ul> <h3 style="font-family: 'Neue Helvetica W02', 'Neue Helvetica W10', 'Helvetica Neue', Helvetica, Arial, sans-serif; color: #333333;">Virtual tour</h3> <p style="line-height: 18.5714092254639px;">Experience the ESO La Silla Observatory with <a href="http://www.eso.org/public/products/virtualtours/lasilla/">ESO's Virtual Tours</a>.</p> </div> <div class="col-md-4 col-sm-12 col-xs-12"> <div class="details-sidebar"> <p><iframe src="https://maps.google.com/maps?cd=1&ei=0Y-sS6nILIWe_Abrs6CEBQ&sig2=Sq5tZkW4lbgTri_fFY5B3w&sll=-29.253577,-70.731333&sspn=5.816537,11.634521&hl=en&ie=UTF8&view=map&cid=15464744748766028655&q=La+Silla&ved=0CBYQpQY&hq=La+Silla&hnear=&ll=-29.260925,-70.731633&spn=0.006295,0.006295&t=h&iwloc=A&output=embed" marginheight="0" marginwidth="0" style="width: 100%; height: 400px;" frameborder="0"></iframe><br> <small><a href="https://maps.google.com/maps?cd=1&ei=0Y-sS6nILIWe_Abrs6CEBQ&sig2=Sq5tZkW4lbgTri_fFY5B3w&sll=-29.253577,-70.731333&sspn=5.816537,11.634521&hl=en&ie=UTF8&view=map&cid=15464744748766028655&q=La+Silla&ved=0CBYQpQY&hq=La+Silla&hnear=&ll=-29.260925,-70.731633&spn=0.006295,0.006295&t=h&iwloc=A&source=embed">View Larger Map</a></small></p> <p class="beware"><strong>Address:</strong><br> ESO La Silla Observatory<br>Región de Coquimbo<br> Chile</p> </div> </div> </div> </div> </div> </div> </div> </div>  <div class="row footernote"> <div class="col-xs-12 col-md-3"> <a href="mailto:information@eso.org">Send us your comments!</a> </div> <div class="col-xs-12 col-md-3"> <a href="/public/outreach/newsletters/esonews/">Subscribe to receive news from ESO in your language</a> </div> <div class="col-xs-12 col-md-3"> <a href="https://www.cdn77.com">Accelerated by CDN77</a> </div> <div class="col-xs-12 col-md-3"> <a href="/public/about-eso/privacy/">Terms & Conditions</a> </div> </div> <link href="/public/archives/djp/css/extras.d3e54451ebbb.css" rel="stylesheet" type="text/css" /> <script type="text/javascript">var MEDIA_URL = "/public/archives/"</script> <script type="text/javascript" src="/public/archives/djp/js/main.86aaf133ddd1.js" charset="utf-8"></script> </div>  <div id="social-share" class="hidden-print"> <div class="link facebook" data-toggle="tooltip" data-placement="right" title="Share on Facebook"> <a href="https://www.facebook.com/sharer/sharer.php?u=https://www.eso.org/public/about-eso/travel/lasilla/" target="_blank" rel="noopener noreferrer"><i class="fa-brands fa-facebook-f" aria-hidden="true"></i></a> </div> <div class="link twitter" data-toggle="tooltip" data-placement="right" title="Share on X/Twitter"> <a href="https://twitter.com/intent/tweet?url=https://www.eso.org/public/about-eso/travel/lasilla/&text=Travel to ESO La Silla&via=ESO" target="_blank" rel="noopener noreferrer"><i class="fa-brands fa-x-twitter"></i></i></a> </div> <div class="link pinterest" data-toggle="tooltip" data-placement="right" title="Share on Pinterest"> <a href="https://pinterest.com/pin/create/button/?url=https://www.eso.org/public/about-eso/travel/lasilla/&media=&description=Travel to ESO La Silla" target="_blank" rel="noopener noreferrer"><i class="fa-brands fa-pinterest-p" aria-hidden="true"></i></a> </div> <div class="link print" data-toggle="tooltip" data-placement="right" title="Print"> <a href="javascript:window.print()" target="_blank" rel="noopener noreferrer"><i class="fa fa-print" aria-hidden="true"></i></a> </div> <div class="link email" data-toggle="tooltip" data-placement="right" title="Share by email"> <a href="mailto:%20?subject=ESO — Travel to ESO La Silla&body=https://www.eso.org/public/about-eso/travel/lasilla/" target="_blank" rel="noopener noreferrer"><i class="fa-regular fa-envelope" aria-hidden="true"></i></a> </div> </div> <script> $('[data-toggle="tooltip"]').tooltip(); </script> <input type='hidden' name='csrfmiddlewaretoken' value='nG439TB0UDfn6qAuD2ty37Xnz8p2x4zcFGMtZvxc6yQpRTro3W9vwEje5inJdKQI' /> </body> </html>
