About us

We were founded in 1974, and have been guiding rock and ice climbing trips in the Gunks and Catskills Mountans for more than 40 years. We became an American Mountain Guides Association (AMGA) accredited guiding service in 1986, when the accreditation program was established.

We work with clients with wide range of abilities and experience - from total beginners, introducing them to outdoor rock climbing, to avid climbers visiting the Gunks from other regions and interested in climbing the Gunks classic routes. We help organizing group climbing trips - corporate outings, family retreats, adventure groups. We have extensive experience working with kids - during school breaks, we guide rock climbing outings for summer camps and boy scout groups.

We also offer a wide range of climbing programs - we teach rock climbing techniques, rope management and anchors, multi-pitch, lead climbing and more. Additionally, we organize customized programs, based on your abilities and goals. We bring 40 years of high professionalism and safety.

Bob Ferrari

Chief guide and Owner

“I have been fortunate to have spent the last 23 years of my life climbing at one of the Northeasts most pristine climbing areas, The Shawangunks mountain range.

For the last 14 of those 23 years I have had the privilege of working as a guide for the longest running guide service on the Mohonk Preserve, HighXposure Adventures Inc., formerly High Angle, founded by Jon Ross in 1974. We are proud to say that we're celebrating our 45th year of business. The last 19 years that I have spent guiding here have been some of the most rewarding years of my life.

As your ambassador to the "Gunks" it's my aim to make sure that every HighXposure client has the best possible climbing experience of their life. I truly enjoy meeting new people, sharing my climbing knowledge, and showing you all the beauty this wonderful area has to offer. I look forward to climbing and guiding here for many more years to come.”

Lead Guide, AMGA and PCGI certified multi-pitch rock climbing instructor

“Back in the day, I used to teach public high school in Philadelphia. During the summers I was part of an Adventure Based Counseling team that worked with inner-city High School students. Rock Climbing was one of the many venues we used to mentor and develop these young teens. I became obsessed with the sport.

I was so infatuated, that I left my job, got rid of all my positions, packed up my little car, and headed to New York, specifically the Gunks. I moved into my tent and began living the dream! I started guiding fulltime in 1998. For the next 6 years I spent my winters guiding in El Potrero, Mexico and the rest of the season guiding at the gunks. I have guided and climbed all over the country and have had the opportunity to spend a month in France on two separate occasions.

I love teaching and I love climbing. How fortunate I am to share my passion with others! I love taking out beginners. Sharing the experience of someone's first time on rock, first time doing multipitch, first rappel is completely gratifying and exciting. My delight at other people's discovery of Rock Climbing confirms that I am leading the life I was meant to live. Alright, I know it sounds corny but it is true. My philosophy on guiding is to teach technique and skills that allow the climber to work their way up a route making their own decisions and solving their own puzzles.

In 2005 I began working fulltime at The United States Military Academy. I work in the Department of Physical Education teaching Rock Climbing and Military Movement. I am also the assistant coach of the USMA Competitive Climbing Team, and the coach of the West Point Recreational Climbing Team.

I am passionate about my job. I am blessed that every single day, I have the opportunity to teach, inspire and interact with the future leaders of this great country.”

Bob Hostetter

“Since 1988, when Jon Ross brought me into the fold of HighXposure (formerly High Angle Adventures), I have been guiding rock climbers on the awe inspiring Shawangunk Ridge.

I started climbing in 1984 after enrolling in a Phys Ed course at a local Community College, and was introduced to this unique mode of existence by Rosie Andrews and Rich Goldstone, who were our guides that weekend. Soon thereafter I relocated to Gardiner, NY to continue my education at the Shawangunk Hard Rock University.

In 1986 I was fortunate enough to have been offered the opportunity to work as a Ranger for the Mohonk Preserve by Thom Scheuer. I strive to follow Thom's example regarding the protection and promotion of the mission of the Mohonk Preserve, it's history of land stewardship, and it's rich tradition of which rock climbing has always been an important part of.

I continued to work for the Mohonk Preserve until I began my career with HighXposure. Jon Ross and I worked together for almost 20 years as High Angle Adventures, and although Jon has, for the most part, hung up his rack, I hope to continue working for at least the next 20 years with Bobby Ferrari, and the rest of the awesome crew at High-Xposure Adventures. We would all be honored to have you climb with us soon!”

Dale Storti

Dale was first exposed to rock climbing while at summer camp in the Catskill Mountains. He signed up for a climbing trip to the Gunks and was immediately hooked. Since then, climbing has become a priority for him; competing in competitions as a teenager, travelling across the US and Canada to explore different environments and rock types, and now working as a guide in the place he first discovered climbing, the Gunks. He loves introducing people of all ages and backgrounds to climbing and hopes to help them have an initial experience as magical as his. When he is not guiding, Dale enjoys exploring the woods for unclimbed rock with his dog Esme, cooking at home, or going to live concerts. He is an AMGA certified Single Pitch Instructor, NYS certified guide, and Wilderness First Responder.
