Just get a point and shoot camera. If you also need a GPS, you can get one of those TomTom devices they used to put in cars.
Dedicated MP3 players are also still a thing if you want a soundtrack for your life.
Now all you need is that sweet candy bar phone, throw all this in a large fanny pack and off you go.
PS: an old school wallet would also be useful, Symbian OS doesn’t have Apple Pay yet.
