In most of NH, you do that in your back yard. You don't need to drive somewhere to do it.
As for driving, from anyplace in NH, you're never more than an hour or two from, mountains, lakes, shopping, or the ocean. What's chances we could drive to the ocean for a day at the beech and have dinner at a nice restaurant in the mountains, anywhere in Wyoming, Montana, or Idaho? everyplace has its advantages and disadvantages, still NH is definitely not for everyone. There is no place like that.
If you're not too insistent about your beach having an accompanying ocean, you can do that right here in Utah :-)
