Adirondack Trip Planing

Finger lake any of these. The size of your rig may limit you to some sites in the parks
Watkins Glen State Park
Sampson State Park - this would make a good one to do day trips to check out the wineries and the Finger Lakes
Keuka Lake State Park
Cayuga Lake State park

Corning Glass museum

Lake Placid area - we like - - http://www.northpoleresorts.com/100-acre-woods/

Fish Creek- Rollins pond DEC campground. Hiking, canoeing, kayaking

Drive across Canada and check out the Niagara Falls area.

Come visit Ausable Chasm where we camp, lots to see and do. Many great restaurants just north in Plattsburgh and you can take the ferry to visit Burlington (Vt).

We are using the Lake Placid KOA as a base in August. Although we won't be in the area as long as you, we plan on going to Lake Placid, Ticonderoga, Stowe, VT, Whiteface Mtn, and a day trip into old Montreal.

For first-time visitors you should visit the Adirondack Museum in Blue Mountain Lake. If you get to Lake Placid there's the Olympic venue, ski jumps, and bobsled run.
We're not into the Lake George scene, but prefer more rustic DEC cg's. For a full hookup, pull-through site there's North Pole Resort (100 Acre Wood side) in Wilmington outside of Lake Placid. You'll follow the Ausabe River, a big fly fishing stream.
From NE Pa I'd probably go north on I87 and hit the Finger Lakes on the way back. Letchworth SP has the Mt Morris dam and Genesee River gorge. Watkins Glen has a nice gorge walk. There's also the Corning Museum of Glass and numerous wineries to visit. There's a brand new cg being built (Twilight on the Erie), check out their Facebook page. They should be open by September.

I don't know much about the Adirondacks but here is my tip:
If you happen to be in Lake Placid. Go to the 46 sandwich place. By FAR the best sandwich in have tasted in my life.
Also for cycling around that area look at Ironman lake placid website for the bike map. 70km loop. 90km with the out-and-back. 2 loops and 180km for the full experience :) The way out is a steep descent and the way back is a long but relatively easy climb following the river with good scenery.
