Where abouts at Lake Champlain? There are many possibilities and Vermont is absolutely beautiful....i just love it there and have had some great times in the State.
I guess first and foremost is, having fun with the Beach/Lake! It should be fairly warmed up by then, good for toe - dipping and wading. Can the boys swim? Because anytime we have been near a lake, since I was *little* we got in boats and enjoyed simply being on the lake, maybe do a little fishing - perhaps a play pole for your little guy - or even just a peddle boat on the lake. You can also pack a picnic lunch and enjoy it on the lake. Playing in the sand - always a blast! There's the Ethan Allan II ferry boat ride you can take across the lake.
Also, there's hiking and bike paths that course along the contours of parts of the lake, romping in the woods - little boys love to find sticks and bugs, interesting rocks, maybe spot birds and butterflies. Also, one thing I remember doing was finding berry picking farms in summer - lots of fun!! The State parks have many options as well.
It's a GREAT summer destination, has some Revolutionary War history, a Jazz Festival in July and big 4th of July fireworks over the lake, visible from the beaches or on the lake. Endless possibilities!! Vermont is just an amazing state, you'll all love it!!
