Fields Corner, red line. The corner itself is not especially beautiful but there's good Vietnamese food. Walking uphill on Adams Street takes you to Ronan Park with views over rooftops and harbor. A walk from Fields Corner through Wellesley Park, Melville Ave, Tremlett Street gives you a nice tour through a beautiful residential area built up around 1900. Continue on to Washington Street-- you'll find roti and other West Indian treats along Washington by Codman Square.

Savin Hill, red line. Walk over the bridge and all around the gorgeous and cute neighborhood there with beaches, beautiful houses, hilly streets and hilltop park in the middle.

Ashmont, red line. Jamaican restaurant right there, Ashmont Grill is still open but maybe shutting down. Beautiful neighborhood on Ashmont Hill-- Ocean, Alban, Mellen, Harley Streets. Or walk through Carruth, Beaumont, etc. over to Adams Village for the Greenhills Irish bakery and more cool stuff. Or take the Mattapan trolley to Milton, check out the Baker Chocolate works area there along the Neponset River in Dorchester Lower Mills. Or stay on the trolley to Mattapan with its Jamaican, maybe Haitian treats plus the locally famous Simco's over-the-bridge. No fare on the Blue Hill ave buses back to Ruggles (thanks to Mayor Wu.)

Green line "D" Riverside cars to Newton Centre. Nice area, pretty, rather upscale many shops. Then walk along Lake Ave by Crystal Lake (where you can swim in the summer time.)

Green line Riverside to Chestnut Hill. Walk up Hammond St or Chestnut Hill Road through a super swank residential area to the Chestnut Hill Reservoir-- very scenic -- then back to town on the green line "B" streetcars along Beacon Street.

In Jamaica Plain, the pond, the 'pondside' neighborhood between Centre St and the pond, various other neighborhoods along Centre St plus all its shops and cafes, the arboretum, Dominican food near Hyde Sq or Egleston Sq, Franklin Park.
