Truffle Pigs Lodge hosts 12 lodge rooms in tiny Field, the only community in Yoho National Park. If you want to stay in Yoho, this is the most affordable way to do it without camping. As a bonus, all rooms have incredible views.
The Family Suite and Queen with Kitchenette provide particularly good value for money. The on-site restaurant is excellent.
A Parks Canada parks pass is required to explore Yoho National Park ($22/day for a vehicle of up to 7 people).
