Tettegouche (http://www.dnr.state.mn.us/state_parks/tettegouche/index.html) in September should be a great time!
From the parks website:
Come to Tettegouche for a great sense of the North Shore: the spectacular overlooks at Shovel Point; rocky, steep cliffs and inland bluffs; the cascading 60 ft. High Falls of the Baptism River; and the historic Tettegouche Camp where visitors can stay the night.
This is a hiker's paradise with miles of trails that overlook the Sawtooth Mountains and wind down to inland lakes accessible only by foot.
The Palisade Valley Unit features broad scenic vistas coupled with an expanse of multi-use, four-season trails. Two more trout lakes complement the fishing opportunities within the rest of the park.
The park is also known for rock climbing opportunities and quality birdwatching in the spring, summer, and especially the fall.
We will be in Group Site #1.
The camping trip will be from Friday to Sunday. I should get to the park by mid-afternoon. If you wish to carpool with someone post a message in the comments.
The cost will be $25. You can pay by Paypal. Prepayment will be required for attendance. I will give full refunds (less any fees not refunded to me) up to September 1st. The reason for this is to prevent people from cancelling at the last minute because of bad weather.
Please e-mail me with any questions.
