|Adrenalin X-treme Adventures
||San Vigilio, N. Italy
||They call this one "Europe's biggest zip line" because it is not one, but 10 zip wires zig-zagging between platforms down the sides of a steep valley (a ski piste in winter time) in the Italian Dolomites. The total length is 3.2 kilometres, over a 420 metre drop. Max speed 80 kmph.
|Cable Vuelo Chicamocha
||A slightly odd zip line system with riders slung from a pair of parallel cables. Their descent is slowed at the end by crashing into a large pad (Pads are not unusual, but usually there's a pre-pad breaking system. Somebody died crashing into it head first w/o a helmet in 2009) And judging by one video riders are loaded at the bottom station before being hauled in groups up to the top for release. There are three different zip lines: the longest is 450m, the shortest is designed for kids. The park is also home to one of the world's longest cable car systems covering 6.3 kilometres.
|Dragon's Breath Zip line
||The longest zip line in the Caribbean runs over land and water for 790 metres (899 yds). The zip line starts 500 feet above Labadee beach and can reach speeds of 50 mph. Some cruise lines like Disney, have their own private island resorts. Royal Caribbean has a private resort on the north coast of Haiti, which is where they operate this zip line.
||Puys de Sancy, France
||Opened July 2013, this is another from the Fantasticable company (see notes below). Super-Besse is a purpose built winter sports resort (1350m) in the middle of France in the Parc naturel régional des volcans d'Auvergne. The zip is 1600m long, drops 250m, and reaches speeds up to 120kph.
|Flyin Hawaiian Zipline
||Eight ziplines from 250ft (76m) to Hawaii's longest zip at just over a kilometre long (3,600ft) combine to cover 2½ miles of the West Maui canopy stretching from Waikapu to Ma‘alaea.
|Hollybank Treetops Adventure
||A 214m zip line across a deep valley, above the Hollybank Forest and Pipers River. It made Grumpy Traveller scream like a girl, so that has to be good, eh?
|Il Volo dell’angelo
||Claims to be the world's fastest at 120kph, but is actually out-paced by at least three others in Europe. All the same it is pretty dramatic and unusual. There are two lines stretched between the mountain top villages of Pietrapertosa & Castelmezzanos. The first starts at 1020m in Pietrapertosa and arrives in Castelmezzano at 859m after covering 1415 meters with the top speed of 110 kph. Then you climb up the hill to 1019m and travel back 1452m to Pietrapertosa at 888m, reaching 120 km/h on the way. Big speeds, big distances and one of the unusual aspects is that it also takes a double harness so two can 'fly' together.
||Chiang Mai, Thailand
||Actually not one zip line but a treetop jungle trail over several miles with 20 zip lines (the longest 300m), linking 33 Platforms and 3 sky bridges.
||A multi zip line experience through the canopy of Daintree Rainforest at Cape Tribulation. There are four zip lines. The longest is 78 metres.
||Seven pairs of zip lines (parallel lines so you can zip side-by-side) covering two miles, including two lines over 2,000 feet long (610m).
|Laggen Outdoor Activity Centre Zipline
||I feel sorry for these guys. When it opened in June 2012 it was billed as the UK's longest... then Zip World opened in North Wales. All the same it is half a mile long (0.82km), and its vertical drop is 110m, giving riders speeds up to 50mph.
||Marble Mountain, Newfoundland
||Nine zip lines ranging in length from 150m to 600m (approx 500 - 2,000ft), zig-zagging across the dramatic Steady Brook Falls with views over the Humber Valley. Their claim to fame is that at 87m (285ft) above the ground they have the "highest" zip line in Canada.
||The Pena Aventura park has a 1538 metre Fantasticable zip line, dropping 150 metres, with speeds up to 130 kph.
|Piiholo Ranch Zipline
||Five ziplines with one at 1,420ft (432m).
||The first Zipline Company in the United States (you can tell from their url!), established in 2002, which may help to explain why there are so many ziplines on Maui. They now have four zipline tour locations, each with 5-8 lines: two on Maui, one on Big Island and one on Kauai. No lengths given.
||Monteverde, Costa Rica
||Ten zip lines - the longest is 750 metres - covering 1.7 miles of jungle, linking treetop canopy platforms and walkways.
|SkyWire at the Eden Project
||The Eden Project (probably now Cornwall's best-known tourism attraction - controlled climate biomes set in a 35 acre former quarry) has installed a 660-metre zip line, which they claim is England's (note the distinction) longest. Tests have seen speeds up to 60mph.
||Fumay, N. France
||Woodland aventure park in the Ardennes with a Fantasticable zipline that sails across the river Meuse at high speed (130kph/81mph) for over 1 kilometre. Quite a ride!
|Toroverde La Bestia
||Orocovis, Puerto Rico
||The Toroverde eco park has eight ziplines, and The Beast - 4,745 feet (1.446km) long, travelling at speeds up to 60mph.
||Sun City, South Africa
||For now the longest zip line in the world at 2 kilometres long (6,561 feet)! Speeds reach 90 kph over the 280 metre vertical drop.
||Claims to be world's most extreme zipline. Its vertical drop of 600 meters over a total distance of 1.8km makes this the world's steepest, tallest and one of the longest ziplines. It is also one of the fastest with top speeds of up to 140 kmph. It is located on Sarangkot, about 10 km from Pokhara.
||Icy Point, Alaska
||Probably the longest in North America, but their claim is "The world's largest", by which they mean the combination of length and vertical drop. The Icy Point zip line is 1.6 kilometres (5,330 feet) long, descending almost 400m (1,300ft) in around 90 secs (60 mph maximum speed)
||Bethesda, North Wales
||At 1.46 kilometres (4,800 ft) long, this new zip line in what used to be the world's largest slate quarry, is claimed to be the longest in Europe, and reaches speeds up to 100mph (160kph)! There's no doubt about it, this is easily one of the most extreme zip lines, and it's in the UK.
