The ground floor hosts a spacious kitchen/diner where you'll have no problem cooking at home in the fully-fitted kitchen, with a breakfast bar and an extendable table for seven for everyone to dine together. Ideal for grandparents or those with limited mobility, you'll also find a ground-floor bedroom with a small double bed, storage space, and a wall-mounted Smart TV, as well as access to a Jack-and-Jill shower room. Unwind after busy days in the bright and airy, first-floor sitting room with a sumptuous sofa, Smart TV, Xbox, and a selection of books and games to choose from. Alternatively, open the French doors to find the enclosed, private courtyard to dine al fresco, sunbathe on the sun loungers, or play games on the AstroTurf.

Start your holiday by exploring the Isle of Portland, with Sea Gem set on a quiet, residential street in Castletown close to Portland Castle, Osprey Leisure Centre, and Portland Marina. There is direct access to the sea via a jetty next to the castle, and the coast path can be accessed just around the corner from the property. If you fancy a break from cooking, you'll find Chesil Chippie, The Cove House Inn, and a selection of cafes to choose from, with lovely walks or cycling along the coast and Rodwell Trail. For more family-friendly adventures, be sure to visit Fancys Farm, Tout Quarry sculpture museum, Portland Bill, and Portland Museum set in 17th-century stone cottages.

Alternatively, explore Chesil Beach and book a boat tour at Wild Chesil Centre, but if you prefer staying on land, the Jurassic Coast offers spectacular coastal walks as well as Dorset’s' countryside.

For a change of pace, the county town of Dorchester is a short drive away with plenty of history to uncover at the National Trust's Max Gate, the former home of Thomas Hardy, a selection of museums, and Kingston Maurward Animal Park and Gardens.

Area Details


Castletown was once the gateway to the Naval Dockyard. Today it is the hub of a vibrant area with a thriving leisure and watersports industry. Portland Marina itself has 560 berths. Weymouth and Portland National Sailing Academy offers tuition for windsurfing, sailing and kitesurfing from beginner to expert. You can find a wetsuit and drysuit shop with chandlers and one or two places to purchase a yacht. Whilst all this new development has gone on, the history of the area has thankfully remained. Portland Castle, built in 1539, is in the heart of Castletown. This is an artillery fort constructed during the reign of Henry VIII and now run by the English Heritage. The Castletown D-Day Centre has been running since 2017. It is the number one attraction on Portland giving a perspective to the D-Day landings with a Sherman Tank and full-size Spitfire. Portland Harbour is on your doorstep and a strenuous walk up the hill will take you to the High Angle Battery. Eat out locally at the Cove Inn and watch the sun go down over Chesil Beach. Quiddles Cafe also enjoys views over Chesil Cove or try The Boat That Rocks for views over the Marina.
