The cruise departs Oban railway pier hourly until October (weather permitting). Maximum of 12 persons. Pay on boarding.
The service heads past Kerrara. The views are amazing, and the further the boat gets out, the prettier the seascape, hills, and rocky islands become. The mountian views are spectacular. The day I did the cruise, there was a rainbow over a distant island. On the other side, there are views of the bay of Oban and Dunollie castle ruins.
After about 20 minutes, the boat comes near a rocky island where seals bask and swim. The boat doesn't get close enough to frighten them, but close enough to see them clearly.
The seals were mainly basking in the sunshine, and swimming and diving. They didn't seem to be bothered by our presence. Seals in the water kept popping their heads up, and it was funny watching people trying to take photographs of them - they disappeared beofre the photo was taken, only to pop up somewhere else.
I highly recommend this cruise - the seals are so incredibly cute and the scenery is lovely. We saw loads of seals. However, the cruise is worth it even if you don't, as the scenery is so nice. The boat has outdoor seating only, so wrap up warm, and bring plenty of camera film.
