Creating a route map with points of interest along that route on a single map to show on a node

I have a route on a map that shows the route for that node it has been uploaded to.

I now want to show many other points of interest along that route using geolocation which then shows on a single map as the route and then shops, water, accomodation etc along that route.

Then for this single map with all this data to (route and other points of interest) to be shown on each route node.

How is this possible?

At the moment the only way I can think about doing it is having separate geolocation mapping fields on the route node, the first being GPX Route field, then Shop Location field, Water Location field and so on where I use markers for each map to show these locations.

Then I have to build a block view, select all the mapping fields to show on a map and use contextual filtering to show that map for each node?

One issue I have seen is that I can't add multiple geolocation mapping fields on to one view to show all the different types of points of interest along the route.

Or is there another way to do this?
