Make the AC fans run. At 250 that engine won't last long. Turn on the AC and set the temp to max warm. The compressor will not cycle much at all at max hot temp, but if the fans run continuously then it should get cooler. Also check the coolant level next time she is cold both the radiator itself and recovery bottle.
Not sure what to tell you with the temp difference in the radiator hoses and engine temp ashigh as 250.
1.Low coolant
2.Thermostat broken shut
3.Not enough antifreeze, pure water boiling
4.Not sure on a 95 Camry check online to see if the cooling system needs to be bled. Air pocket could be you primary problem.
5.It could be ahead gasket is giving out, have you lost coolant when it gets that hot?
Ride with the windows down and heat on max fresh air.
Bottom line is find away to make it run cooler or you will soon be faced with major engine work.
Of course all of this assumes your temp readings are correct. When I was working on cars daily I could hold my hand on a 180 degree top hose for about 5 seconds before I had to take it off or risk burning, at 250 my hand would be off in less than a second.
