Camping permits are required for those staying overnight in a developed campground, backcountry campsite, yurt, ranger cabin or similar. Visitors with a valid overnight camping permit do not require an additional day-use permit for the same period.
I have used Algonquin Portage services several times a year since the early 1980s. Their service is always excellent, timely and professional for equipment rentals, drop offs and supplies. I found that they have made access to the interior of Algonquin Park much easier!
