When you visit the United Kingdom, you'll often be tempted with some amazing stretches of coastline, especially with the combination of stellar landscapes and ruinous castles found perched on cliffs in many a corner of Wales. One that is sure to leave your mouth agape is the Pembrokeshire Coast National Park. With about 75 points of interest, from volcanic rock formations to sweeping limestone cliffs to idyllic stretches of untenanted beach, this is our sort of hiking paradise.
The best way to experience this is through the Pembrokeshire Coast Path, a 300 km (186 mile) trail that skirts Marloes Peninsula, St. Bride's Bay, and provides so many epic views that you'll run out of space on your camera's memory card. There are options to jump on or jump off the trail at various waypoints.
In case you thought Pembrokeshire was all about the hiking, you'll find that this area of coastline is also great for surfing (Newgale and Whitesands in particular) and scuba diving, especially the shipwrecks and reefs around Skomer Island, Milford Haven, and Hooper's Point. We'd also be remiss as an adventure site if we didn't make mention of the coasteering phenomenon that all started here. Get into this if you'd like to combine climbing, swimming, and jumping in a new and exciting way. Check the official site for much more information!
