5 Best Activities In Isle Of Portland
Portland Castle and Portland Museum carry the indoor side of a five-entry island list, and Portland Bill Lighthouse is filed with them as an indoor visit. Outside, there is Easton Gardens and Moonfleet Adventure Sailing, which is as weather-dependent as it sounds. Three in, three out, with the castle counted twice — a small list, but a varied one.

A museum, two historic sites, a garden and a boat is enough for a day rather than a week. The castle and the lighthouse are the entries that hold a child's attention longest, and both are listed with indoor space.
Visiting Isle Of Portland with kids: FAQs
The wind is up. What can we still do?
Portland Museum is the obvious answer, listed as indoor and unaffected by what the sea is doing. Portland Castle carries indoor space too, so it survives a rough day better than most historic sites. Portland Bill Lighthouse is also filed indoors on our data. Anything on the water should be checked with the operator, who will call it off before you do.
Where can children just run about?
Easton Gardens is the entry for that, listed as outdoor and the closest thing on the island's list to somewhere you can sit down while they wear themselves out. Portland Castle has outdoor space as well, which gives you the same effect with something to look at attached. Neither needs booking in the way the boat trips do.
Can we get out on the water?
Moonfleet Adventure Sailing is the entry for that and it is listed as outdoor, which in practice means the forecast decides for you. Sailing operators set their own minimum ages and require particular clothing and footwear, none of which we hold, so contact them directly and have a land-based alternative such as Portland Museum ready in case the day is called off.
