Sitting at 9,017 feet in the Colorado Rockies, Lake Dillon is one of the most scenic paddle boarding destinations in the state. Whether you are a first-timer or an experienced paddler, Dillon Reservoir has something for everyone. This guide covers everything you need to know before you hit the water.
Why Lake Dillon Is a Top Spot for Paddle Boarding in Colorado
Lake Dillon, also known as Dillon Reservoir, spans over 3,000 acres and offers stunning 360-degree views of the surrounding mountains. The calm morning water, clean alpine air, and easy access from Denver (about 70 miles west) make it a go-to spot for paddle boarding in Colorado. It is family-friendly, beginner-accessible, and rewarding for advanced paddlers who want to cover serious distance on open water.
ANS Inspection and Permit Requirements (Read This First)
Before you launch at Dillon Reservoir, your board must pass an Aquatic Nuisance Species (ANS) inspection. This is required by Colorado law to prevent the spread of invasive species.
- Inspections are done at the launch site before you enter the water
- They are quick (usually just a few minutes) and free
- You must also purchase a Colorado Watercraft Registration or a Non-Motorized Vessel Pass if your board has not been registered in Colorado
- Failure to comply can result in a fine
Plan to arrive a few minutes early to account for the inspection line, especially on summer weekends.
Best Launch Spots for Paddle Boarding at Lake Dillon
There are three main launch points around the reservoir, each with its own advantages.
Dillon Marina
Dillon Marina is the most popular and well-equipped access point on the lake. It offers:
- Paved parking and restroom facilities
- A designated non-motorized launch area
- Easy entry into open water with minimal obstacles
- Close proximity to rental shops if you need gear on-site
This is the best starting point for beginners or anyone unfamiliar with the lake. Morning launches here offer the calmest conditions before the afternoon wind picks up.
The iROCKER ALL AROUND 11' 8.0 inflatable SUP is easy to carry from parking to the water at Dillon Marina
Frisco Bay
Located at the northwest end of the reservoir, Frisco Bay is a quieter alternative to Dillon Marina. It is ideal for paddlers who want:
- Less boat traffic and a more relaxed atmosphere
- Shorter distances across shallower bays
- A scenic view toward the Gore Range
Parking is available at the Frisco Bay Marina. This spot is great for families with young kids or anyone who prefers a calmer, sheltered section of the lake.
Frisco Bay offers calm, shallow water that is perfect for paddlers of all ages and experience levels
Snake River Inlet
Snake River Inlet sits at the southern end of the reservoir where the Snake River flows in. It is a more secluded entry point and popular with paddlers who want to explore narrower channels away from motorized boats. Note that parking is more limited here and the terrain to the water can be uneven, so it is better suited for experienced paddlers.
What to Expect When Paddle Boarding on Lake Dillon
Paddling on a high-altitude reservoir is different from ocean or flatwater lake experiences. Here is what to prepare for.
Wind, Weather, and Afternoon Storms
Lake Dillon is known for fast-changing weather, especially in summer:
- Mornings (before 11am) are typically calm with flat water
- Wind picks up significantly in the afternoon, often creating choppy conditions
- Thunderstorms can roll in quickly after 1–2pm from July through August
- Always check the weather forecast before you go and plan to be off the water before noon if storms are expected
The general rule among local paddlers: launch early, leave early.
Cold-Water Safety and Best Time of Year to Paddle Board at the Reservoir
The reservoir sits at high elevation, which keeps water temperatures cold even in peak summer:
- Water temperatures range from 50°F to 65°F (10–18°C) in summer
- Falling in means cold shock is a real risk, even on warm days
- Wear a wetsuit or drysuit if you plan to paddle in early summer (June) or fall
- The best months for paddle boarding at Lake Dillon are late June through early September
Gear and Equipment for Paddle Boarding at Lake Dillon
Having the right gear makes your trip safer and more enjoyable. Here is what to bring.
Why an Inflatable Paddle Board Works Best at High Altitude Lakes
If you are driving up from Denver or the Front Range, an inflatable SUP (iSUP) is the most practical choice:
- Deflates and rolls into a backpack-sized bag
- Fits easily in any car without a roof rack
- Ideal for rocky or uneven launch areas
- Modern drop-stitch technology makes them rigid and stable on open water.
Look for boards with welded-seam construction (heat-fused, no adhesive) rather than glued seams. Welded seams maintain pressure and shape even in cold water and don't fail when the board is dragged across rocky shoreline (which is most of Lake Dillon's access points). iROCKER builds welded seams into 100% of its 2026 boards, the only inflatable water gear brand to do so.
For first-time paddlers and families launching at Dillon Marina or Frisco Bay, the iROCKER CRUISER 8.0 is a smart pick. It's our most stable family-friendly board at 31 inches wide, with welded-seam construction that holds up to repeated sandy launches. The iROCKER ALL AROUND 11' 8.0 is the better all-rounder for longer paddles or open water with light chop.

Safety Gear You Should Never Leave Behind
Colorado law requires all stand-up paddleboarders to carry a personal flotation device (PFD). Beyond that, pack:
- Leash (ankle or coil style) to keep your board close if you fall
- Whistle (required by USCG regulations)
- Sun protection: sunscreen SPF 50+, UV-protective clothing, and sunglasses
- Water and snacks for longer sessions on the water
Rules and Regulations on Dillon Reservoir
Keep these rules in mind before you paddle:
- ANS inspection is mandatory before every launch, every time
- Non-motorized vessels must display a valid Colorado registration or vessel pass
- Stay clear of the dam and restricted zones marked by buoys
- No paddling after dark
- Dogs are welcome but must be on a leash at access points
- Respect no-wake zones near the marina and swim areas
Fines for violations can be steep, so it is worth taking five minutes to understand the local rules before your trip.
