Big Bear in September offers peaceful afternoons and tranquil evenings. The summer crowds have left for the summer, and it is just you and the forest when visiting Big Bear in September.

After a long and hot summer in the city, you can’t beat getting up to the mountains for some fresh air. All of the main summer attractions are still open just without the crowds.

Find the best alpine trails as you climb to the summit and overlook the San Bernardino National Forest. Big Bear Lake is still warm, and you can cool off with a refreshing float at one of the sandy beaches near the dam. Whichever experiences you are looking for, Big Bear always serves up a great adventure!

Big Bear Lake is open for boating and recreational activities on the water.

Summer Fishing

Spending your days on the lake is the best thing to do in Big Bear during the summer months. One of the best places to catch fish on the Lake is from the beach shoreline on the north side of the lake near the dam.


Helicopter Tours

Available Year-Round

Head to the Big Bear Airport and lift off over the mountains on a scenic helicopter tour. The helicopter has a capacity for you, 2 friends, and of course the pilot.

I have done the tour before and can say it is amazing. You get to see views of Big Bear that you didn’t know even exist. The tour brings you over alpine lakes, waterfalls, and dives down into scenic valleys.



For action-packed adrenaline check out doing a zip line experience with Action Tours California! This is a scenic way to learn about the specific nature of the National Forest while enjoying the thrill of flying on 9 different choice zip lines. Get a new kind of high with this high-altitude fun!
