Regarding VR, and if you want to build yourself a nice online folio of your 360 content, these are just my 2 cents but perhaps you could use an online tool such as tourmake.it (which I've been using professionally for years, but many other exist) to import them and create an interactive menu allowing you to organize your 360° in categories (hiking | nature | spot 1 | spot 2 | etc..). It has the option to publish for free or with a paid license. It usually is dedicated to build interactive tours over Google Streetview 360 tours, but it also has a feature named Viewmake allowing you to upload directly your own 360 pictures, which in this case could match with your interests.
Then the online tour has an option to easily switch to VR mode on mobile phones, and navigate through with your VR headset (here's for instance one of the tours I published if you wanna try: https://tourmake.it/de/tour/f41a67a2761ed41b84806b991b31431e)
About Gmaps, if I understand it well, you know how to add imagery content to an existing location on Gmaps, but can't easily find it afterwards. If so, when logged in to your Google account, go to Gmaps and on the left menu section, go to "Your contributions". It is splitted between reviews, photos & modifications you've brought.
Edit: mea culpa, I realise now that Tourmake seems to be accessible to Streetview Trusted photographers only, and that they recently have changed something into their business model, it has a yearly subscription to access the software.
To be forgiven, let me just share to you the world's biggest panorama, shot in the Mont Blanc valley: http://www.in2white.com . 365 gigapixels, 70K pictures taken.
