My husband booked a half-day of climbing at Otter Cliffs for our honeymoon on MDI. We met Eli at the office, where he was super welcoming, checked out our gear, and got us on the road promptly. My husband and I have some climbing experience, but mostly in a gym for him, and mostly 15 years ago for me! Eli... More

Eli was an amazing instructor. ACS' professionalism far exceeded my expectations. It is no wonder these guys are considered on the cutting edge of the industry. Everything about the course, the way it was taught and the confidence it instilled in me was worth it. There are a few choices out there on who to take the SPI course with,... More

ACS and Eli gave me a day i would never forget. Very professional and a lot of fun. There was never a time where I did not feel safe. I learned alot of valuable information not just about climbing but also about the Acardia park and its animals. I would definitely go to ACS again the next time I go... More

We had such a great time that we have climbed with ACS for the past two years. Eli Simon, head of ACS and our guide, was absolutely spectacular. Our climb... More

Thank you ACS and Eli for a putting on a great SPI course and examination at Pinnacles National Monument!

Eli was very thorough and clear... More

What an amazing experience! This is a MUST do activity for anyone visiting Bar Harbor! The guide we had is an incredibly experienced climber and very knowledgeable about the area! My fiance and I will definitely be going climbing again!

I wanted to do something adventurous with my family (wife and 8 and 11 yr old boys) and this was perfect! Our guide was knowledgable and calm and brought us to a great, picturesque spot to do some climbing. Everyone thoroughly enjoyed this trip!

This is not just beginner stuff, you must be in decent shape. I consider myself in "ok" shape and fairly athletic. THIS WAS AWESOME. I was totally scared out of my mind, but GRANT was such an awesome coach and instructor, he made the whole experience that much more awesome. My husband and I went to Otter Cliffs and had... More

This was one of the best experiences I've had in a long time. Our guide was amazing, having just me (53 yrs old, no experience) and my daughter (17 yrs old, no experience either) for a 1/2 day journey to Otter Cliffs. Our guide (Hannah) was terrific, patient, and had us climbing and descending all morning. Our only regret is... More
