Tours and Visiting Information

Historic Mount Wilson Observatory is an astronomical research facility located in the San Gabriel Mountains of Southern California. Located on the summit of Mount Wilson above Pasadena at an altitude of 5715 feet (1742 meters), the observatory is visible from much of the Los Angeles area. Visitors can view the historic Hooker 100-inch telescope from the Visitors' Gallery inside the dome. There is also a small Astronomical Museum on the observatory grounds. Picnic tables are available at the Pavilion near the main parking lot where a commanding view of the Los Angeles basin is seen on clear days. Note that due to continuing fire danger smoking is not permitted on the observatory grounds except inside closed vehicles.

Date and hours for visiting
The observatory is open to visitors every day from 10 AM to 4 PM from April 1 through November 30, weather permitting. The gate into Skyline Park and the observatory's buildings are closed to the public the rest of the year (December 1 through March 31), although special group tours can still be requested (see below). The observatory may be closed at other times after heavy snowfalls, when dangerous icy conditions exist or during times of high fire danger. Please check here again just before your visit for the observatory's current visiting status.
Food is available for purchase on the mountain only on Saturdays and Sundays from 10:00 am until 4:00 pm at the Observatory's Cosmic Cafe located in the Pavilion overlooking the large parking lot at the entrance to the Observatory grounds. The Cosmic Cafe serves a variety of fresh-made sandwiches, hot and cold drinks and other treats as well as souvenirs. In addition to those whose intent is to visit Mount Wilson Observatory, hikers, motorcyclists, and bicyclists will find the Cosmic Cafe a welcome stop before returning from their venture into the San Gabriels.

Special Access Notice
Access to Mount Wilson via the Angeles Crest Highway has been interrupted by road collapse as a result of the rains following the Station Fire in 2009. The road is not expected to reopen until sometime during the late summer of 2010. Access is now provided by an alternate route through a combination of Los Angeles County and Cal Trans roads starting at the Sunland Blvd exit of the I-210 Freeway. Here, you can download a map and turn-by-turn directions for this alternate route. Consult the Los Angeles County road information for their current status.
Note that large portions of the Angeles National Forest within the Station Fire burn area remain closed in spite of the opening of the roads to allow passage through the Forest. Drivers are reminded to follow all posted Forest Closure signage while traveling to and from the Observatory.

Free Weekend Walking Tours Walking tours of the observatory are led by docents provided by the Mount Wilson Observatory Association at 1 PM on Saturdays and Sundays, from the first weekend of April through the last weekend of November, weather permitting.

Weather Weather conditions in the mountains can vary greatly and change suddenly. Be prepared for any weather conditions including snow and local dense fog. The weather is often much different on the mountain than in the city below. A live image from the observatory can be seen on the Towercam mounted at the top of the 150-foot solar tower telescope. The image is updated every four minutes and weather conditions are often posted on the Towercam page by the solar astronomers on duty. Remember that conditions on the mountain may change from what you see on the Towercam.

Other activities on the mountain Hiking and cycling are popular activities on and around Mount Wilson. CORBA offers information about off-road cycling trails. The U.S. Forest Service can provide maps and information on hiking trails in the area. The mountain and surrounding areas are rugged and wild. Extreme care should be taken when venturing off the highway.
