Getting excited about our trip to Yosemite!! As first timers in the area, we decided to dedicate a large portion to backpacking and sight seeing. 2 people, the hike will be 2-4 nights, after this post I'm sure I can either add or rule a few things out. I am looking for some advice on trailheads, weather, bear safety, and any other tips or recommendations from some more well-versed hikers.
Picking up a rental car in LA on early on a Sunday this June and headed towards Sequoia or Kings Canyon for lunch then on to Yosemite. Haven't decided where to stop Sunday night before starting, but there is availability in campgrounds in the park and hotels just outside. Monday would start the hike, park in the valley and take transit to Tuolume Meadows and hike down to the valley (after researching, I am not sure if that area will be open due to weather or if transit will be running? (advice on starting point?). First night was going to be around the Vogelsang High Sierra Camp area (I believe it will be closed) or around Merced Lake. I have heard some people skip Vogelsang because of the steep uphill. Second night merced lake or Little Yosemite Valley depending on our pace we would like to hit Half Dome the next day. Do you need passes in advance for Half Dome? Last night stay in the Valley somewhere. We have from Sunday night till Thursday to complete our trip, the next leg requires us to be in Sacramento on Friday morning. Here is a trail that we will be mimicking: http://www.everytrail.com/guide/tuolumne-meadows-to-yosemite-valley/map#poi-5
A few other questions: 1. bear canisters vs. bear bags. Being from FL, I have not ventured into bear country. I know we will need some bear proof system by park rules, but I don't want to spend a ton. What about OP Sak 9X10 Airtight Waterproof Pouch Bags (they claim to be bear proof)
2. backcountry permits. Would you get one for sunday night even if we are un sure where we are staying? We were told to camp somewhere in the valley the last day and expect to be exhausted.
3. weather conditions. What should we expect? lows? snow/rain?
We have experience with all of our gear except we both got new packs. We will be doing a test run next weekend! Thanks for reading and any advice would be extremely helpful
