Pre-Covid, Denali NP had bear canisters for rent (or free loan?) then they didn’t when everyone was concerned about surface transmission of Covid. Maybe they do again?
Denali is never the wrong answer for one’s first Alaska trip. It’s more daunting than most other options because it’s all off-trail and there aren’t obvious loops or transits to make and the park personnel are famously vague in their suggestions (they try to disperse backpackers throughout the park). But if you’re ready to bash through the bushes and get your feet wet, it’s a fabulous destination.
In addition to a BPing trip there, I’d seriously consider reserving the park bus to Eielson Visitor’s Center and back (which could be part of getting dropped off and picked up for your trip – you’ll see more critters over those miles than in 4 days on foot (but animals seen on foot will really get your heart pumping).
I concur that if you can avoid paying $100+ per day to park a rental car in Denali, you’ll come out ahead. Also, the Alaska Railroad? Those observation cars windows are 20 feet above the terrain so you see A LOT more scenery than from your rental Kia Forte rental car. I’d definitely only make a cancel-able reservation because other options may well be better.
I’d suggest NOT bringing a pack raft on your first trip. 35F fast moving water and a lack of other people around makes packrafting in Alaska a whole different endeavor than 48-state packrafting. One little mishap and it’s suddenly a survival situation. Scout out rivers and ponder future trips, but also wade in up to your balls and you may reconsider.
There are definitely LOTS of things to do here on the Kenai Peninsula and if you want a sampler-pack of activities (hike on trails, raft salmon rivers, moutain bike, world-class canoeing, fat-tire on the beaches, day cruises for whale watching, get up above or onto glaciers, catch halibut and salmon, or get above treeline and then go and go off-trail for miles along the ridge lines).
If you want one, big, iconic backpacking trip and are feeling up the rigors of Denali, go for that. If you want to do a very different thing each day, or want a easy-to-moderate-difficulty long backpacking trip, then there are lots of options on the Kenai Peninsula and you can just GO. No permit. No reservations. No bear canister if you don’t want, etc. Or bring a .338 Lapua if you want (I woulnd’t). The only 20,320-foot mountain is 250 miles away (and visible in clear weather) instead of 20 miles away, and it IS very impressive from 20 miles away, but it’s rarely “out” in July – it’s usually cloud covered 25 days of each summer month and only out for a few hours on those lucky clearer days.
Post any Qs about the Kenai if that’s of interest. I’m off to teach math now, back later.
