Like Rik, I don't know the current conditions but it has a few ups and downs that are a little steep. When skiing into that area I've taken the South Side trail that crosses John's Brook after 1/4 mile or so. It's a little steep getting down to the brook but pretty gradual as I think it's a jeep trail or something from the old days. It has only one spot that we found unskiable for our pathetic abilities. It is also more likely to have some snow on it and not be a "sidewalk". Of course if the brook is open forget it.The trails I've skiied (like the Garden trail)tended to be hard packed and too fast for my abilities and I've had good luck with skins and leaving them on up and down the hills.
