Beware of swimming in Lot's Ponds. Many people have drowned here. The water may look calm and inviting, but suddenly a wave will come from nowhere and take you away.
A few places are dangerous to walk due to crumbling rock and erosion, or treacherous seas. There will be danger sign posts warning you - obey these - they are there for a reason - even if you THINK you will be safe. Listen to the people who live there and know about these dangers.
