We visited Bowman's Hill Tower on our way to New Hope. It's right off Rt. 32 and easy to find. My wife and I and our two teenagers walked the steps to the top of the tower. There is an elevator but the steps aren't too challenging. The elevator does not take you all the way to the top but instead only up to a landing inside the tower where everyone has to take the final 15 or so steps to the top. This last section is very tight. Only one person at a time can get by.
The view at the top is worth it. It's easy to see up and down the Delaware River and it's a nice spot for pictures. There is a white aluminum fence at the top that detracts from the scenery.
We drove our car to the base of the tower. The road up the hill is narrow but not a problem in a car.
The admission fee is $5 per person.
It's a nice stop and it doesn't take long to see it if you're pressed for time.
