I have...went there for my first visit during skinny dip world record attempt. Above ground pool, nice people, some open space and trails. Not upscale but not a dump either...prefer white thorn lodge in pa.
We have visited many fine clubs and even 1 in Newark that wasn't but we enjoyed Alpine the most. No Swinging. Family camping style. Some singles were there but no problems. Owners seems to approach problems with some finese. We have been to some better equipped campgrounds but NONE with as many friendly people as Alpine. We were made to feel very comfortable and people actually made an effort to visit and speak to us. There event schedule was absolutely full each weekend with family and children's games. We have been at about 12 other camps over 25 years and these people are truly GOOD people there. Oh yes, everytime we have been there there has been tons of food fixed by the owner and given away. Camps in other areas need to trek to Alpine and take lessons from them. Yes we will go back and might even join as members full time! Thank you Alpine for some nice visits!
