I found a deal for this place on Groupon and decided to make a day of it with my family. This is an indoor facility with two different rooms of walls. We climbed the walls for two hours and the staff were super nice, helpful and patient. There are many different walls to try out, the staff will know which ones are easier and suitable for your physical needs. I would start out thinking a wall was easy and then halfway up the wall I would realize how wrong I was. There are also ropes and ladders, a great place for the whole family.
We had six people, two different instructors were there to hold the ropes and guide us through the climb. I asked if you have to be able to climb all of the walls in order to become staff and the young man helping us out replied that it is not necessary but is useful because you can aid the customers, provide tips and make the experience better. This is definitely true because this guy can climb! He also knew how to get the most out of the wall and showed us all of the different obstacles that Of Rock and Chalk offers. Other then the two main rooms there are the boulder climbing that are smaller walls, done without the use of the ropes and staff members.
We had a great time and I will definitely recommend this place to anyone in the Newmarket area looking for an adventure.
