What Old Mountain is all about:
Transforming
Adventures that stay with you for life.
Inspiring
Sparking curiosity and cultivating wonder.
Grounding
Connecting with people and place.
Your guides along the journey.
Jesse and Trevor Borden grew up in East Africa, ended up in California for university, and have spent their lives moving comfortably between both worlds. They understand what it means to dream about Africa from a distance — and they understand Africa itself in a way that only comes from growing up inside it. That combination is rare. It's the whole reason Old Mountain exists.
Jesse is a conservation ecologist with a PhD and over a decade of leading expeditions across Tanzania, Central America, and beyond. Trevor has been organizing and guiding people in East Africa since he was 19 years old. Together, they bring the kind of knowledge you can't find in a brochure — and the kind of care that makes you feel like you're traveling with family, not a vendor.
When you travel with Old Mountain, you're not handing your trip to a company. You're handing it to two people who have wanted to share this place their entire lives — and who will make sure you come home knowing you did it right.

This journey reflects what we love most about Africa: being out in it up close, on the ground, under the stars, and falling asleep to the sounds beyond the tent. It also celebrates Africa's beauty from extraordinary, deeply comfortable places. We partner with Dorobo Safaris because they are rooted in this landscape and lead with a rare balance of expertise, respect for local communities, and genuinely soulful guiding. Together, we've curated the full spectrum - from tented walking experiences and community connection in the Manyara ecosystem to epic lodges, vast vistas, and unforgettable sundowners - so guests feel the true breadth of Africa.
Specific itinerary details are subject to change based on availability, travel dates, and group size.
