- The trail is short but steep, with stairs and little shade. Bring water, a hat and sunscreen, and go early on hot days.
- Wear shoes with grip; the path is uneven and can be slippery after rain.
- If you have heart or lung conditions, take it slowly, rest often and turn around if you feel unwell.
