Derry~Londonderry is the Gateway to the Northwest,  it's the central hub for exploring the following:

1. The Wild Atlantic Way

The world's longest defined coastal touring route. It's inspiring, renewing, relaxing and invigorating. It's yours to  
experience however you choose.

2. The Causeway Coast

The majestic Atlantic coastline that sweeps eastwards from the Foyle Estuary to the Giant's Causeway and a must for all visitors is a trip on one of the World's Great Railway Journeys as detailed by Michael Palin in his rail journey from Derry to Kerry, the Sperrins Mountains (An Area of Outstanding Natural Beauty AONB) with its world class Ulster-American Folk Park, are well-known to nature lovers.

The Inishowen Peninsula has been relatively unexplored by overseas tourists until recently - it really is one of Ireland's most delightful secrets, so you have a treat in store. Here are a few suggestions for things to see and do on a day trip across to Donegal from Derry:

1.  How about a bracing stroll on the sand of the surf-washed Blue Flag Beach at Culdaff.
2.  A walk up to the awesome Gap of Mamore
3.  Or a sea-angling expedition aboard a top-class boat from Bunagee Pier.
4.  A visit to Ireland's most northerly point Malin Head.  
5.  Don't miss very welcoming Doagh Island Visitor Centre which tells the story of Famine, fear and Eviction in a superb       
      setting. Its cottages preserve the customs, traditions and history of the people of Inishowen.  Scenes include a Mass   
      Rock, Presbyterian Meeting House and Orange Hall.
6.  Then how about an afternoon of seaside fun in Buncrana.
7.  A day's pony-trekking around Muff.
8.  A leisurely seafood lunch in Greencastle/Moville.
9.   A guided tour of Fort Dunree, Ireland's only military museum.
10. Watch a performance of spectacular culture at the Cairn Visitor Centre near Greencastle.
