Coll & The Cosmos Stargazing Weekend – September 2017

Saturday 16th September 2017 from 12:00pm to Monday 18th September 2017 12:00pm

Isle of Coll - Coll Bunkhouse

Arinagour, Isle of Coll, PA78 6SY


For the stargazing adventure of (perhaps) a lifetime make your way to the remote Isle of Coll for this weekend exploring the incredible dark skies above the island.

This event is for anyone and everyone! No prior knowledge of astronomy is needed -- you'll experience dark skies like you have never done before. Absorb the views through large telescopes and let your mind take yourself away to distant galaxies!

A state of the art mobile planetarium will be on site as a great alternative if the weather doesn't play along.

After your long stargazing night and even longer lie-in go off to explore the wonderful scenery around the island.

Spaces are limited -- best book up soon before we do! Website link below...

- Event is a hosted at a dark sky location such as a remote campsite over several nights usually around a new moon when the skies are dark.
