Marina

The Gates of the Mountains Marina is on the south end of Holter lake just 20 miles north of Helena off Interstate 15 at exit 209 (Gates of the Mountains).

The marina is owned and operated by a non-profit membership organization called Gates of the Mountains, Inc.. The by-laws of the organization allows for 150 family memberships. Only members can occupy or lease a dock in the marina but there is a public ramp open from 7:30 am through 10:00 pm.

The ramp cost is $8 for boats on trailers (including personal watercraft) and $5 for boats without trailers. There is an exit gate that allows for boaters to get off the property after 10pm. The mission statement for the club stresses conservation, education and pleasure boating.

The marina consists of 144 private docks ranging in size from 20’ to 30’. The 30’ slips have shore power. All the slips have wings on both sides making mooring easy and protected. There is an on-site manager that acts as a security guard to protect your assets when you leave the marina. If you wish to rent a slip (dock) fill out an application and send it to the P.O. Box. After receiving the membership application the board of directors will vote on accepting the application and you will be notified about becoming a member.
