we just take our lunch with us, plenty of nice spots to moor / anchor up all along The Menai, The Gazelle is nice to sit outside on a sunny day and watch The Cardinal Buoy bobbing about on its mooring
best place to see the dolphins is any where between the Caernarfon fairway buoy and Trefor, we saw them fishing over the Caernarfon Bar last summer, also spotted them off Sth Stack so guess you just need to be in the right place at the right time
on a nice day the Ty Coch at Morfa Nefyn takes some beating for a pub lunch or down to whistling Sands for a ice cream is a good day out too, oh and don't forget to stop off at Pilots Cove, I spent many a happy hour on the beach last season recuperating
we're based in Caernarfon too, at Ty Calch, best launch / recovery service in the world, but don't tell Chris
