The old Gas Works overlooks Lake Union, on the edge of the freaky Fremont neighbourhood which is home to the huge Fremont Troll sculpture and a statue of Lenin, among other curiosities. The former coal plant has been turned into a beautiful green space that retains most of its distinctive industrial features, and has been made safe via various eco-friendly additions to the soil. Now the park is open for concerts, games or just a good stroll around the old Gas Works perimeter to enjoy some seriously quirky architecture. (Image credit: WikiPedant)

Take a trip to the site of a volcanic eruption which happened 80,000 years ago to see some of Oregon’s most beautiful natural features. The Lava River Cave is more than 5,000 feet long and curves its way beneath Deschutes National Forest. A guided tour takes visitors a mile deep into the cave to explore its innermost secrets – and the beach-like conditions at the bottom where the steady trickles of sand collect at its lowest point.

Home of California’s largest man-made lake, the National Forest is an ideal destination for getting away from the weirdness – for a little while. And although the California climes may not seem like the place for a spot of cross-country skiing, the peaks of Mount Shasta offer just that. In the warmer weather, Lake Shasta provides an ideal getaway, with boating and fishing available alongside some lakeside lazing.

Back to the city – and a musical interlude, with the Wave Organ out in the Marina District. As the tide comes in, listen out for a haunting musical accompaniment created by the rush of water against a set of PVC pipes which engineering maverick Peter Richards had installed in the 1980s. Time and tide have lessened the volume and pitch, but the sound is nonetheless still distinctive – and a hidden gem of the San Fran scene.

Dr Frederick Finch Strong donated most of the components of his working Tesla coil to the city in the 1930s, and to this day it remains one of the most popular displays at the remarkable Griffith Observatory. Nikola Tesla originally conceived the coil as a way to test his theories about electricity and how it travels – today, tinkerers and other science enthusiasts gather to watch its hourly demonstrations.

This museum celebrates all things fast foody – not surprising given as it stands where the very first branch of McDonald’s was built. There’s a huge collection of merchandise, including decades’ worth of Happy Meal toys displayed in glass cases. Another highlight of the guided tour is the original 1940s menus being displayed – alongside its more recognisable options, the original branch used to offer barbecued beef and hot tamales.

As you pass through Nevada you’ll find many roads leading to Vegas, but persist and you’ll be rewarded with a walk around an area once used as an atomic testing site both above and below ground. Real atomic explosions have happened in this small ‘village’ out in the desert, and a guided tour can now take you around these sites of devastation. Cameras are not permitted, and the lifting of rocks from the site is strictly prohibited – so no ‘souvenirs’. (Image credit: US Department of Energy)

This unusual roadside attraction came about when two artists joined forces to sow their imaginative seed into the grounds of Goldfield – in the form of more than 40 dishevelled cars in various states of wreckage. With some half-buried in the ground and others stacked like toys, this surreal symbol was dubbed a ‘forest’ by its creators, and attributed to a force more powerful than organised religion.
