Summer Rentals
Summer in Island Park is breathtaking - and one good way to get out into nature, is to be on an UTV.  From moose to deer and maybe an occasional black bear - there's tons to be seen.  Many old forest service roads are accessible by RZR and even the old Railroad bed is designated to this type of travel (if it's 50" wide or less).  We do our best to get you on the correct trails.

Our 24' pontoon boat is great for pleasure rides with family and friends (holds up to 15 people) - or entertaining. Tow a tube or two, jump into the water for a swim, go fishing and then have a BBQ (BBQ not included).  The large flat area allows kids and adults to move around freely without any restrictions. Our pontoons allow you to pull into any beach or bay at a whim, easy to park and play. $400 - 8am to 5pm

Aqua Trampoline & Paddle Boards

The ever famous "Aqua Tramp" can be setup near your waterfront property (on Island Park Reservoir) for days and days of fun.  Rental is $350 per day (including setup) 8am to 5pm.  Perfect for family reunions and other get-togethers.  Of course, we advise the use of common safety practices when using any of the water trampoline and water sports equipment.  

The fast-growing sport of stand up paddleboarding (SUP) is a fun, easy way to go play on the water. With a minimum of equipment, you can paddle anything from lakes to rivers—no waves required. Paddleboarding offers an amazing full body workout and is becoming a favorite cross-training activity for skiers, snowboarders and other athletes. And since you're standing at your full height, you'll enjoy excellent views of everything from waterfowl to what's on the horizon. It's almost like walking on water!
Boards rent for $40 per day (8am-5pm)
