A Rule of Thumb for Viewing Hawaiian Monk Seals

October 06, 2021

Enjoying Hawaiian monk seals from a distance is easy with this simple rule of thumb!

Rule of Thumb for Hawaiian Monk Seals

Use the "rule of thumb" to determine a safe distance (if no signs or barriers are present).

  1. Make a "thumbs up" gesture and extend your arm straight in front of you.
  2. Turn your thumb parallel to the ground in your line of sight of the seal.
  3. If your thumb covers the entire seal, you are likely far enough away (about 50 feet or 15 meters)
