Canyoning （蹦谷运动）
The sports of canyoning explore the high-energy environment where water meets rock on the coast，or in river canyons．Protected by wetsuits and helmets （头盔），people jump from cliffs （悬崖） and waterfalls and explore caves and river canyons that would not normally be arrived at．
It was pioneered in the U．K．by TYF Adventure （01437 721611，www．tyf．com） and several thousand people leap from the cliffs near St David's each year．A half day canyoning trip costs￡50 （￡30for children under 16）．
Scuba diving
Diving is not popular with British people．The challenges of wild waters are greater because the water is colder and not clear enough，but the coasts of Cornwall，Wales and Scotland have some of the best wreck diving in the world．
The British Sub Aqua Club （0870 112 9133www．bsac．com） and the Professional Association of Diving Instructors （01580 819688www．padi．com） run courses teaching the important skills right up and to instructor level．
Surfing
The best surfing places in the UK are on the southwest coast where it is warmer and the surf is relatively steady，particularly in Cornwall．The best time of year to surf in the UK is late summer and autumn when water temperatures are at their mildest．
The British Surfing Association （01479 861256www．britsurf．co．uk） has a list of famous surf schools around the country．
Rock climbing
The most popular natural rocks in Britain include the Peak District，the Lake District，coastal regions，while vast areas of Scotland are a climber's paradise （天堂）．Climbing courses and climbing walls can be located on the website of the British Mountaineering Council （0870 010 4878，www．thebmc．co．uk） which offers a series of short films that take the new climber through a step-by-step guide to visiting a climbing wall for the first time．
