Frequently Asked Questions

We ask that persons deflate their tubes before boarding the bus. Passengers with deflated tubes will have priority. This helps us make room for up to 50 riders during peak hours. If you must inflate your tubes, only individual, single-person tubes are allowed, and if there is not enough room for your inner tubes you will be asked to wait until the next shuttle.

Every other type of inflatable, including double tubes, inflatable kayaks/paddleboards, unicorn floaties, blow-up alligators, and other random, crazy inflatables are required to be deflated and fit under your seat or on your lap.

With limited space please be considerate of others by limiting your gear. Shuttle drivers can turn away passengers and/or their belongings at their discretion.  The following items are permitted on the bus.

  • Small coolers, bags, backpacks, drybags, etc. Should fit on your lap or under your seat.
  • Food and beverages. No glass!!

No; however, priority will be given to passengers that bring deflated tubes. Have a plan for how you will inflate your tube when you arrive at the river access. There are currently no inflation devices at river access points or on the buses. You can find small, manual pumps for under $20 at most hardware and outdoor sporting goods stores.

All kayaks, paddleboards, double-tubes, and other types of inflatables are not allowed to be inflated on the bus. They must be deflated and fit under your seat. Only single-person inner tubes are allowed to be inflated.

No, RSVP is not required; however a select number of seats are reservable by RSVP. Groups are expected to show up 15 minutes early and tubes must be deflated on the bus. 

Permits are not required on Saturdays or Sundays or weekdays after 5 PM. All parking passes on campus (except lots H, J, and K) can now be purchased with the Passport App. Parking costs $1/hour. You may also use the kiosk for parking if you park in lot M (near Jacob's Island dog park). You can also purchase a day-pass for $8 on the parking website. Please visit UM Parking for maps and more information.

Float time is heavily dependent on streamflow and wind. In general, the Sha-ron to campus float takes about 1 hour in early July and 2-2.5 in August. For a Milltown to campus float, double the time. Estimates are for time on the river and don't include shuttle and preparation. To be safe, always plan for the trip to go longer than you expect. If you catch the shuttle at 6 PM, you may be getting off the river after dark. 


ASUM Transportation is only responsible for the safety of its passengers while on the bus; passengers are responsible for their own safety on the river. Check the weather forecast before you go and be sure to wear appropriate clothing to protect from sun, rain and cold. 

Under extreme weather conditions, such as severe thunderstorms, shuttle service may be cancelled. In the event that service is cancelled the live tracker will be updated to notify passengers.

UDASH SUMMER RIVER SHUTTLES RIDER EXPECTATIONS Priority boarding goes to those with DEFLATED tubes. Bring a manual pump to fill up your tubes upon drop off. If we run out of room and your tube is not deflated, you will have to wait for the next shuttle. You may RSVP ahead of time to reserve your spot by emailing udash@umontana.edu. Questions or comments may also be sent to this email. Shuttles leave on the hour every Thursday-Sunday from 12-6 pm. Half-hour service is available from 1-4 pm on Saturdays and Sundays. Please be early to board because the shuttle will not wait for you. All items must fit under your seat or on your lap. All food and drink items on the bus must remain sealed. Buses drop off at Sha-Ron River Parking and Milltown State Park. If you float from Milltown on the 6 pm shuttle, be advised that you could still be on the river after dark. We reserve the right to refuse service to anyone who is rude, disrespectful, or does not comply with the above expectations. Thanks for riding UDASH!
