for the record, I meant Siyeh Peak, which is different from Siyeh Pass. Though both seem to get universal praise. They're the same trail for about 60% of the way. The pass trail is longer and less treacherous, very scenic. The peak is somewhat more of a challenge, and it takes you to a 6,000 foot wall. There's a female grizz who is pretty chill that hangs out around there. she's still a bear, and she had some pretty large cubs last year. so just don't be an idiot if you go out that way.
Bowman is the lake you can drive to. that whole area of the park is less packed than the areas around the going to the sun road.
