GMRS Radios - General Mobile Radio Service, will operate at 35 or more miles, but only through a REPEATER. The radios can operate in Simplex (receive and transmit on the same frequency) or Duplex, with the radio transmitting to a repeater and them listening on a different receiver frequency (called a split) to the REPEATED output of the Repeater.
Keep in mind to be legal though you have to have a license to operate a GMRS radio. Like Ham Radio equipment, most sellers will not ask if you have a license to buy one, but that does not mean you don't need one. For simplex operation, you probably would never encounter and FCC "Listeners" especially if you are using them out in the woods. But through a repeater, you might as the repeater operator / control operator is supposed to keep track of who uses is and you need a CALL Sign, which can easily be looked up and verified.
