Advisories
Camping
There are boat-accessable sites for short-term camping on a first-come, first-served basis. This is an undeveloped park and any campsites are to be user-maintained; please leave “no trace.
Facilities
We encourage visitors to conserve wood and protect the environment by minimizing the use of fire and using campstoves instead. Campfire bans may be implemented. To preserve vegetation and ground cover, please don’t gather firewood from the area around your campsite or elsewhere in the park (this is a ticketable offence under the Park Act ). Dead wood is an important habitat element for many plants and animals and it adds organic matter to the soil.
Activities
Lasca Creek trail is not maintained and leads through prime bear habitat – please use caution. DO NOT CUT NEW TRAILS. Shortcutting trails destroys plant life and soil structure. For your own safety and the preservation of the park, obey posted signs and keep to designated trails.
Anyone fishing or angling in British Columbia must have an appropriate licence.
