Heho, I'm Daniel and going to visit the Yosemite national park in early Oktober during my bike-tour through the south-west of the USA!
I would have some questions, maybe you've got experiences and answers! :)
1. In early Oktober on the high point of the Tioga pass: Will I have to expect snow?
Wouldn't be a problem, but still nice to know in advance :)
2. As the incline is quite big and most of the campsites are closed at this time of the year:
I think Porcupine creek is the only open one... Do you know if there is an opportunity to get the allowance to camp during my passing near the road? Not at an campsite..
If you want: Can I get kind of an front-country permit instead of an back-country permit?
3. Does somebody have any experiences with black bears?
I'm not so afraid of meeting one during biking or hiking, but what do you do if one visits you, when you already build your camp? Talk friendly and offer some tea? ;)
4. There are several giant sequioa groves:
Is Toulumne grove fantastic enough or should I visit Mariposa Grove instead/ too? Toulumne grove would be on my way, Mariposa would be an day extra!
So thanks so far, I hope somebody can help somehow ;)
