Very few places with short walking distance to the beaches in the south, as Steve say, the sea can be rough sometimes in January. I would like to add something about the beaches for you.
Own by the Government, you have to pay a small fee per person, 1-2 life guards on the beach, very safe for small children as the water is shallow and protected by a reef, but there are many small coral peaces in the water. The water is warm as it´s shallow and therefore not clear. One side of the beach has little breeze, the other (against Bucco) has more.
But the beaches are more and less natural, by that I mean that you will find coral peaces and sea grass nearby the water, the windy side has more sea grass. Don´t expect a totally cleaned beach as you find in Europe. Restaurant and some local shops but less compared with Store Bay Beach, toilets and showers of course.
And of course, even if the water is shallow, one must never leave the children alone on the beach.
Store Bay Beach;
Public area, no fee, 5-6 life guards on the beach, this beach has better sand compared with Pitgeon Point, no stones and sea graas. This beach isn´t protected by a reef so the water is very clear and not so warm as Pidgeon Point. The water get deeper quickly but it´s still safe for children as they never shall be alone, the life guards use be strict about that. Children love to dig and build in the sand. Beach bars, some shops, many places with local food, public toilets and showers 1TTD per person.
There can sometimes be lot of peoples on the beach, but never as crowed as a touruíst beach in Spain, never. But I still prefer Store Bay compared with Pidgeon Point.
Canoe Bay Beach;
Private area, you pay a small fee per person, on the Atlanric side but very quiet and very safe for children, very shallow water. Mostly you have to walk 75-100m out if you want deper water. But the road down to the beach is very bad as there are a lot of on-going constructions on the way down. Very little sand nearby the water for children to dig/build.
I must say I´ve never been there, if we are talking about the beach on the Atlantic side, if so; I believe it´s more a local beach, no public areas as far I know (stores, bars toilets and so on). Has any other comments about this beach?
Using a car you should also see Black Rock Beach and Arnos Vale Beach on the Caribbean side (for snorkeling). On the Atlantic side you have Bacolet Beach nearby Scarborough, there´s a beach bar own by the hotel. The sand is hard and very dark, no sun shairs for hire (only for the guests from the hotel). The beach is not protected by reef or life guards, safe as long one never go outside the edges of the cliffs, children are safe nearby the sand on the beach.
If you don´t find pictures enough for these beaches on this website, I can send some of my own directly to you if you give me your e-mail address.
