A mountain coaster or alpine coaster is a gravity driven amusement ride with bobsled-like cars on tracks installed on a mountain. It is similar to alpine slides where a low-wheeled sled is used to navigate the track but instead of running over a smooth concave tracks like the alpine slide, alpine coasters run on rails with up-stop wheels like roller coasters. Thus, alpine coasters are safer and faster than alpine slides as it prevents overturning when going too fast on a curve. Tracks are tubular rails like a steel roller coasters while some have monorail-type tracks. But unlike a roller coaster, the rider has the capability to control their speed with its rider-controlled brake system. Alpine coasters can also operate year-round even through light rain and snow.
Safety features, speed, tracks and layout vary by manufacturer. Leading makers of mountain coasters (with trade marks in parenthesis) include Wiegand (Alpine Coaster), Brandauer (Summer Toboggan), Alpine Products (Alpine Mountain Coaster), and Erbschloe Fun Construct (Rolba Bob).
The longest alpine coaster in the world is Tobotronc at Naturlandia in the tiny Principality of Andorra in the Pyrenees Mountains between France and Spain. It is 5.3 km long. The highest alpine coaster in the world is the Alpine Coaster of Glacier 3000 in Gstaad, Switzerland with the starting elevation of 9,747 feet (2,971 m) and a length of 3,300 feet (1,000 m).
The predecessor to the mountain coaster is the alpine slide, which came out in the 1970s. A German company in Rasdorf, Wiegand, installed the first stainless steel tracks for the alpine slide in 1975 rather than the customary fiberglass or concrete tracks. The company later developed the first mountain coasters in 1997. Josef Wiegand, the owner, envisioned the idea of creating a roller coaster-type ride for ski resorts that would take advantage of the topography of the land, rather than building the structure to create the elevation changes that traditional roller coasters require. The company installed its first coaster under the "Alpine Coaster" trademark in 1997.
In 2007, Alpine Products, one of the largest manufacturer of alpine slides, entered the market with its "Alpine Mountain Coaster". The company is the first maker to add an anti-collision system that detects cars ahead, warns, and stops the cars when needed, among other safety features.
Most mountain coasters are installed by ski resorts as an added year-round attraction or installed seasonally to augment income during summer months. The latter have easily removable tracks that are placed over the ski runs after the ski season. All mountain coaster tracks are devised for easy installation with minimal impact to the topsoil and environment as most tracks are build close to the ground taking advantage of the natural elevation of the terrain. No concrete work is needed except at the station. Some bridgework up to 5 metres (16 ft) tall are installed by manufacturers to adjust for roads, trails, ski slopes or water way crossings. Aluminum or stainless steel are used for the tracks for low maintenance and durability.
Some tracks are closed loop and include a lift system during the course of the ride. Some coasters on ski resorts eliminate the long tedious climb up to the top by utilizing the resort's ski lift to take the riders to the top of the course, so the riders can just enjoy a longer one-way downhill run back to the station. Mountain coaster erected as rides on amusement parks are usually closed-loop coasters.

Thrill elements on mountain coasters could include varying degrees of curves, dips and hairpin turns. Large spiral circles (helixes) are not only used as a thrill element but also for reducing elevation.
Each sled accommodates one or two passengers and is controlled by a hand brakes located on both sides of the car or one single brake lever in the middle of the car on Brandauer coasters. Riders are advised to place their hands on the brakes at all times for safety reasons. Pulling the hand brake handle causes the cart to stop; pushing or letting go of the handle causes the brakes to release, allowing the cart to accelerate.
Alpine coasters are unique among amusement park rides in that the rider has complete control over his or her speed and ride experience. Riders can opt for slower leisurely run or with minimal or no braking for faster thrilling rides.
Most cars are equipped with centrifugal brake system which controls its maximum speed by limiting the rpm of the run rollers. Riders are responsible to observe a safe distance as a common courtesy to the riders in front. Each cars are equipped with shock-absorbing front and rear bumpers in case of collision, which occurs when riders are driving too fast and leaving not enough space for braking distance. Newer generation coasters are equipped with an anti-collision system, which automatically apply the brakes if the rider gets too close to the car ahead.
To secure the riders on their seats, each car is equipped with a three-point safety belt for the rider and a lap belt for the passenger. Tracks also have safety nets especially on steep curves as a precaution.
