Widely known as the site of a supposed 1940s UFO crash, the city of Roswell has cleverly developed a number of alien-related sites, tours and museums that attract visitors interested in the paranormal. One of the city's biggest draws is the International UFO Museum and Research Center, which collects information on possible alien sightings from all over the world. This organization has helped establish the Roswell UFO Festival, which occurs over the Independence Day weekend in July. For those wanting more alien treks, the well-known Hangar 84 occasionally allows tours through limited parts of its facility, which once housed the wreckage from the questioned crash. After seeing these facilities, there are plenty of natural areas to visit. New Mexico's first state park was established near Roswell—the Bottomless Lakes—where visitors can go swimming, hiking, camping, fishing, boating and picnicking. After a day of activities, guests can relax by seeing a performance by the Roswell Symphony Orchestra or the Roswell Community Little Theatre.
