But we'd managed to reserve a campsite that was on higher ground, so we weren't entirely miserable. The campground had a large blazing fire in its main lodge. We sat in front of it, dried our socks and raincoats, and ate toasted marshmallows.
You can walk to the beach from the campground, even with small children. It is not a short walk. You do have to cross two streets, but otherwise the trail is mostly through pretty woods. It is a very nice beach. Not too bad in the rain, depending on your stamina.
The people at the front desk were friendly, though strict about the rules. After you check out, they won't let you leave your car in the parking lot while you go to the beach one last time.
There was a playground, which the kids loved, and a store, which the kids loved, and there were ping-pong tables in the lodge. You could borrow ping-pong racquets from the store.
The campground was not far from a Stop & Shop, for restocking groceries.
The bike path was very close to the campground as well. With teenagers, you could probably bike to Provincetown. But that was beyond the range of my children's capabilities.
You definitely want to take your bike to the Cape. The bike trail was beautiful, and relatively flat.
My husband thinks that walk-to-the-beach is a trap because, unlike the previous year, we didn't often drive to the other wonderful beaches in the area. I would rather not climb into a car if I don't have to.
I could see going back there to spend a relaxing week riding the bike trail, walking to the beach, playing ping-pong, and sitting in the lodge catching up on writing and reading. There was even a small adults-only lounge. (Not in the X-rated sense, but in the sit-and-read-in-peace-and-quiet sense.)
On the way home, stop by the Truro Vineyards and pick up a few bottles of the local grape for the folks you left to take care of your pets while you were away, and as a little bit of vacation to drink once you've been back in the real world for too long.
That was our plan, but unfortunately, we left on Sunday, and they close early on Sunday. We didn't get there in time.
If you're looking for a semi-rainy day activity, the winery also gives a free tour, which my husband and I found fascinating, while our children were bored out of their skulls.
