thats too broad a question for me
it depends what what you have in mind
ok ill try:
get a copy of "Alberta Fishing Guide" from C Tire or Mowhawk then drive west till you hit the forestry trunk road. Go north or south and start exploring.
2 recommendations:
Abraham Lake and area (its getting farther out but worth it)
Sheep River Drainage upstream from Black Diamond
Make sure you bring, camera, and someone to enjoy it with.
Im sure you can add to the list
Tip:
Go Prepared in terms of food shelter clothes emergencies
