Top-notch family destination.
If you live in Lancaster County or plan on visiting sometime in the summer time, I highly recommend you visit Lost Treasure Golf in Lancaster on Rte. 30.
I am sort of a miniature golf junkie. I have 3 kids, ages 4-17, who also really love it. Occasionally I drag the wife along, but she isn't really into it. This place really stood out from any other course or location I'd been at before. It's great!
Anyway, when we first visited this place last year it looked fairly interesting to me. I saw their ad in a magazine and decided to take the kids for a day. Boy, I wasn't disappointed! We all had a great time there! They have two different mini-golf courses and a maze where you can win prizes. Anyway, my oldest son and I preferred the Gold course while my youngest son and daughter liked the Diamond.
The service there is amazing too. All the employees were very friendly and helpful in our first "expedition" to their golf course.
Seriously, if you are going to Lancaster, PA any time during the year (except winter, when obviously they're closed) give them a call or just stop in. If you live in the area, look them up. I for one can tell you that you won't be disappointed!
