As of 2020, the Moul Falls trail holds the record for the most popular short trail in Wells Gray Park, short meaning 30 minutes to 1 hour one-way. Consequently, the parking lot which seemed huge when it was built in 2005 has become woefully inadequate. On warm summer days, vehicles overflow the parking lot onto the shoulders of the Park road. The Ministry of Transportation has been very concerned about this congestion. One of the factors that delayed an expansion was that the parking lot is not in Wells Gray Park, yet the trail goes into the Park. Various ministries were involved including Transportation & Infrastructure; Forests, Lands & Natural Resource Operations; and Environment (BC Parks). In October 2020, work began to expand the parking lot to about three times the current size. The new area was barricaded over the winter to allow the fill to settle and compact, and the expansion should be opened in early summer 2021.
Ministry of Forests installed a pit toilet at the parking lot which opened in July 2018. The Wells Gray Gateway Protection Society, Tourism Wells Gray, and the author had been urging government to build this facility for a few years prior. This is the only toilet along the trail.
Three interpretive signs were installed along the Moul Falls trail in September 2019. These are located near the parking lot, at 2.2 km where there is a view of Grouse Creek, and at the top of Moul Falls. A grant from the Park Enhancement Fund to Tourism Wells Gray made these informative signs possible.
