I rarely go to Jamaica Plain (also known as JP). Since moving here, I've only been 3 times, all to volunteer at the same place. This Sunday, since neither Josh and I were working, we decided to head down to JP and check out the Arnold Arboretum. We drove there, but it's easy enough to get to via the T; just take the Orange Line to Forest Hills and it's about a 5 minute walk from there.
I was pleasantly surprised to find out that the Arboretum isn't packed with tons of people, making it a welcome alternative to other outdoor spaces such as the Boston Common. I highly recommend checking this place out if you want to spend a lazy afternoon in a beautiful space.
There are quite a few flowers still in bloom and tons of honeybees. We even saw the head of a massive turtle as it came up for some air. There is a bonsai exhibit but we missed it because we didn't get there until after 4 pm.
