Riverside Convention Center — Riverside, CA


The 2023 Annual Meeting will be held at the brand-new and extremely spacious Riverside Convention Center.  

We have pre-purchased a limited block of hotel rooms at several of the hotels adjacent to the convention center.  The three hotels below are each within one block of the convention center in easy walking distance.  

  • Marriott Downtown Riverside Block 1:  $150/night AND Block 2:  $165/night.  Due to a recently increased federal per diem rate, we have rooms available at two different rates. These rates are available to anyone in our group, and you do not need to be a federal employee to book in either block.  First come, first served for the lower cost rooms.  These rates are for single occupancy.  $10 per additional person charge per night.

There are three major airports near Riverside: Ontario International Airport (ONT), Los Angeles International Airport (LAX) and John Wayne Orange County Airport (SNA). Ontario International Airport (ONT) is about 20 miles northwest of Riverside and is the most convenient air travel choice. There are public transportation options between the Ontario Airport and downtown Riverside. Uber and Lyft are also widely used in this area. We will set up online bulletin boards to facilitate ride shares. More information is coming soon.


The Southern California Chapter of TWS is organizing local field trips and hikes before the meeting which will highlight the flora and fauna of the area! There are several open space areas that are within a ten minute drive of the convention center – some of which are listed below. The Riverside-Corona Resource Conservation Center is also nearby which offers tours and demonstrations of restoration, sustainable land practices, and research projects they are a part of. Here are some open space areas to check out in the Riverside area: 

  • Fairmount Park;
  • Mount Rubidoux Park;
  • Ryan Bonaminio Park;
  • Sycamore Canyon Park. 
  • If you have time to drive further afield – be sure to check out Joshua Tree National Park which is less than two hours from the convention center.two
