The advice we received was that we should find a site by 1:00-2:00 p.m., so we thought we were ahead of the game when we were looking for sites by 11:30-12:00. We started at one end of Disappointment Lake and every single campsite was taken until the very last one on the lake by the portage to Ahsub Lake. We were getting very nervous we wouldn't find a site, as Ahsub Lake only has two sites and then there are no sites for quite a while. We lucked out and found a site.
We stayed there both nights of our trip. On day two, we took a day trip to the falls at Gibson Lake. Well worth it, they were gorgeous! It was a pretty easy trip there too as all of the portages are very short and are pretty good.
We had originally planned a 3 night trip, but decided to end our trip a day early. Our third night we were going to camp on Snowbank Lake, but weren't feeling it. We didn't want to be rushed to get home on day four, and weren't feeling the site as Snowbank Lake also has motor boat traffic. Didn't feel the same with the motor boat traffic.
Great trip, looking forward to trying a different entry point next time! Will do some things differently: 1) We will invest in our own packs to make portaging easier, 2) Get a better pulley system for hoisting the food bag, and 3) Better thermarest pads.
Look forward to making this a yearly tradition!
