Much like the level 45 Misty Woods and Necropolis dailies,
the level 50 cap has a wide selection of dailies for you to complete.
I will list the most commonly completed ones here.
Nine dailies can be picked up here. The dailies consist of gathering items, killing mobs, killing one world boss, and two blue dungeons. After collecting the quests at Herbalist's Lodge (assuming you unlocked all of them while leveling up), leave Herbalist's Lodge and complete all of the quests as you come across them. The last ones you should complete are outside of Chuanka Frost Cavern.
After completing those, you can move to F8 to complete the blue dungeon dailies. There are a total of four: Chuanka Frost Cavern, The Shrieking Cavern, Talus Dungeon and Ogong's Folly. These should be reminiscent of "The Big 4" from Moonwater Plains. Quite literally, one of the dungeons has monkeys and Ogong. To easily reach these dungeons, you can alternatively use the portal system in Zaiwei.
After you've completed those, exit F8 and pick up the next set of dailies at Northreach.
Northreach will start off with two quests - gathering items and killing mobs. Later on, after a story quest expansion, another blue dungeon daily can be picked up here.
After these two quests, you can proceed with the 3 purple dungeons (or 4 blue if you skipped them earlier). You can access them through F8 or by using Zaiwei's portal system.
All of the dungeons in Silverfrost can be accessed in Zaiwei. The Cardinal Gates is a common spot for people to look for parties, as each dungeon has a dragon pillar outside of it (F7). The 3 purple dungeons that will be introduced with Silverfrost are Lair of the Frozen Fang, Avalanche Den and Awakened Necropolis. All 3 dungeons will have 6-man and 4-man variants, with special items such as costumes dropping only in 4-man. These purple dungeons cannot be accessed through normal means in the open-world. You can only get to them through F8 or the Zaiwei portals (though you may be able to find remnants of their old open-world portal counterparts if you search hard enough).
Two new 24-man areas will be introduced on Silverfrost's release - Beastbog and Frostscale Basin. These two areas are a bit different than the already-familiar Poharan and Nightshade Harbor 24-man dailies. Beastbog has 3 dailies - two for mob killing, and one for killing the main boss of the area. The catch is that the main boss only spawns after the two snake minibosses have been killed a certain amount of times. It can be hard to get this guy to spawn if the channel isn't working together. Frosctscale Basin has a 100 mob killing quest, a quest to gather items and a quest to defeat each of the 3 bosses. The 100 mob killing quest is quite a grind if you are by yourself. There is another boss in this area that spawns after you kill all the 3 minibosses for your quest, you can kill this big boss for an achievement and the field quest. Kill him 3 times (by killing the minibosses 3 times per big boss spawn) and an even greater version of the big boss will appear. Lots of cooperation is required for this 24-man as well.
Another good area for daily quests, Plog's Sanctum has mob killing quests and boss killing quests. 3 bosses spawn in this area, and all must be killed to spawn the big frog boss which you can kill for an achievement and field quest.
Doing all of your Snow Dailies can net you upwards of 15 gold per day
as well as a healthy chunk of experience. Don't neglect them!
