To protect wildlife, 720 acres of the park have restrictions. This doesn't hurt much as the overall park spans nearly 4,000-acres. Off of North Gasoline Trail, there is an off-leash dog park available. This is the only section of the park you are allowed to have your dog off leash, but it spans a lot of ground and makes for a great place to throw a frisbee or play fetch.
The area is not fenced, and so escape is quite easy and possible, so make sure your dog can remain in sight and voice control at all times. There is plenty of vegetation and trees for shade and the park stays pretty green over the summer. Overall, this is a gorgeous park with plenty of room to stretch your legs with your canine. You can take the dogs on the trails as long as they remain leashed, and there are enough walking trails to wear you out hundreds of times over.
This park is traversed by bikers, hikers, runners, and so many more varieties of cross-country and downhill sports. Beautiful streams and rivers flow through the area and the facilities are abundant and well maintained. There couldn't be a better place to spend the day if you want to get outside and in Anchorage, that's a hard thing to say.
Beautiful lakes spatter the tremendous park, skiing is available during the winter months. After a few runs, you can go and watch the dogs mush down the gorgeous white trails.
