Bogus Basin is one of the best and, at only 20 miles from Boise, most convenient skiing and nature areas in Idaho. It's usually open for skiing from November until March-April (depending on snowfall) and it's one of the more accessible, family-friendly ski resorts in Idaho. The main slopes, Deer Point and Doe Point, aren't the biggest or most challenging slopes in the state but they make for a fun day out, especially if you're not an expert skier or just want to have some fun with the family. One thing I'd especially recommend is tubing down the mountain. It's a great option if you're on vacation and just want to have a fun day-trip to the mountain rather than strap on your boots and do some serious skiing.
Also, one of the best parts about a trip to Bogus Basin is the drive up there. The road to Bogus Basis winds through the mountain and offers great views of Treasure Valley and Boise, not to mention the simply beautiful mountain scenery. There are a couple paid parking lots throughout the area and luckily they don't murder you with the prices. Speaking of which, Bogus Basin is, in general, a very reasonably prices (if not downright cheap) ski resort. Again, it's not big or fancy, but rental and access fees are doable for a family of four and they have great deal on classes for the kids.
All and all, I'd say that Bogus Basin isn't the best place if you're looking to spend an entire week skiing challenging slopes. But, if you're looking to spend a few days with your family enjoying the mountains and doing some fun slopes without going broke or jut want to have a great day-trip from Boise, Bogus Basin is the best place around.
