Overlooking four miles of sandy beaches, this mansion on the Llyn Peninsula is a spectacular choice for large family gatherings or a getaway with friends. Spread yourselves out on the terrace and grill up a feast on the barbecue while the kids run wild in the garden. The panoramic views across the water are simply incredible, and there is plenty of coast and countryside to explore on invigorating walks or bike rides. Adventurous types can also explore the peaks and valleys of nearby Snowdonia National Park, before coming home to soak their muscles in the outdoor hot tub. You could even book a massage or beauty treatment for your stay. The games room is a welcome distraction on rainy days, where you can get competitive playing air hockey, darts and table tennis. There are also two sitting rooms, for quieter times relaxing with a good book or toasting in front of the wood burning stove.
