What walkie talkie has the longest range?

GMRS radios with 5W output (like the Midland GXT1000VP4) have the best range. With a repeater, GMRS can reach 20+ miles. For truly long range, amateur (ham) radio with proper antennas can reach hundreds of miles.

Do walkie talkies work in mountains?

Yes, but range varies dramatically. Ridge-to-ridge with line of sight can be excellent (10+ miles). Valley-to-valley through mountains may be less than 1 mile. Higher wattage and GMRS frequencies help.
