There are many easy-to-use cameras available. Some allow more advanced uses, if you wish to do so later.
First decide if you want a compact camera with a non-interchangeable lens.... or if you would prefer something a little larger that uses interchangeable lenses, is more versatile for future "growth" and quite possibly has higher image quality potential.
Next decide how much you want to spend.
Speaking for myself, I'd choose an interchangeable lens camera (ILC). I'd want the option to add more lenses and be able to adapt the camera for different purposes. Also, most ILC use larger sensors that make for better image quality.
There are two major types of ILCs: DSLRs ("digital single lens reflex") and so-called "mirrorless" (MILC). Each of them have their advantages and disadvantages. DSLRs have been around for a while now... about 20 years... plus they are "descended" from 35mm film SLRs which had seen a half century of popularity, so are pretty thoroughly developed. Mirrorless were the "next new thing" around 6 or 7 years ago and have been quite popular... but so far there have been fewer lenses and accessories developed for them, and due to their popularity, their prices haven't seen much discounting. Mirrorless can be smaller and lighter, but often use smaller batteries and draw more power (with electronic viewfinders or constant use of an LCD screen), so get far fewer shots per charge. You'll likely need more spare batteries with a mirrorless camera. I recently took over 6000 shots at an event with two DSLRs, each of which is fitted with a grip that accommodates two batteries. I did almost the whole shoot with one set of batteries (four total), so I got about 1500 shots per battery. Many mirrorless only get 300 to 600 shots per battery.
I shoot with Canon gear and am most familiar with it, so will give you some examples based upon my own experiences. You can probably find similar in other brands.
Non-interchangeble lens cameras:
Canon offers several high quality non-interchangeable lens, compact "point n shoot" cameras with their Powershot G_X-series models. Some of these use a 1" size sensor that's fairly large for this type of camera, although it's smaller than most DSLRs use (

The larger the sensor, the better overall image quality is likely to be, especially when shooting in lower light conditions. But, the larger the sensor, the larger the camera and the less wide ranging the zoom lens will be. Canon also offers a number of of "ELPH" and "SX-series" Powershot "point n shoot" cameras that use a much smaller 1/2.3" sensor, which allows them to be more compact and/or to have wider ranging zoom lenses. The ELPH series are particularly compact... even "pocketable". Some of these are also quite affordable.
Interchangeable lens cameras:
DSLRs are Canon's forte (though they are rapidly expanding the mirrorless they offer). Their well established DSLR "system" includes roughly 90 available lenses and they offer some 13 or 14 different models currently. We'll quickly narrow those down, though. First, for travel and general purpose, I'd recommend the APS-C sensor models. There are 6 of those to choose among.
The most entry-level, least expensive is the EOS 1500D, which is called the Rebel T7 in N. America. You can buy it with two lenses for around $500 US. HOWEVER, this camera is very basic, lacks some nice features that can be found on slightly more expensive models. The two lenses sold "in kit" with it are also "entry level". The EF-S 18-55mm IS "II" is somewhat plasticky and has slower, noisier autofocus... but can make decent images and has image stabilization. The EF 75-300mm "III" is the cheapest telephoto zoom Canon makes... and the worst. It uses slower, noisier autofocus drive, lacks image stabilization (which is arguably more important on telephotos), and doesn't have particularly good image quality.
For $200 US more (current sale price: $700 US), the Canon EOS 250D/Rebel SL3, is a MUCH better camera paired up with two MUCH better lenses. (The previous model 200D/SL2 isn't all that old, might be available for a little less, and is very similar. The 250D/SL3 primarily has some changes related to video.) The 1500D/T7 and 250D/SL3 share the same relatively simple 9-point AF system and both use the same 24MP sensor.... But that's about all they share. The 250D/SL3 has many features omitted from the more entry-level model. Some of them are very important... Such as a self-cleaning sensor, which the 250D/SL3 has, but the 1500D/T7 lacks. In Live View and Video mode, the 250D/SL3 has Dual Pixel AF which is much faster and better tracking movement than the old contrast detection focus method the 1500D/T7 uses. In fact, the entry-level model (and another even more entry-level model sold primarily outside the US) is the ONLY Canon DSLR lacking these features.
The EF-S 18-55mm IS lens bundled with the 250D/SL3 is the "STM" model that has faster, quieter autofocus. And the telephoto zoom typically bundled with the camera is the EF-S 55-250mm IS STM, which is better than the EF 75-300mm in every imaginable way. It's faster, quieter focusing.... it has image stabilization... it focus closer... and it has noticeably better image quality.
Possibly best of all for travel.. the 250D/SL3 is the smallest and lightest DSLR offered by anyone. In fact, it's only a few grams different from and slightly larger than many mirrorless cameras with viewfinders and using similar size sensor.

They can be nice travel companions, too, thanks to small size and light weight. But, as already mentioned, they will be more expensive than a DSLR kit... and since mirrorless are fairly "young" and still being developed, there are fewer native EF-M lenses available (but, with a simple adapter they CAN use all 90 EF and EF-S lenses made for the DSLRs). For example, the Canon M50 in kit with EF-M 15-45mm IS STM and EF-M 55-200mm IS STM lenses is currently on sale for $879 US. The M50 has an electronic viewfinder. The M100 model does not, and it's available in kit with the same two lenses for $599. (You need to use the rear LCD screen to compose images with the models that don't have a viewfinder.)
Both these mirrorless use essentially the same 24MP APS-C sensor that's in the 250D/SL3 and 1500D/T7 (as well as a number of other Canon cameras).

The camera does virtually everything else for you. With all but the simplest point n shoot (ELPH models), if you wish, you can take control of more things in the future, as you learn how to use the camera. In many models there's built-in assistance for beginners, such as a "Creative Auto wizard" that describes how different camera settings effect images. There also is a lot of support in the form of third party "how to" books and downloadable user manuals on PDFs, free from Canon websites.
As I said, you can probably find a lot of the same things in other brands. I'm giving Canon examples because those are what I'm most familiar with (and because it's good stuff!
) Nikon offers a selection of DSLRs, lenses and accessories similar to Canon's. They also offer a lot of choices of point n shoot cameras, but Nikon doesn't have any APS-C mirrorless like the Canon M-series. Pentax also offers some excellent DSLRs and lenses, though not as many to choose among as Canon and Nikon. They don't have mirrorless. Fujifilm, Sony, Olympus and Panasonic all offer a variety of mirrorless cameras and fairly large systems of lenses and accessories to use with them (though nowhere near what Canon & Nikon offer for their DLSRs). I really don't know much about point n shoot models from Pentax, Fuji, Sony, Oly and Panasonic.
Hope this helps! Have fun shopping.
