Preface: I did not make it all the way to MacGonagall Pass. I had originally intended on hiking to the pass, but due to inclement weather and time we did not make it.
Unit 20 is a thin slice of backcountry that starts at the McKinley Bar River, just south of Wonder Lake, and extends all the way to the Muldrow Glacier. It is the original and current informal climbers trail to routes on the north side of Denali.
The journey begins with a bus ride along the park road, nearly five hours and 85 miles later, ending at Wonder Lake. This would serve as day three of our eleven day trip. Were I to do this trip casually by itself, I would probably spend the night at Wonder Lake, then get an early start on the trail the next morning. Riding the bus for five hours is more taxing then hiking for ten, to me at least. I'm exhausted when I get off that bus. Warm dusty days are no different from damp dreary days- I'm not usually ready to launch into an immediate trek stumbling off the green bus.

Whenever you do decide to start your trek, walk about 3/4 of a mile back up the park road, then make a right onto the McKinley Bar Trail. This "family trail" winds about 2.5 miles mostly downhill to the McKinley Bar River.
Upon mentioning traveling in this unit, the Rangers eyes grew wide and wearied. Justly so, the Bar River can be treacherous to cross. She was quickly reassured to hear we planned to use packrafts. They generally talk most travelers out of this unit that haven't planned accordingly, or have avid experience crossing braided glacial rivers.
On the way out, we crossed the river in the widest spot, being almost over a mile wide here. Looking across the river, the tundra slowly rises in the distance. A rounded hill, named Turtle Hill, sits just upstream from where the trail intersects with the river. This is a good landmark to target in the distance. In total, our crossing going out resulted in about 8-10 ankle deep crossings, 4 knee-thigh deep crossings, and 1 main channel crossing which we inflated packrafts and ferried across.

Once on the far shore, we enjoyed the benefits of our friend, the sun. Drying out gear, changing into dry clothes, and cooking dinner. By the time dinner was done it was about 8pm. I planned to walk for about an hour, then camp, but the tussocks had different plans for me...
I've read numerous reports about an informal climbers trail heading south from the bar river, we didn't find it until reaching Turtle Hill. Thus, we spent over two hours hurdling our self from tussock to tussock trying to climb uphill- it was exhausting. My only advice is be prepared for the same. This is one place I wish the park service would suck it up and establish a trail. The informal climbers trail is actually a historic trail, having been used by many of the pioneers of Denali. It could be a treasured landmark, established accordingly, as much of it already exists, then maintained seasonly by experienced backcountry backpackers and climbers wishing to use the traditional routes to the mountain- instead of the more contemporary method of approach via fixed wing aircraft.
After stumbling between tussocks while swatting millions of flies swarming up from below- we found a nice clear spot to camp. This was probably the first and only piece of flat tundra, until Turtle Hill, able to host a tent. Sunrise came early and brought a swollen hot sun to the east and a brilliant Denali to the south west. Each equally filling our tent doors on either side at 7am.

The only thing I hate more than mosquito head nets is mosquitos...
We would later hear Rangers and bus drivers describing the past 36 hours as the past views of Denali in five years. It was certainly the closest we had ever been to this awesome mountain. I have no problem lingering over a long breakfast when you have views like this.

I don't really have an ethical stance on leaving gear stashed in the backcountry. Normally, I would probably say carry it because you don't know when you'll need it. But, in the moment, we said screw it, leave it. Atop Turtle Hill we decided to stash our packrafting gear behind this large lone rock. Dropping paddles, dry bags, PFD's, and boats saved about 8-10lbs in our packs. It doesn't sound like much, but it sure felt great. In my opinion, the gear was scentless, so there was no risk of animals bothering it. I don't think anyone had been in unit 20 lately, so we weren't concerned about it being tampered with or inhibiting someone else's experience. And two days later, it was still there.
Several miles back into the valley above Cache Creek, we came upon this small beaver pond. One lonely beaver was continually making laps around this swimming pool sized pond. His small muddy lodge on the far side, he kept swimming figure eight shaped loops around the pond, ever so often slapping his tail and diving under the water.
The highlights of our hike can be seen in this quick little video.
When the weather turned soggy, so did our aspirations of achieving the pass. We camped about four miles from the actual pass. Continuing would have meant descending from a nice knoll we camped upon, to travel back into the Cache Creek valley and ascend at least another two thousand feet. The return hike took us about eight hours to hike 12 miles back to Wonder Lake. On the return trip across the Bar River we crossed about a mile further up river. The river here was much narrower and had just four main channels which we ferried across with our packrafts. I made the mistake of thinking the third of four crossings wasn't dangerous, and attempted to walk across. Making it midway across my feet quickly were flushed out from beneath me in chest deep frigid water. I was able to lunge for my boat washing briefly downriver before my feet caught rock again and I could flop onshore. Lesson learned, if the packraft is inflated, and you don't know the rivers depth, just use the boat.
This three day hike into unit 20 wetted my appetite. I'm not sure how soon I'll be back, but I will be back. Maybe a trek and climb will be in the future...
