If you want a medieval experience on your trip to Ireland, escape to Killarney. Inside the Killarney National Park you will find enchanted forests and a virgin nature surrounding the highest mountain on the island: The Carrantuohill just over a thousand meters high.
There are tours that can be easily hired from the city of Killarney. They perform the famous Ring of Kerry - Kerry's ring - in a circular circuit through Kerry County. Everyone leaves from Killarney by taking a tour that includes Kenmare, Sneem, Caherdaniel, Waterville, Cahersiveen, Kells, Glenbeigh, Killorgin and back to Killarney. All coaches make the same route and in the same direction since the road is narrow and in summer real collapses are formed. It is ideal to do it by rented car to enjoy the places and stop as you wish.
Among other wonders that Kerry hides is Ross Castle. It is located inside the Lake Leane very close to the same town of Killarney. It was built during the fifteenth century by the can of the O'Donoghues and it is the last castle that resisted the onslaught of Oliver Cromwell.
You can easily visit on a pleasant walk from Killarney. It is located inside the national park and the lake is surrounded by thick forests where one enjoys nature in the state. Inside one can visit the rooms and during the summer there are boats with which to navigate the lake and even reach the island of Innisfallen.
I recommend visiting Ross Castle after six in the afternoon, when people leave and the sunset offers the best photographs of the place. Ideal to take a sandwich, a beer and enjoy an authentic Irish fairy tale.
This area has a good tourist history behind it and in the heart of Killarney you will find a few hostels where you can sleep at about 15 euros per head.
