The capitol of Montana, Helena, lies between the Elkhorn and Garnet Mountains. The Last Chance Gulch was where the gold rush happened, and the Last Chance Stream in Helena is remembered as a crooked trail that still follows where the stream once ran. You can climb to the top of Mt. Helena to view the city from the peak at over 5,000 feet.
There is plenty to do while you are here, and the activities will keep the whole family busy. The outdoor recreation is ample, with many lakes and forested trails through the mountains. In town, there's everything from touring the State Capitol building to visiting skate parks and carousels. Take a day-trip to Spring Meadow Lake State Park. Take a boat tour of the rivers.
Accommodations are abundant. You won't have a problem finding any number of motels, hotels or lodges. Take your pick of one of many Bed & Breakfasts. Camping isn't a problem, and you can find campgrounds around the Missouri River and Canyon Ferry Lake.
To get to Helena from Missoula, it's a short 1 hour and 42 minute drive south on I-90 east then east on US-12. You will be so glad you came!
