Our Team

Yosemite Guide Service Team

Our Guides/Summer Camp Counselors are the key ingredient to success for Lasting Adventures. Although we all come from different backgrounds, we all share a passion for Adventures, Yosemite, and sharing it with others in a way that will create memories to last a lifetime. Our Yosemite guide staff is a young and energetic group who all understand the importance of professionalism, caring, and risk management. Some of our guides have grown-up in the program having started as a youth participant themselves. While others have been selected for the backgrounds and experiences they have with youth and within the outdoor environment. It’s common to have guides with off-season jobs of being a teacher, naturalist, counselor, or other youth professional. Many of our guides reside in the sierras year round. On most trips you will get the privilege of meeting more than one guide.

Our guides come together for a week long staff training each year. We bond as a team through fun activities, setting goals, and debriefing. This is essentially the same Adventure Based Programming model we facilitate on our youth, group, school, and corporate adventures. Our staff training week also covers Wilderness Ethics and Leave No Trace Principals, Risk Management and Emergency Protocols, Yosemite History, Positive Youth Development, and the basics for providing outstanding customer service in the back-country. Through the connections we create during our staff training, and also through their shared passions, it is common for our staff to spend their off-time together (usually in the Tuolumne Meadows vicinity). During the summer our team works, lives, and plays together!

On every youth trip (not exceeding 12 participants) there is a ratio of at most 1:6, but in most cases the ratio is 1:4. Each trip will also have at least one male and one female Guide/ Counselor as necessary.

Through our Guide Service, on day trips and backpacking trips, we will staff each adventure with 1-2 experienced guides who bring with them significant Yosemite backcountry experience. Ratios will not exceed 1:6; usually less.

Every leader has, at least, certification as a Wilderness First Responder and C.P.R. All leaders have also completed an extensive background check including criminal history.
