Great for spotting seals! also an old bicycle down there which is a bit of fun. Really easy to enter the water, you can walk down the old life boat ramp. Best go when the swell isn't too rough.

Park behind the gardens at Gyllyngvase Beach and make your way around to the south end of the beach. The Ponus wreck is on the southern reef about 70m from shore. You have to cross the reef or swim around it to get to the wreck. Gyllyngvase Beach is also known as Ponus wreck.

South reef slightly deeper with more life, north reef shallower but there is an open arch to swim through at high water. A very easy shore dive. Very easy access, park in the carpark for just £2 and get a free cup of tea! You can't miss the sea :)
Pendennis Point

#7 - Pendennis Point

UK, England, South West

The first gully contains the remains of a German WWI U-Boat, the UB97. There is not a lot left but it is noticeable by a large '3 pronged fork', most of the wreck is quite flat. The second gully has the remains of UB86. There is quite a lot left of this wreck and it stands 3m high at the highest point, it can be spotted in 2 of the photos on this page. Spend some time here looking under the kelp, it is quite big and full of life. The third gully has a narrow and very scenic route, it winds it way quite shallow before it stops about 6m into a tiny cave. Drive around Pendennis Point along Castle Drive. Go past the car park at the point about 400m and park in the layby. To the left of the layby there is a path, the path splits in two, take the right hand path down the Silver Steps. Entry is best at high tide, low water entry is tricky and not recommended. There are quite a few for the return journey, the handrail is not as strong as it used to be. Pendennis Point is also known as Silver Steps.
Maenporth Beach

The wreck can actually be seen in the Google maps image above, at low tide you can walk around it. A bit of a swim but very interesting once you're there. A 422 ton fishing trawler that came ashore in the 1970's. Maenporth beach is at the southern end of Falmouths beaches. Car park is on the beach. Enter on the north side and follow the reef. It is a long swim out to the wreck, in fairly shallow water but it is an easy dive. Maenporth Beach is also known as Ben Asdale.
