I would guess a helicopter, but I'm sure you could climb it.

Mount Roraima and Mount Aoyan are the only flat-topped mountains in the Canaima National Park that can be climbed by hikers, with a monthly quota of 200 people.[9][16] Its ascent takes three to five days in total,[7][14] the summit route is on a natural slope on the southwestern cliffs of Mount Roraima,[13][15][21] it does not require any special equipment or training, so it is chosen by almost all hikers,[15][21] the only difficulty is that some streams and small waterfalls may become difficult to pass under heavy rain.[14][21]
