Watch footing, weather, and wildlife, and tell someone where you are going.

Wear stable shoes and avoid slick rocks after rain. Keep a respectful distance from deep drop-offs and fast current.
Pack water, sun protection, and a basic first-aid kit. Phone batteries drain faster outdoors — bring a small power bank.
Be aware of snakes, insects, and changing weather. Leave no trash, including line scraps that harm birds and pets.
