Here are some essentials to be aware of:

  • The tour area is remote. Water Bureau staff carry emergency radios and are trained in first aid; however, cell phones do not work and emergency care can be more than an hour away.
  • Restrooms can be up to 2-3 hours apart. Please contact us if limited restroom availability presents a challenge for you.
  • Smoking/vaping/e-cigarettes are not allowed.
