Mount Fromme, like the other mountains of the Pacific Ranges, is covered with temperate rainforest of the Coastal Western Hemlock Zone.

In the case of Mount Fromme, this is largely secondary growth forest, since the mountain was extensively logged in the early 20th century.

This name, first proposed in 1928 when Fromme was reeve of the District of North Vancouver, became official on December 7, 1937.

[7] Mount Fromme features various trails, many of which are part of the NSMBA (North Shore Mountain Biking Association).

There are approximately 40 mountain biking trails in total though many of them have become not ride-able due to lack of maintenance.

It is most notable for the giant drop at the opening of the trail which launches off from a massive boulder.

It is rated as a triple red diamond trail (the hardest difficulty) but is now decommissioned and is in disrepair.

It contains massive ladder bridges, many of which are over 10 feet in the air and under six inches thick, giant jumps and wall-rides, almost all of which are in disrepair and unsafe to ride.

The Flying Circus is a triple red diamond run constructed by North Shore biker "Dangerous Dan".

It starts just below Upper Oil Can and is known for the extremely challenging skinnies and ladder-bridges which are very thin and high in the air.

The summit trail to Mount Fromme winds through second growth forest, gaining a final 350 meters of elevation.
