First off, you don't want to learn to fly in a mountainous region. The weather is often not conducive to training flights, and neither is the geography.

South Africa, southern Spain and the SE or SW US are your best and cheapest options. Your current residency will likely decide which is the best suited, given the Corona restrictions.

Do not rush the process, as you face a high risk of burning out. You should allocate around 2 to 3 months to the project, allowing for a natural pace and a relatively flat learning curve.

Find a reputable school and research the hell out of it before you decide. It's an expensive undertaking regardless of how you do, and quality of training and professional/experienced instructors is your best guarantee of being as well prepared as possible when time comes to plough your own furrows in the skies.

Find a school operating the most modern aircraft you can lay your hands on.

All the above is mainly for a PPL license. If you chose to go the LSA route, find a club close to where you live and go hang-out with the owners. See if there's an option of taking part in shared ownership in a group of people you can get along with. LSA flying is relatively inexpensive compared to PPL, but does come with a number of restrictions - mainly aircraft performance and being limited to taking only 1 passenger. For me, if the aim was only to fly for fun on sunny days with no ambition of obtaining an instrument, multi-engine or commercial license, not having a need to take more than 1 pax, and given the availability of part ownership in a nice aircraft in a nice club, I'd seriously consider the LSA route.
