Frogmore is not very big - you can walk around.
In the village, you should try to visit the bridge over the creek head at sunset. The creek lies on an east-west axis and the colours and reflections on the water can make for some rather stunning images.
There is a Regatta during the summer - around the first or second weekend in August. A variety of boat based races are followed by the race across the creek - through the tidal mud. Amusing to watch or take part in!
Take part in the race across the creek at the regatta. Launch a boat at the public hard at the head of the creek.
Pasties and other assorted pastry treats from the Post office and Bakery. Frogmore pasties are a proper meal in themselves and the jam doughnuts are equally good.
See what to buy.
The Globe Inn serves a variety of decent beers, both local and exotic.
The Globe Inn has accommodation and there are a few B&Bs in the village, one or two with very nice views of the creek that you can wake up to.
