The Halloween Express hits the rails in Boulder City at the Nevada State Railroad Museum. Passengers can ride the full-size train on the historic Nevada Southern Railroad with scary and not-so-scary ghosts, ghouls and goblins beginning at 10 a.m. The seven-mile round trip is less than 30 minutes from Las Vegas, on the way to Hoover Dam. Additional trips depart at 11:30 a.m., 1 and 2:30 p.m. both days. The Halloween celebration also includes face painting and balloon twisting. Rides are $10 for adults ages 12 and older, $5 for children 4 through 11 and free for children under 4. Children 11 years old and under can ride for free if they are in costume.
