Manx National Heritage is urging walkers, climbers and drone operators not to disturb nesting birds at The Chasms and Sugarloaf Rock.
To protect seabirds during the spring and summer, climbing and drone use is banned until Saturday, August 1.
The charity is reminding people it's in a offence to deliberately or recklessly disturb nesting wild birds.
It's also warning seabirds may be carrying bird flu, and the area could be closed off because of this too.
