- In March 1988, Prince Charles was involved in an avalanche accident that killed his close friend, Major Hugh Lindsay, at Klosters, a Swiss ski resort.
- The accident has come back into focus as a storyline in season four, episode nine of Netflix's hit series "The Crown."
- Diana never went back to Klosters after the accident, but Charles returned throughout the '90s and 2000s with their children, Prince William and Prince Harry.
- Take a look inside the famously discreet resort where Prince Charles has two cable cars dedicated to him, and Will and Kate Middleton were first photographed sharing a kiss.
Warning: Spoilers ahead for the fourth season of Netflix's "The Crown."
