Not far from Duach beach is East End Bay which is bigger and more accessible, as the road runs alongside it. To get here takes about 40 minutes from the ferry pier.
East End isn’t as nice as Duach but it’s still very attractive. The beach is more open, but is nicely curved and, again, the water is clear. If you are feeling adventurous you can clamber across the rocks to a small sandy cove at the far end of the beach and this is a lovely secluded spot.
There are regular ferries to Bofin from Cleggan and it takes about 30 minutes. From the pier you turn right and walk for about 30 minutes; after the graveyard you will come to an opening and a sandy track which leads you to Duach beach. Just keep on past the entrance for Duach and you will arrive at the Bay.
