 walked up a forested ramp in December 1884 to scale the plateau. This is the same route hikers take today.

Today, Mount Roraima is a destination for backpackers. Almost all who go up the mountain approach it from the Venezuelan side. Most hikers hire a Pemon Indian guide in the village of Paraitepui, which is reached by dirt road from the main Gran Sabana

 road between kilometre 88 and Santa Elena de Uairen. Although the path to reach the plateau is well marked and popularly traveled, it is easy to get lost on top of the mountain, as there are few distinct trails and the near constant cloud cover on top and the uncanny rock formations make visual references problematic. Paraitepui can be reached easily by four wheel drive vehicle, with great difficulty by car if the unpaved road conditions are unusually fine, or by foot in about a day.

From Paraitepui, most hikers take one day to reach the base of the mountain, and then another day to follow "La Rampa" a natural staircase-like path, up to the top. Another two days are typically needed for the return, and many people spend one day and night on top of the mountain, making five days in total. Longer treks can reach the northern portion of the tepui, mostly in Guyana, with less explored and more intriguing sites such as Lake Gladys, although this offers more dangers than its more popular southern part and should only be attempted by well-supplied groups. The less adventurous can also reach the mountain, weather permitting, by helicopter tours available from the nearby Venezuelan city of Santa Elena de Uairén

The only non-technical route to the top is the Paraitepui route; any other approach will involve climbing gear. Mount Roraima has been climbed on a few occasions from the Guyana and Brazil sides, but as the mountain is entirely bordered on both these sides by enormous sheer cliffs that include high overhanging (negative-inclination) stretches, these are extremely difficult and technical rock climbing
